adrenal gland

n.
Either of two small, dissimilarly shaped endocrine glands, one located above each kidney, consisting of the cortex, which secretes several steroid hormones, and the medulla, which secretes epinephrine. Also called suprarenal gland.

adrenal gland

n
(Anatomy) an endocrine gland at the anterior end of each kidney. Its medulla secretes adrenaline and noradrenaline and its cortex secretes several steroid hormones. Also called: suprarenal gland

adre′nal gland`


n.
one of a pair of ductless glands, located above the kidneys, consisting of a cortex, which produces steroidal hormones, and a medulla, which produces epinephrine and norepinephrine.

Cannon, the physiologist who first described changes in adrenal gland secretion in response to threats to homeostasis, including "exposure to cold, traumatic pain," and "emotionally distressing antagonistic encounters." Today, the scientific community continues to identify stress as any perceived threat to homeostasis, which is a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
[ClickPress, Mon Oct 08 2018] Addison's disease is a hormonal disorder characterized by inadequate secretion of certain hormones such as cortisol (glucocorticoid) and aldosterone (mineralocorticoid) by adrenal gland. Cortisol manages glucose level and is also helpful in suppressing immune response.
Trilostane blocks the enzymes involved in the production of Cortisol in the adrenal gland cortex, inhibiting the production of Cortisol.
