1. An anatomical section that separates the body into right and left portions is a _______ section.

• A. frontal
• B. transverse
• C. coronal
• D. sagittal

Correct answer: D

Rationale: The correct answer is 'sagittal.' A sagittal section divides the body into right and left portions. Choice A, 'frontal,' is incorrect as it divides the body into front and back portions. Choice B, 'transverse,' divides the body into upper and lower portions. Choice C, 'coronal,' divides the body into anterior and posterior portions. Therefore, 'sagittal' is the most appropriate term for a section separating the body into right and left portions.

2. 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.

3. Which of the following is a result of stimulation of the sympathetic nervous system?

• A. decreased blood flow to the skeletal muscles
• B. increased cardiac output
• C. decreased respiratory rate
• D. increased urinary output

Correct answer: B

Rationale: Stimulation of the sympathetic nervous system leads to an increase in cardiac output. When the sympathetic nervous system is activated, it causes the heart to beat faster and with more force, leading to an increased cardiac output. Choices A, C, and D are incorrect because the sympathetic nervous system does not cause decreased blood flow to the skeletal muscles, decreased respiratory rate, or increased urinary output.

4. An occurrence of too high a concentration of which of the following electrolytes is associated with cardiac arrhythmias?

• A. chloride
• B. phosphorus
• C. potassium
• D. sodium

Correct answer: C

Rationale: The correct answer is potassium. High levels of potassium in the blood, known as hyperkalemia, can lead to cardiac arrhythmias by affecting the electrical activity of the heart. This can disrupt the normal rhythm of the heart and lead to serious complications. Chloride, phosphorus, and sodium imbalances are not typically associated with cardiac arrhythmias, making them incorrect choices.

5. Does aging begin in the fetus?

• A. Yes
• B. No
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: Aging does begin in the fetus. The aging process starts even before birth due to cellular changes and the passage of time. The cells in a fetus undergo growth, division, and aging from the moment of conception. This continual process of cellular aging continues throughout life. Therefore, the statement is true. Choice B is incorrect because aging does initiate during the fetal stage. Choice C is incorrect as the process of aging commences in the fetus. Choice D is incorrect as the correct answer is 'Yes,' indicating that aging does start in the fetus.
