Endoscopic thoracic sympathectomy (ETS) refers to surgical interruption of the sympathetic nerves responsible for sweating. Sympathectomy is an operation intended to destroy part of the nerve supply to the sweat glands in the skin. The surgeon inserts a special endoscopic instrument into the chest between two ribs just below the armpit. The.
Sweat gland definition is - a simple tubular gland of the skin that excretes perspiration, is widely distributed in nearly all parts of the human skin, and consists typically of an epithelial tube extending spirally from a minute pore on the surface of the skin into the dermis or subcutaneous tissues where it ends in a convoluted tuft.
Basically, the sweat gland is a long, coiled, hollow tube of cells.The coiled part in the dermis is where sweat is produced, and the long portion is a duct that connects the gland to the opening or pore on the skins's outer surface. Nerve cells from the sympathetic nervous system connect to the sweat glands. There are two types of sweat glands.
The nerve fibers that surround sweat gland tubules are primarily sympathetic cholinergic (Fig. 85.2A,C), although some sympathetic adrenergic and sensory fibers are present (Fig. 85.2D). In addition to a dense network of nerve fibers, there are also a large number of capillaries within sweat glands that have separate innervation ( Fig. 85.2B ).
The sweat glands are innervated by the sympathetic nervous system and are part of the fight or flight response system. Their innervation consists of two parts, a preganglionic and postganglionic neuron. The preganglionic neuron is short, originates from the thoracolumbar region of the spinal cord, uses acetylcholine as its neurotransmitter, and synapses with the postganglionic neuron via a.
Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor, meaning 'sweat', (6) (7) are small tubular structures of the skin that produce sweat.Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct.There are two main types of sweat glands that differ in their structure, function.

Eccrine sweat glands and their sympathetic innervation develop together postnatally in the rat. Early postnatal innervation expresses only noradrenergic properties, but as the glands and their.
