Psychological sweating: a systematic review focused on
SpletSweating is caused by the activation of sympathetic sudomotor nerves innervating eccrine sweat glands, which cover most of the body surface. These nerves release acetylcholine, which interacts with muscarinic cholinergic receptors at the sweat gland and triggers the onset of sweating. Splet07. jan. 2024 · All postganglionic fibers of the sympathetic division are adrenergic fibers (release norepinephrine) that act on adrenergic alpha or beta receptors for neurotransmission, with the exception of the fibers innervating the sweat glands, which are cholinergic. The adrenal medulla does not have a postsynaptic neuron. organ retrieval anaesthesia
Innervation of Sweat Glands and Control of Sweating
SpletCholinergic innervation is the primary effector eliciting activation of eccrine sweat glands during periods of acute psychological stress. A dual innervation pathway for eccrine … Eccrine sweat glands are the major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the torso and the extremities. In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads. They reach their peak of development in humans, where they may number 200–400/cm of skin surface. They produce a clear, odorless substance, sweat, consisting primar… SpletVery few parts of the sympathetic system use cholinergic receptors. In sweat glands the receptors are of the muscarinic type.
