1. The origin of the term 'anatomy' is related to

• A. the Greek word for 'function.'
• B. the name of the first anatomist.
• C. the Greek word for 'cutting up.'
• D. the function of internal organs.

Correct answer: C

Rationale: The correct answer is C: the Greek word for 'cutting up.' The term 'anatomy' originates from the Greek words 'ana' (up) and 'temnein' (to cut), which means 'cutting up' or 'dissection.' This term refers to the process of dissecting bodies to study their structure. Choices A, B, and D are incorrect because 'anatomy' is not related to the Greek word for 'function,' the name of the first anatomist, or the function of internal organs, but rather to the act of cutting up for study and examination.

2. Lowering the hand by straightening the elbow affects which of the following muscles?

• A. biceps brachii
• B. triceps brachii
• C. brachialis
• D. brachioradialis

Correct answer: B

Rationale: Lowering the hand by straightening the elbow is the action of extending the forearm, which is primarily done by the triceps brachii muscle. The triceps brachii is the main extensor muscle of the elbow joint. The biceps brachii is responsible for flexing the elbow, not extending it, making it an incorrect choice. Brachialis is a strong elbow flexor, and brachioradialis helps in flexing the elbow and pronating the forearm, so they are not the primary muscles involved in straightening the elbow.

3. The muscular system is responsible for body movements, maintenance of posture, and production of body heat.

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. The muscular system is indeed responsible for body movements, maintenance of posture, and the production of body heat. Muscles contract and relax to allow movement, help in maintaining an upright posture, and generate heat through muscle activity. Choice B is incorrect because the functions mentioned are accurate. Choice C is incorrect as the functions of the muscular system are well-established. Choice D is incorrect as there is a correct answer among the options.

4. What is the term for the upper midportion of the abdomen?

• A. hypochondriac
• B. iliac
• C. hypogastric
• D. epigastric

Correct answer: D

Rationale: The correct answer is "epigastric." The epigastric region is located in the upper midportion of the abdomen, between the hypochondriac regions on either side. Choice A, "hypochondriac," refers to the upper lateral regions of the abdomen beneath the ribs. Choice B, "iliac," pertains to the lower lateral regions of the abdomen. Choice C, "hypogastric," is the lower central region of the abdomen.

5. Which of the following electrolytes plays an essential role in the clotting of blood?

• A. sodium
• B. magnesium
• C. calcium
• D. potassium

Correct answer: C

Rationale: Calcium plays an essential role in the clotting of blood by being involved in several steps of the coagulation process. It is necessary for the conversion of prothrombin to thrombin, which is a crucial step in forming blood clots. Sodium, magnesium, and potassium do not directly participate in the clotting cascade and are not associated with the coagulation process. Therefore, the correct answer is calcium.
