  2. Adrenaline - Wikipedia

    en.wikipedia.org/wiki/Adrenaline

    Adrenaline, also known as epinephrine, is a hormone and medication [10] [11] which is involved in regulating visceral functions (e.g., respiration). [10] [12] It appears as a white microcrystalline granule. [13] Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata. [14]

  3. Adrenal gland - Wikipedia

    en.wikipedia.org/wiki/Adrenal_gland

    The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress situations. [4] A number of endocrine diseases involve dysfunctions of the adrenal gland. Overproduction of cortisol leads to Cushing's syndrome, whereas insufficient production is associated with Addison's disease.

  4. Catecholamine - Wikipedia

    en.wikipedia.org/wiki/Catecholamine

    Catecholamines are secreted by cells in tissues of different systems of the human body, mostly by the nervous and the endocrine systems. The adrenal glands secrete certain catecholamines into the blood when the person is physically or mentally stressed and this is usually a healthy physiological response.

  5. Adrenal medulla - Wikipedia

    en.wikipedia.org/wiki/Adrenal_medulla

    In dopamine beta hydroxylase deficiency, the entire body cannot efficiently produce epinephrine and norepinephrine from dopamine, this results in severe dysautonomia but most crucially due to autonomous nervous system failure which requires epinephrine and norepinephrine as neurotransmitters, dopamine being used in this pathology as an ...

  6. Sympathoadrenal system - Wikipedia

    en.wikipedia.org/wiki/Sympathoadrenal_system

    Glucose, a necessary source of energy for cells, can undergo an increase in production due to elevated secretion of epinephrine in the body. The mechanism lies in epinephrine being secreted by the adrenal medulla and activating glycogenolysis (the breakdown of glycogen into glucose, or promoting gluconeogenesis (glucose formation). While ...

  7. List of human hormones - Wikipedia

    en.wikipedia.org/wiki/List_of_human_hormones

    The following is a list of hormones found in Humans. Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.

  8. Chromaffin cell - Wikipedia

    en.wikipedia.org/wiki/Chromaffin_cell

    Chromaffin cells, also called pheochromocytes (or phaeochromocytes), are neuroendocrine cells found mostly in the medulla of the adrenal glands in mammals.These cells serve a variety of functions such as serving as a response to stress, monitoring carbon dioxide and oxygen concentrations in the body, maintenance of respiration and the regulation of blood pressure. [1]

  9. Endocrine gland - Wikipedia

    en.wikipedia.org/wiki/Endocrine_gland

    The endocrine system is a network of glands and organs located throughout the body. It is similar to the nervous system in that it plays a vital role in controlling and regulating many of the body's functions. Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood.
