The endocrine cell can also secrete hormones that target cells directly close it. When this occurs,

The posterior pituitary receives its hormones (oxytocin and ADH) from the hypothalamus. The a

ADH is the only hormone listed that is produced by the hypothalamus. The

rmones are signaling molecules. Although a wide variety of hormones function within the body,
n n n n n n n n n n n n n n
they share certain general characteristics:
n n n n
1. Hormones have speci昀椀 n n
c rates and rhythms of secretion. Three basic secretion patterns are: (1) circadian or diurnal
n n n n n n n n n n n n n n
patterns, (2) pulsatile and cyclic patterns, and (3) patterns that depend on levels of circula
n n n n n n n n n n n n n n n
ting substrates (e.g., calcium, sodium, potassium, or the hormones themselves).
n n n n n n n n n
2. Hormones operate within feedback systems, either positive or negative, to maintain an op

timal internal environment. n n
3. Hormones affect only cells with speci昀椀 n n n n n
c receptors and then act on those cells to initiate speci昀椀c cell functions or activities.
n n n n n n n n n n n n n n
When an endocrine cell receives a stimulus or command, this stimulates the endocrine cell to sec
n n n n n n n n n n n n n n n
rete hormones into the blood stream. The hormones will then target and bind onto a

speci昀椀
c receptor on a target cell. This will cause the target cell to initiate a response as shown in the diag
