II. Physiology: Thermoregulation (heat dissipation)

  1. Increased skin blood flow
  2. Increased sweating with Evaporative Cooling

III. Type: Merocrine Sweat Gland (Merocrine secretion)

  1. Make up majority of bodies Sweat Glands
    1. Most concentrated in palms and soles
  2. Coiled tubular gland secretes watery fluid
    1. Sweat composed mainly of hypotonic Sodium chloride
    2. Released directly onto skin surface
  3. Innervatation
    1. Cholinergic fibers of Sympathetic Nervous System
  4. Stimulation of sweating
    1. Excessive body heat
    2. Fear

IV. Type: Apocrine Sweat Gland (Apocrine Secretion)

  1. Similar to odiferous glands in mammals
  2. Sweat Glands in axilla and genital regions
    1. Not functional until Puberty
    2. Function fluctuates with Menstrual Cycle in women
  3. Viscous secretions released via Hair Follicles
    1. Milky fluid often with odor due to skin flora
  4. Innervation
    1. Adrenergic fibers of Sympathetic Nervous System

Ontology: Eccrine Glands (C0013492)

Definition (NCI) An unbranched, coiled, tubular gland not associated with the hair follicle that promotes cooling by evaporation of its secretion. It is innervated by cholinergic nerve fibers.
Definition (NCI_NCI-GLOSS) A type of simple sweat gland that is found in almost all regions of the skin. These glands produce sweat that reaches the surface of the skin by way of coiled ducts (tubes). The body is cooled as sweat evaporates from the skin.
Definition (MSH) Simple sweat glands that secrete sweat directly onto the SKIN.
