your system.
B) Endocrine messages tend to outlast the effects of neural messages.

21. At the age of 22, Mrs. LaBlanc was less than 4 feet tall. Her short stature was probably
influenced by the lack of a growth hormone produced by the
A) pancreas.
B) thyroid.
C) adrenal gland.
D) pituitary gland.
E) myelin.
22. At puberty, the hypothalamus secretes gonadotropin-releasing hormones (GnRH), causing the
secretion of gonadotropins by the pituitary gland. These hormones cause the ovaries to produce
estrogen and testes to produce testosterone. As the levels of these hormones rise, they shut
down the release of GnRH and the gonadotropins. This example illustrates the
A) feedback systems connecting the brain and endocrine systems.
B) information highway connecting the peripheral nervous system to the brain.
C) role of agonists and antagonists in the nervous system.
D) reflex pathways running through the spinal cord.
E) combined signals of excitatory and inhibitory connections.
