| umls-concept:C0001629 | skos:definition | MSH: The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.,CSP: inner part of the adrenal gland; it synthesizes, stores and releases catecholamines.,NCI: The inner part of the adrenal gland (a small organ on top of each kidney). The adrenal medulla makes chemicals such as epinephrine (adrenaline) and norepinephrine (noradrenaline) which are involved in sending nerve signals.,NCI: The inner part of the adrenal gland; it synthesizes, stores and releases catecholamines.
