Lesions of the ventromedial hypothalamic nucleus enhance sympatho-adrenal function. 1985

H Yoshimatsu, and Y Oomura, and T Katafuchi, and A Niijima, and A Sato

The effects of lesions of the ventromedial hypothalamic nucleus (VMH) on the sympatho-adrenal function were investigated in anesthetized rats using electrophysiological and biochemical techniques. Lesions of this nucleus produced a gradual but strong increase in the efferent activity of the adrenal sympathetic nerves. Catecholamine secretion from the adrenal medulla was also facilitated by VMH lesions. The results indicate that the catecholamines from the adrenal medulla might be involved in the development of metabolic disorders seen during VMH syndrome.

D009638 Norepinephrine Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D004837 Epinephrine The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.

D000311 Adrenal Glands A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS. Adrenal Gland,Gland, Adrenal,Glands, Adrenal
D000313 Adrenal Medulla 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. Adrenal Medullas,Medulla, Adrenal,Medullas, Adrenal
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
