TEAS version 7 quizlet science
1. What is the outermost protective layer of the kidney?
- A. Renal cortex
- B. Renal medulla
- C. Renal capsule
- D. Renal pelvis
Correct answer: C
Rationale: The correct answer is C, Renal capsule. The renal capsule is the outermost protective layer of the kidney. It is a tough fibrous layer that surrounds the kidney and helps protect it from injury and maintain its shape. Choice A, Renal cortex, is the outer region of the kidney where filtration occurs. Choice B, Renal medulla, is the inner region of the kidney where urine is formed. Choice D, Renal pelvis, is the funnel-shaped structure that collects urine from the kidney and funnels it into the ureter. Therefore, the renal capsule is specifically designated as the outermost protective layer of the kidney.
2. What is surgically altered during a vasectomy?
- A. Vas deferens
- B. Glans penis
- C. Prostate
- D. Urethra
Correct answer: A
Rationale: During a vasectomy, the vas deferens is surgically altered or cut to prevent the transport of sperm from the testicles to the urethra. This procedure is a form of permanent male sterilization. The glans penis, prostate, and urethra are not surgically altered during a vasectomy. Therefore, the correct answer is the vas deferens (Choice A), as it is the structure specifically targeted and modified in this procedure. The glans penis (Choice B) is the sensitive tip of the penis, the prostate (Choice C) is a gland vital for semen production but not involved in a vasectomy, and the urethra (Choice D) is the tube that carries urine and semen but is not surgically altered in a vasectomy.
3. What is the function of the pons?
- A. Center for emotion and motivation
- B. Control production of hormones
- C. Relay messages from the cortex to the cerebellum
- D. Responsible for involuntary actions like breathing
Correct answer: C
Rationale: The correct function of the pons is to relay messages from the cortex to the cerebellum. The pons acts as a bridge between different brain regions, facilitating communication and coordination of movements. Choices A, B, and D are incorrect. The pons is not the center for emotion and motivation, does not control hormone production, and is not primarily responsible for involuntary actions like breathing. Understanding the role of the pons in relaying messages between brain regions is crucial for comprehending its function in the central nervous system.
4. Which term refers to a position toward the feet? For example, the foot is part of the inferior extremity.
- A. Anterior
- B. Posterior
- C. Superior
- D. Inferior
Correct answer: D
Rationale: The correct answer is 'Inferior.' 'Inferior' refers to a position located towards the feet or lower part of the body. This is the opposite of 'superior,' which indicates a position towards the head or upper part of the body. 'Anterior' refers to the front of the body, 'posterior' refers to the back of the body, making them incorrect choices in this context.
5. What is meant by the term 'goiter'?
- A. Overproduction of cortisol from the adrenal glands
- B. Excessive growth of the thyroid gland
- C. Underproduction of parathyroid hormone (PTH)
- D. Deficiency of growth hormone from the pituitary gland
Correct answer: B
Rationale: A goiter is a condition characterized by the abnormal enlargement of the thyroid gland. This enlargement can be caused by various factors such as iodine deficiency, thyroid nodules, inflammation, or other thyroid disorders. It is not associated with the overproduction of cortisol (Choice A), underproduction of parathyroid hormone (Choice C), or deficiency of growth hormone (Choice D). Therefore, the correct answer is B, excessive growth of the thyroid gland.
