Which statement is true regarding the thyroid hormone and the thyroid-stimulating
hormone (TSH)?
A. Decreased anterior pituitary release of TSH stimulates its secretion.
B. TSH is secreted in excess when stimulated by thyroxine (T 4).
C. TSH secretion is regulated by thyrotropin-releasing
hormone. Correct
TSH secretion is regulated by thyrotropin-releasing hormone (TRH), primarily in
the hypothalamus and by negative feedback inhibition from thyroid hormones.
Increased anterior pituitary release of TSH stimulates the secretion of thyroid
hormones. TSH is inhibited by thyroxin (T4).
D. TSH secretion is controlled by positive feedback.

2. 2.ID: 18662100521
Obvious changes in cell function that are the result of stimulation by a particular
hormone describe which factor?
A. Up-regulation
B. Down-regulation
C. Direct effects Correct
Direct effects are obvious changes in cell function that are specifically
the result of stimulation by a particular hormone. Up-regulation
occurs when low concentrations of a hormone increase the number of
receptors per cell. Down-regulation occurs when high concentrations
of a hormone decrease the number of receptors. Permissive effects
are less obvious and facilitate the maximal response or functioning of
a cell.
D. Permissive effects

Which statement is true regarding the hypothalamus?
A. Is divided into numerous nuclei Correct
The hypothalamus is divided into numerous nuclei. The hypothalamus
is connected to the anterior pituitary by blood vessels and to the
posterior pituitary by a nerve tract. The hypothalamus is located at
the base of the brain.
B. Is connected to the anterior pituitary by a single membrane
C. Is connected to the posterior pituitary by blood vessels
D. Is located on the superior surface of the kidneys
