Merocrine is the most common manner of secretion. The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine). The term eccrine is specifically used to designate merocrine secretions from sweat glands (eccrine sweat glands), [1] although the term merocrine is often used interchangeably. [2] [3]
Secretion is directly onto the apical surface. The glands in this group can be divided into three groups: Merocrine glands – cells secrete their substances by exocytosis. (e.g. mucous and serous glands; also called "eccrine", e.g. major sweat glands of humans, goblet cells, salivary gland, tear gland and intestinal glands)
The sebum also softens the hands. The secretion activity is related to hormonal release. If acne is occurring, it is because these gland ducts are blocked. Eccrine (merocrine) glands are most common. The secretions are very watery that contain some electrolytes; Apocrine glands produce a fatty secretion, thus giving away an odorous smell. These ...
Sweat glands were first separated into kinds by the French histologist Louis-Antoine Ranvier, who separated them in 1887 regarding their type of secretion into holocrine glands (sebaceous glands) and the merocrine glands (sweat glands), the latter were then in 1917 divided into apocrine and eccrine sweat glands. In 1987, apoeccrine glands were ...
The goblet cells mainly use the merocrine method of secretion, secreting vesicles into a duct, but may use apocrine methods, budding off their secretions, when under stress. [2] The term goblet refers to the cell's goblet-like shape. The apical portion is shaped like a cup, as it is distended by abundant mucus laden granules; its basal portion ...
The secretion of eccrine glands is a sterile, dilute electrolyte solution with primary components of bicarbonate, potassium, and sodium chloride (NaCl), [6] and other minor components that may include glucose, pyruvate, lactate, cytokines, immunoglobulins, antimicrobial peptides such as dermcidin, and many others.
During conventional protein secretion, proteins are transported through the ER-Golgi complex packaged in secretory granules and released to the extracellular space. Should invasive pathogens disrupt the Golgi apparatus , causing an impairment in the Paneth cell secretion of antimicrobial proteins, an alternative secretion pathway exists: it has ...
In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2–4 litres (0.5–1 US gal) per hour or 10–14 litres (2.5–3.5 US gal) per day, but is less in children prior to puberty.
