[Catecholamine-containing sympathetic spinal neurons innervating the feline heart]. 1989

A Kh Kade, and T P Perova, and M G Shubich, and V M Pokrovskiĭ

The present study determined that a population "nonclassical" sympathetic neurons in cats spinal cord contains catecholamines. They are localized in the central, dorsomedial, and lateral regions of the ventral horn of T1-T5 segments of the spinal cord. Electrophysiological study indicated that axonal conduction velocity is 7.3 +/- 0.5 m/s (ranging from 3.6 to 17.2 m/s). Possible functional roles of catecholamine-containing neurons of spinal cord include involvement in sympathetic control of cardiac cycle duration.

UI	MeSH Term	Description	Entries
D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D011412	Propanolamines	AMINO ALCOHOLS containing the propanolamine (NH2CH2CHOHCH2) group and its derivatives.	Aminopropanols
D002395	Catecholamines	A general class of ortho-dihydroxyphenylalkylamines derived from TYROSINE.	Catecholamine,Sympathin,Sympathins
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D005730	Ganglionic Blockers	Agents having as their major action the interruption of neural transmission at nicotinic receptors on postganglionic autonomic neurons. Because their actions are so broad, including blocking of sympathetic and parasympathetic systems, their therapeutic use has been largely supplanted by more specific drugs. They may still be used in the control of blood pressure in patients with acute dissecting aortic aneurysm and for the induction of hypotension in surgery.

D006321	Heart	The hollow, muscular organ that maintains the circulation of the blood.	Hearts
D000319	Adrenergic beta-Antagonists	Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are used for treatment of hypertension, cardiac arrhythmias, angina pectoris, glaucoma, migraine headaches, and anxiety.
