Student Answer:
inside the plasma membrane in the cytoplasm.
on the outer surface of the plasma membrane.
inside the mitochondria.
on the inner surface of the plasma membrane.

Question 2. Question : Where is oxytocin synthesized?
Student Answer:
Hypothalamus
Paraventricular nuclei
Anterior pituitary
Posterior pituitary
Instructor The posterior pituitary secretes two polypeptide hormones: (1) ADH, also called
Explanation: arginine vasopressin; and (2) oxytocin.

Question 3. Question : A surgical individual just arrived on the unit from the postanesthesia
care unit. This person’s respirations are 4 per minute and shallow. As
the nurse calls for assistance, the person suddenly feels jittery and
breathing quickens. Which of the following feedback loops is operating
for the nurse in this situation?
Student Answer:
The central nervous system stimulates hypothalamus-releasing
factor, which acts on the anterior pituitary gland to secrete thyroid-
stimulating hormone (TSH) and stimulates the release of thyroxine (T 4)
and triiodothyronine (T3).
The central nervous system directly stimulates the release of
insulin, which reduces blood glucose levels.
, NR507 Week 5 Quiz.
The central nervous system directly stimulates the adrenal
medulla to secrete epinephrine and stimulates hypothalamus-releasing
factor, which acts on the anterior pituitary gland to secrete
adrenocorticotropic-stimulating hormone (ACTH), stimulating the
release of cortisol.
The central nervous system stimulates the hypothalamus to
synthesize oxytocin and antidiuretic hormone, which are secreted by
the posterior pituitary, activating uterine contraction and renal
absorption of water.
Instructor The secretion of cortisol is regulated primarily by the hypothalamus and the
Explanation: anterior pituitary gland. In the hypothalamus, corticotropin-releasing
hormone (CRH) is produced in several nuclei and stored in the median
eminence. Once released, CRH travels through the portal vessels to
stimulate the production of ACTH from pro-opiomelanocortin (POMC), -
lipotropin, -lipotropin, endorphins, and enkephalins by the anterior
pituitary. ACTH is the main regulator of cortisol secretion and adrenocortical
growth.
