Adrenal Glands
There are two adrenal glands located above the kidneys. They are triangular in shape and are composed of two parts:
1) cortex: which is the outer layer of the gland (if you sliced through it and looked at a cross section).
2) medulla: the interior of the cross section. This part functions to secrete epinephrine and norepinephrine (determines fight or flight)
-The adrenal glands also synthesize cortisol (a steroid released in response to stress and low FSBS)
-
Addison's Disease
A condition in which there is chronic deficiency of the adrenal cortex.
Sx's include: fatigability, weakness, weight loss, loss of appetite, nausea, vomiting, emotional instability, discoloration of skin
-
Cushing's disease
Excessive production of the hormone of the adrenal cortex.
Sx's: redistribution of fat to the upper torso, neck and shoulders (giving a buffalo appearance). A fattened round moon face, purplish streaks in the skin of abd., thighs, and arms. Development of male body characteristics, HTN, high FSBS.
-
Conn's Syndrome
Caused by tumors of the adrenal glands which manifacture a specialized hormone.
Sx's: various (weakness, paralysis, excessive thirst, excessive urination, HA), but mostly include HTN.
