The sympathoadrenal system is a physiological connection between the sympathetic nervous system and the adrenal medulla and is crucial in an organism's physiological response to outside stimuli. [1] When the body receives sensory information, the sympathetic nervous system sends a signal to preganglionic nerve fibers, which activate the adrenal ...
The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. [1][2] They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla.
Testosterone is the primary male sex hormone and androgen in males. [ 3 ] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
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]
Anatomical terminology. [edit on Wikidata] The endocrine system[1] is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems.
Stress hormones are secreted by endocrine glands to modify one's internal environment during the times of stress. [1] By performing various functions such as mobilizing energy sources, increasing heart rate, and downregulating metabolic processes which are not immediately necessary, stress hormones promote the survival of the organism. [1] The ...
Androgens are synthesized from cholesterol and are produced primarily in the gonads (testicles and ovaries) and also in the adrenal glands. The testicles produce a much higher quantity than the ovaries. Conversion of testosterone to the more potent DHT occurs in prostate gland, liver, brain and skin. v.
Corticotropin-releasing hormone (CRH) (also known as corticotropin-releasing factor (CRF) or corticoliberin; corticotropin may also be spelled corticotrophin) is a peptide hormone involved in stress responses. It is a releasing hormone that belongs to corticotropin-releasing factor family. In humans, it is encoded by the CRH gene. [5]
