are the adrenal glands in the abdomen?
446365
The adrenal glands are two small glands (each weighs about 4 to 6 grams) located in the back of the abdomen immediately above the kidneys. The adrenal glands make a variety of hormones that are essential to maintaining the normal function of the body.

The kidneys are inferior to the adrenal glands. True, the adrenal glands are above (superior) the kidneys.

Chromaffin cells of the adrenal medulla are innervated by the splanchnic nerve and secrete adrenaline (epinephrine), noradrenaline (norepinephrine), some dopamine, enkephalin and enkephalin-containing peptides, and a few other hormones into the blood stream.

Glucocorticoid, any steroid hormone that is produced by the adrenal gland and known particularly for its anti-inflammatory and immunosuppressive actions. The adrenal gland is an organ situated on top of the kidney. It consists of an outer cortex (adrenal cortex) and an inner medulla (adrenal medulla).

Adrenal glands. The adrenal glands are small structures attached to the top of each kidney. The human body has two adrenal glands that release chemicals called hormones into the bloodstream. These hormones affect many parts of the human body.

The adrenal glands are composed of two heterogenous types of tissue. In the center is the adrenal medulla, which produces adrenaline and noradrenaline and releases them into the bloodstream, as part of the sympathetic nervous system. Surrounding the medulla is the cortex, which produces a variety of steroid hormones.

Anatomy of the liver The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines.

The pancreas is located deep inside the abdomen. The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

The pancreas is a brownish, flattened gland found in the tissue between the stomach and small intestine. The pancreas produces digestive enzymes that are sent to the intestine via small ducts (the pancreatic duct). The pancreas also secretes insulin, which is important in the regulation of glucose metabolism.

It is a gland organ in the digestive and endocrine system. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as an exocrine gland, secreting pancreatic juice containing digestive enzymes that pass to the small intestine.

Kidneys. The kidneys are slightly protected by the ribs and are surrounded by fat for protection (not shown). On the superior aspect of each kidney is the adrenal gland.

The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.

The liver (under the ribcage in the right upper part of the abdomen), the gallbladder (hidden just below the liver), and the pancreas (beneath the stomach) are not part of the alimentary canal, but these organs are essential to digestion. The liver makes bile, which helps the body absorb fat.

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

The abdomen contains many vital organs: the stomach, the small intestine (jejunum and ileum), the large intestine (colon), the liver, the spleen, the gallbladder, the pancreas, the uterus, the fallopian tubes, the ovaries, the kidneys, the ureters, the bladder, and many blood vessels (arteries and veins).

The hormones of the adrenal medulla are the catecholamines, which also function as classical neurotransmitters in the autonomic nervous system. The adrenal medulla itself is modified neural tissue and its activity is regulated by a direct neural input. So the medulla functions like a modified sympathetic ganglion.

Endocrine glands are ductless glands and release the substances that they make (hormones) directly into the bloodstream. These glands form part of the endocrine system and information on them is included in this website. There is another type of gland called an exocrine gland (e.g. sweat glands, lymph nodes).
