C. All the chemical processes that take place in the organelles of the cells

D. The supply of nutrients to the body cells

Answer is A: Anabolism refers to the process of constructing/building molecules

(think anabolic steroids). B refers to catabolism. C is metabolism.

5. Which major organ lies deep to the right hypochondriac region?

A. Stomach

B. Spleen

C. Liver

D. Duodenum

6. Which plane divides the body into dorsal and ventral regions?

A. Transverse

B. Axial

C. Corona

D. Sagittal

Answer is C: Dorsal and ventral = front and back—a coronal section that divides the body into these sections.

A. A condition of having too few chondria

B. The region of the abdomen inferior to the ribs

C. A person who often complains of an ailment

D. Having insufficient cartilage in the knees

Answer is B: In this case, “hypo-” means below, while “-chondral” refers to the cartilage joining the ribs to the sternum (the costal cartilage). The regions of the abdomen immediately inferior to these rib cartilages (on the left and right sides of the body) is what is being referred to.

9. If a medical image displays internal anatomy in the mid-sagittal section, which of the following describes the section?

A. A vertical section through the nose and umbilicus that divides the body into right and left halves

A. On the ventral surface of each knee

B. On the abdomen, immediately superior to each thigh

C. It is the region between the two lungs

D. It is superior to the heart and inferior to the larynx

Answer is B: Inguinal refers to two of the nine regions that the abdomen surface is usually divided into. In this case, to the two most inferior, on either side of the pubic (or hypogastric) region.

22. What part of the body is referred to as the plantar region?

A. The crease (anterior surface) of the elbows

B. The backs of the hands

C. The palms of the hands

D. The soles of the feet

Answer is D: The inferior surface of the feet that make contact with the ground is the plantar region. Plantar warts occur on the soles. Plantar flexion of the foot is the act of “pointing the toes”.

A. The elbow is proximal to the shoulder.

B. The phalanges are distal to the carpals.

C. The ribs are proximal to the sternum.

D. The elbow is distal to the knee.

A. Superior to the rib cage.

B. Inferior to the thoracic vertebrae.

C. Located between the thoracic and sacral vertebrae.

D. Fused into a single bone called the sacrum.

Answer is A: Cervix refers to “neck”. The cervical vertebrae are in the neck hence are above (superior) the rib cage.

28. Which term describes the location of the adrenal glands with reference to the kidneys?

A. Proximal

B. Distal

C. Superior

Answer is C: The adrenal glands are on the cephalic side of the kidneys. Being closer to the head, they are termed “superior to the kidneys”.

29. Which bones are located distal to the elbow and proximal to the wrist?

A. Carpals

B. Radius and ulna

C. Tarsals

D. Humerus

Answer is B: Distal to the elbow means further along the arm towards the hand— this eliminates the humerus. Proximal to the wrist means closer to the body than the wrist—this eliminates the carpals. The tarsals are in the ankle.

C. Integument, muscle, superficial fascia, bone, marrow

D. Hypodermis, subcutaneous fat, muscle, marrow, bone

Answer is B: Choice A is incorrect as hypodermis is more superficial than muscle. Choice C is wrong again because superficial fascia (which is a synonym for hypodermis) is more superficial than muscle. Choice D is wrong as marrow lies within the bone, and also hypodermis and subcutaneous fat are almost synonyms.

31. Which of the following describes the position of the pinna of the ear with respect to the nose and chin?

A. The ear is superior to the nose and distal to the chin.

B. The ear is proximal to the nose and distal to the chin.

A. Vertebrae are posterior (or dorsal) to the sternum and medial to the kidneys.

B. Vertebrae are superficial to the sternum and deep to the kidneys.

C. Vertebrae are superior to the sternum and inferior to the kidneys.

D. Vertebrae are lateral to the sternum and medial to the kidneys.

Answer is A: Vertebrae are posterior (or dorsal) to the sternum, which means they are closer to the back surface and medial to the kidneys, which means that the vertebrae are closer to the body’s midline.

A. It is in the dorsal cavity.

B. It is in the ventral cavity.

C. It is in the abdominopelvic cavity.

D. It is not located in a body cavity.

Answer is D: The musculoskeletal system is located in the arms and legs, and surrounding, but outside of the abdominopelvic, thoracic and dorsal cavities.

35. Which of the following is/are the contents of the dorsal body cavity?

A. Heart and lungs

B. Brain and spinal cord

C. Viscera

D. Gut, kidneys, liver, pancreas, spleen, bladder, internal reproductive organs

38. The dorsal body cavity contains which of the following organs?

A. Brain

B. Brain and spinal cord

C. Brain, spinal cord and heart

D. Brain, spinal cord, heart and kidneys

Answer is B: Dorsal refers to the back and is opposite to the ventral. Only the brain and spinal cord occupy the dorsal cavity. All other answers are incorrect.

39. What structure separates the thoracic cavity from the abdominal cavity?

Answer is B: The muscular diaphragm physically separates this two ventral cavities.

40. What structure separates the abdominal and pelvic cavities?

A. There is no separating structure.

B. Diaphragm

C. Peritoneum

D. Dura mater

Answer is A: The pelvic cavity is not physically separated from the abdominal cavity.

For example parts of the small intestine are located in both “cavities”.

41. In which cavity or cavities does the digestive system lie?

A. Abdominal cavity

B. Abdominal and pelvic cavities

C. Thoracic, abdominal and pelvic cavities

D. Dorsal, thoracic, abdominal and pelvic cavities

Answer is C: The oesophagus is within the thoracic cavity, while the remainder is in the abdominopelvic cavity.

42. What structure separates the thoracic and abdominal cavities and what is it made of?

A. The mediastinum, made of serous membranes

B. The diaphragm, made of skeletal muscle

C. The diaphragm, made of smooth muscle

D. The pleural cavity, made of visceral and parietal layers

Answer is B: The diaphragm physically separates these two ventral cavities. It is made of skeletal (not smooth) muscle as it is under our conscious control. However, most of the time, we delegate control to the autonomic nervous system.

43. Which organs do NOT lie within a body cavity?

A. Heart

B. Brain and spinal cord

C. The muscles and bones of the legs

D. The prostate and urinary bladder

Answer is C: Each muscle and bone is an organ and the musculoskeletal system is within neither the dorsal nor ventral body cavities.

A. Pronation

B. Circumduction

C. Abduction

D. Rotation

Answer is C: Moving the straight arms away from the body in this fashion is called abduction.

45. What is meant by the term flexion (or to flex)?

A. Flexion is where the angle between two long bones is decreased by muscle action.

B. Flexion is an action performed to stretch (extend) a muscle.

C. Flexion is where the angle between two long bones is increased by muscle action.

D. Flexion is caused by the action of contracting a muscle

Answer is A: To flex an arm is to decrease the angle between the humerus and radius (by contracting the biceps brachii). Choice D is wrong as contracting the triceps brachii causes extension of the forearm.

46. To what movement is the term “extension” applied?

A. Extension is where the angle between two long bones is decreased by muscle action.

B. Extension is an action performed to stretch (extend) a muscle.

C. Extension is where the angle between two long bones is increased by muscle action.

D. Extension occurs when an antagonistic muscle is allowed to contract.

Answer is C: To extend a body part is to increase the angle between the moving bone and the stationary bone. For example when the fingers of a clenched fist are allowed to straighten, the angle between the proximal phalanges and the metacarpals increases.

47. What is the collective term used for the contents of the body’s ventral cavity?

A. The omentum

B. The peritoneum

C. The internal organs

D. The viscera

Answer is D: The peritoneum is the membrane that surrounds the abdominal cavity, and the omentum is a portion of that. The internal organs are close but also include the brain which is not in the ventral cavity.

48. What is meant by the term “retroperitoneal”?

A. On the dorsal side of the lungs.

B. In the space between the spinal cord and the bodies of the vertebrae.

C. Within the body wall but not enclosed by the peritoneum.

D. It is a small bone of the facial skeleton.

Answer is D: Retroperitoneal refers to organs inferior to the diaphragm but not enclosed by the peritoneum. For example the kidneys, pancreas, rectum and part of the duodenum.

49. What are the terms cortex and medulla used to describe?

A. The cortex is the outer part of an organ or bone while the medulla is the inner part.

B. The cortex is the inner part of an organ or bone while the medulla is the outer part.

C. The cortex is the deeper part of an organ or bone while the medulla is the more superficial part.

D. The medulla refers to the fibrous capsule around an organ, while the cortex is the tissue of an organ.

Answer is A: The cortex of the kidney, for example, is the deep (inner part) while the cortex is the more superficial, outer part.

50. What exists in the “potential space” between the visceral and parietal layers of a membrane?

A. Serous fluid

B. Nothing

C. Air

D. Synovial fluid

Answer is A: Serous membranes have a deeper visceral layer and a more superficial parietal layer. Between them is a small amount of serous fluid to lubricate their movement past each other.

51. One of the images taken for mammography of the compressed breast is known as “craniocaudal”. What direction is this?

A. Compression from the medial and lateral sides.

B. A left-to-right (sideways) view.

C. The breast is flattened against the rib cage for imaging.

D. When standing, the breast is compressed from above and below.

Answer is D: From above (the cranial direction) and below (the caudal or tail direction).

52. What is the collective name for the contents of our ventral cavity?

A. The giblets

B. The abdominopelvic organs

C. The internal organs

D. The viscera

Answer is D: The giblets is a term used for the internals of edible fowl such as chicken. The internal organs is close but also include the brain which is not in the ventral cavity. Abdominopelvic organs exclude the thoracic organs, which are in the ventral cavity.

53. What is/are the main function(s) of the serous membranes of the body’s ventral cavities and the potential space that is between their two layers?

A. To contain the enclosed organs and restrict them to their cavity.

B. To secrete a fluid which allows the organs and two layers to slide over each other without friction.

C. To secure the organs in position by attaching them to the skeleton.

D. To house the nerve supply and blood supply to the organs.

Answer is B: The serous fluid secreted allows the parietal membrane to slide over the visceral membrane without friction. This sliding occurs as we breathe walk and run and as food moves through the digestive tract. It also allows the organs to shift against their neighbour without friction. The membranes surround the organs and are attached to the body wall, so another function is to secure the organs to the body wall (so choice C is not wrong).

54. What is the clinical condition that develops when air is able to enter the “potential space” between the parietal and visceral pleura?

A. Pneumothorax

B. Pneumonia

C. Collapsed lung

D. Dyspnoea

Answer is A: Pneumo refers to air and thorax to the chest. Sometimes it is called collapsed lung, but atelectasis more correctly is applied to that. Dyspnoea refers to difficult or laboured breathing.

55. What is the clinical condition called when the membrane of the abdominal cavity is inflamed?

A. Meningitis

B. Pleurisy

C. Gastroenteritis

D. Peritonitis

Answer is D: The peritoneum is the membrane around the abdominal cavity. The suffix “-itis” is used to describe inflammation. Gastroenteritis describes the illness triggered by the infection and inflammation of the digestive system. Pleurisy refers to inflammation of the pleural membranes that surround the lungs. Meningitis refers to inflammation of the meninges that surround the brain and spinal cord.

56. Which organs do NOT have regions that are referred to as the cortex and the medulla?

A. Kidneys

B. Adrenals

C. Bones

D. Arteries

Answer is D: Medulla is the inner (deep) part of an organ while the cortex is the more superficial. Arteries walls are divided into “tunics” but do not have sections that are referred to as cortex or medulla.

57. Which of the following does the “tissue level” of structural organisation refer to?

A. Atoms, ions, molecules and electrolytes

B. Mitochondria, ribosomes, nucleus, endoplasmic reticulum

C. Nephron, alveolus, villus, lobule

D. Muscle, nervous, connective, epithelial

Answer is D: The listed structures are the four major tissue types.

58. How does an organ differ from a tissue?

A. An organ contains more than one type of tissue and performs a particular function.

B. An organ contains more than two types of tissues and performs a specialised function.

C. An organ contains more than three types of tissues and performs a relatively limited number of functions.

D. An organ contains more than four types of tissues and performs one or more specific functions.

Answer is A: “More than one type” implies at least two, and organs perform a function. The term specialised function is usually used for the work that tissue does. Choice D is wrong as there are only four main types of tissues. Choice C is wrong as more than three implies at least four, but the brain is an organ which does not contain any muscle tissue.

59. When a pianist is in a seated position with forearms making an angle of 90° with the arms, ready to play the piano, what would describe the position of her forearms?

A. Pronated

B. Supinated

C. Lateral to the abdomen

D. Medial to the thorax

Answer is A: To play the piano, the palms of the hands are facing the piano keys and the dorsal side of the hands are facing the ceiling. In this position, the forearms are in the pronated position.

60. The following is a list of several levels of organisation that make up the human body: (1) tissue; (2) cell; (3) organ; (4) molecule; (5) organism; (6) organ system. When listed in order from the smallest to the largest level, what sequence would the numbers be?

A. 2, 1, 4, 3, 6, 5

B. 4, 2, 1, 3, 6, 5

C. 4, 2, 1, 6, 3, 5

D. 4, 2, 3, 1, 6, 5

Answer is B: Molecule (4) must come first and organ system second to last. That eliminates A and C. Cell (2) and tissue (1) are next in increasing order and this coincides with choice B. 1 Organisation of the Body
