Which statement about growth hormone or its function is true?
A) Growth hormone stops being produced just prior to birth.

E) Growth hormone is produced in the posterior pituitary gland.

Question

Quizplus · Accepted Answer

This statement is true. Growth hormone is released from the anterior pituitary gland in response to the stimulation of neurohormones produced by the hypothalamus. Specifically, growth hormone releasing hormone (GHRH) stimulates the release of growth hormone, while somatostatin inhibits its release.

Note: A is false as growth hormone is actually secreted at high levels during the first few years after birth. B is also false as underproduction of growth hormone can lead to pituitary dwarfism, while overproduction can lead to gigantism. C is false as hormone therapy can be used to treat pituitary dwarfism by replacing the deficient growth hormone. E is also false as growth hormone is produced and released from the anterior pituitary gland, not the posterior pituitary gland.
