The secretion of eccrine glands is a sterile, dilute electrolyte solution with primary components of bicarbonate, potassium, and sodium chloride (NaCl), and other minor components such as glucose, pyruvate, lactate, cytokines, immunoglobulins, antimicrobial peptides (e.g., dermcidin), and many others.
The lacrimal glands release their secretions directly onto the eyeball and are thus classified as serous type of exocrine glands with acini secretory elements. Lacrimal gland is an important part of the lacrimal apparatus (the lacrimal system) that plays an essential role in maintaining the normal anatomy of the eye.
Two unique types of cells are present in the parathyroid gland: Chief cells, which synthesize and release parathyroid hormone. These cells are small, and appear dark when loaded with parathyroid hormone, and clear when the hormone has been secreted, or in their resting state.
The pineal gland, also known as the conarium or epiphysis cerebri, is a small endocrine gland in the vertebrate brain. The pineal gland produces melatonin, a serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles.
Panhypopituitarism: It is due to decreased secretion of all the anterior pituitary gland hormones. It may be congenital (or) it may occur suddenly during the life of the individual. Dwarfism: It is due to deficiency of anterior pituitary gland secretion during childhood.
The submandibular glands (previously known as submaxillary glands) are a pair of major salivary glands located beneath the lower jaws, superior to the digastric muscles. The secretion produced is a mixture of both serous fluid and mucus, and enters the oral cavity via the submandibular duct or Wharton duct.
The thyroid gland is one component of the hypothalamic-pituitary-thyroid axis, which is a prime example of a negative feedback control system. The production and secretion of thyroxine and triiodothyronine by the thyroid gland are stimulated by the hypothalamic hormone thyrotropin-releasing hormone and the anterior pituitary hormone thyrotropin.
