Most exocrine glands are multicellular: goblet cells are examples of unicellular exocrine glands. The isthmus is usually located at the level of the second to third tracheal rings. In women, these glands are made up of lobes and lobules bound together by areolar tissue. They include the minor vestibular glands and the major vestibular glands (Bartholin glands). Any of the glands in the region of the anus. The whole gland is surrounded by a thin fibrous capsule attached in back to the cricoid cartilage and the first few tracheal rings. The gland is composed of two lobes, one on each side of the trachea, and an isthmus of tissue connecting the lower two thirds of each lobe. Synonym: PITUITARY GLAND: Hormones secreted by the anterior and posterior pituitary gland, along with target organs A small, gray, rounded gland that develops from ingrown oral epithelium (Rathke pouch) and is attached to the lower surface of the hypothalamus by the infundibular stalk.
Adrenocortical insufficiency may be acute or chronic; acute insufficiency of adrenal hormones produces circulatory shock, while chronic insufficiency results in Addison disease. The primary action of norepinephrine is constriction of the arterioles and venules, resulting in increased resistance to blood flow, elevated blood pressure, and slowing of the heart. A large endocrine gland located in the center of the base of the neck. The cells are arranged in cords. There are two main groups of glands: (1) The Organized aggregation of cells functioning as a secretory or excretory organ. Calcium is removed from bones, resulting in increased fragility. From Copstead, 1995.An organized aggregation of cells functioning as a secretory or excretory organ.An organized aggregation of cells functioning as a secretory or excretory organ. Any of the alveolar glands of the mucosa of the lips.The gland that secretes tears. Each of the 15 to 20 main ducts, known as lactiferous ducts, discharges through a separate orifice on the surface of the nipple. See: An endocrine gland in the brain, shaped like a pine cone and located in a pocket near the splenium of the corpus callosum. A multicellular gland in which the cells secrete specific molecules into a cylindrical sac.A lone secretory epithelial cell, often found in the midst of nonsecretory cells. Les cryptes de Lieberkühn, Cryptes du colon (ou glandes intestinales) sont des cellules caliciformes de l' épithélium de l' intestin grêle et du côlon, cellules qui s'invaginent sous forme de cryptes et qui sont des glandes exocrines tubuleuses droites. These hormones regulate the rate of cellular metabolism throughout the body. …depressions called intestinal glands, or Lieberkühn’s glands. The Rathke pouch portion forms the anterior lobe and an intermediate area; the neural tissue of the infundibular stalk forms the posterior lobe. A gland shaped like a single unbranched sac. Major clusters of endocrine tissue are also found in the gastrointestinal tract, the hypothalamus, the ovaries, the pancreas, the testes, and the placenta. The prostate consists of a median lobe and two lateral lobes measuring about 2 × 4 × 3 cm and weighing about 20 g; it is enclosed in a fibrous capsule containing smooth muscle fiber in its inner layer. A common example is the goblet (chalice, calceiform) cell, a unicellular mucous-secreting gland found in the columnar epithelium of the intestinal tract. The inner wall of the small intestine is covered by numerous folds of mucous membrane called plicae circulares. The medulla arises from ectoderm, which also gives rise to the sympathetic nervous system.The entire gland is enclosed in a tough connective tissue capsule from which trabeculae extend into the cortex. The medulla consists of chromaffin cells arranged in groups or in anastomosing cords.
Serous glands are most common in the gastrointestinal tract, notably in the salivary glands.
