Sex steroid hormones are not relased from the adrenal glands.
The adrenal glands are small endocrine glands that sit on top of the kidneys, they release adrenalin.
Sex steroid hormones are released from the interstitial cells in the testes in men and from the follicles in the ovaries in women.

In the pituitary gland
The sympathetic nervous system. The hypothalamus, in close association with the limbic system of the brain. The "fight or flight" response is the term used for the activation of the sympathetic nervous system. The two main chemicals invoved here are the neurotransmitter "norepinephrine" (noradrenaline) and the hormone "epinephrine" (adrenaline). Noradrenaline is produced in the neurones and is secreted at the synapse to exert its "sympathetic" activity on various organs throughout the body. The nervous system is also responsible for eliciting epinephrine production from the adrenal medulla (a part of the suprarenal glands situtated on the top of each kidney).
The pituitary gland controls the endocrine system.
When you are scared, the pituitary gland makes a mental note of it. It then processes the request to send a hormone (a chemical message) through the bloodstream to go to its "target center" which is the adrenal glands. the adrenal glands are located just above the kidneys in the lower abdomen area. Once these adrenal glands get this message; the hormone, it releases extra adrenaline into your bloodstream. the adrenaline affects all areas of your body, making you feel scared or nervous. Adrenaline in your system makes your senses sharper, and causes the "fight or flight" response. For ex. if you are watching a scary movie, and the slightest noise or touch is made outside of the movie, you might scream, thanks to adrenaline. If you are a protective mother, but run the car over your baby, sometimes you will get enough adrenaline to pick up the car and lift up your baby. {the side affect is becoming known as supermom. lol.} that is called the "fight response" because your muscles are using all the ATP (energy) and adrenaline, that it can do beyond human things like a "superhero" per say. If a bear is chasing you, adrenaline gives you the extra boost of energy to outrun the bear, faster than usual, and get away, saving your own life. this is known as the "Flight response". ~kthnx, hope that's helpful~ Krista xx <333
zona glomerulosa: mineralocorticoids
zona glomerulosa/mineralocorticoids
Adrenal glands are ductless in order to supply the secretion of hormones directly into the area requiring the levels. This bypasses the usage of a duct in order to regulate hormonal secretions.
zona glomerulosa/mineralocorticoids
A hypodense lesion at the right adrenal gland refers to an area that appears darker on imaging tests like CT scans, suggesting a lower density compared to surrounding tissue. This finding could indicate the presence of a mass, cyst, or hemorrhage in the adrenal gland. Further evaluation, such as additional imaging or biopsy, may be needed to determine the nature of the lesion.
The thyroid gland .
Primary aldosteronism, the symptoms of which include hypertension and low blood potassium (hypokalemia ), is considered "low-renin aldosteronism."
you shrink in your lower area :P
"Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the substantia nigra and the ventral tegmental area. The similarly melanin-pigmented cell bodies of the locus ceruleus produce norepinephrine." - WikipediaThe main catecholamines are epinephrine and norepinephrine, which are produced in the adrenal medulla (in the adrenal glands). Dopamine is the other, which is from neuronal cell bodies.
In the pituitary gland
Two endocrine glands are the hypothalamus gland and the Thyroid. The hypothalamus gland is located in the center area of the brain. It's functions are to stimulate and inhibit the release and secretion of the anterior pituitary gland. The thyroid gland is located around the esophageal area and it's functions are to release thyroxine and triiodothyronine, also know as t4 and t3 and calcitonin. The release of these hormones stimulate the energy metabolism of all cell and inhibits the breakdown of bone; causing a decrease in blood calcium concentraion.
Pheochromocytomas can be found anywhere chromaffin cells are found. They may be found in the heart and in the area around the bladder, but most (90%) are found in the adrenal glands
