glomus body , auch: glomus organ

Glomus bodies are most numerous in the fingers and toes.

The glomus body has high sympathetic tone and potentiation leads to near complete vasoconstriction.

The glomus cell is not to be confused with the glomus body found in the dermis layer of the skin.

The glomus body consists of an arterio-venous shunt surrounded by a capsule of connective tissue.

A glomus body (or glomus apparatus) is a component of the dermis layer of the skin, involved in body temperature regulation.

A glomectomy is an excision of a glomus body or a glomus cell, usually in the case of a glomus tumor.

At or below 0 C (32 F), blood vessels close to the skin start to constrict, and blood is shunted away from the extremities via the action of glomus bodies.

The role of the glomus body is to shunt blood away from the skin surface when exposed to cold temperature, thus preventing heat loss, and allowing maximum heat flow to the skin in warm weather to allow heat to dissipate.

A glomus tumor (also known as a "solitary glomus tumor," "solid glomus tumor," or glomangioma) is a rare benign neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot.
