Adrenal Gland Histology Adrenal Cortex -- the outer, firm layer comprising the larger part of the adrenal gland; it secretes many steroid hormones including mineralocorticoids, glucocorticoids, androgens, 17-ketosteroids, and progestins. Adrenal medulla: The inner portion of adrenal gland. (The outer portion is the adrenal cortex). The adrenal medulla makes epinephrine (adrenaline) and norepinephrine (noradrenaline).

Neuroscientists have identified the neural networks that connect the cerebral cortex to the adrenal medulla, which is responsible for the body's rapid response in stressful situations. These findings provide evidence for the neural basis of a mind-body connection. Specifically, the findings shed new light on how stress, depression and other mental states can alter organ function, and show that there is a real anatomical basis for psychosomatic illness.
Pheochromocytoma. A tumor of the adrenal gland that secretes catecholamines (norepinephrine, epinepherine, dopamine) in various proportions. 90% of the tumors occur in the adrenal medulla, but could be located in various other places around the body. Considered benign if it has not invaded the capsule or metastasized. Manifestations: paroxysmal hypertension in 45% of parients, tachycardia, diaphoresis, postural hypotension, tachypnea, cold and clammy skin, headache, angina, nausea.
Opening the 7 Chakras: 1) Earth -- Base of Spine, Muladhara; Survival, blocked by Fear, open by surrendering to Fears. Endocrine System: associated with the gonads and the adrenal medulla, responsible for the fight-or-flight response when survival is under threat.
