Sudomotor (lat. sudor = sweat + motor) is a medical term used to describe something that stimulates the sweat glands.
Sudomotor Innervation may refer to the cholinergic innervation of the sympathetic nervous system prominent in sweat glands which causes perspiration to occur via activation of muscarinic acetylcholine receptors.
example : injury of the autonomic part of peripheral nerve causes sudomotor changes as loss of sweating .
