Gland

See also Gland (homonymy)

A gland is a body of the animal or Plante S which synthesizes a substance which will be secreted. The released substance can have a role in the intercellular communication, like the Hormone S and will then be emitted in circulation Sang uine (one speaks about endocrine Gland). The glands can also produce substances which will be released in body cavities, or outside (Glande exocrine, Nectaire of the Fleur S, etc).

Process of secretion for glands exocrines: mérocrine: form most current, is done by exocytose (channel joining gland) apocrine: expulsion of free blisters (glands mammaires and glands sudoripares) holocrine: explosion of the cell (sébacées glands)

The Homme has a large variety of glands, Hypophyse in the Cerveau with the glands sudoripares dispersed on the Peau which release the Sueur to regulate the body temperature. Among other notorious glands, one can quote the Surrénale S, the gland prostate sufferer, the thyroid gland, the pineal Body, the Thymus and the gland mammaire. Two other paired glands are the parotid glands and the glands submandibulaires, both implied in the production of Salive.

In the animals, varied glands produce Phéromone S marking the passage or the territory of the animal or a group. The Glande uropygienne makes it possible the birds to waterproof and protect their plumage. At the terrestrial gastropods (Escargot S, Limace S. and many invertebrates, external glands produce a Mucus which protect them). In certain Amphibians (Frog S, Clamping plate S, salamander S. mucus can contain Alcaloïde S Neurotoxique S, sometimes mortals or Hallucinogène S at certain species).
