Information about Endocrine Glands

gland is an organ in an animal's body that synthesizes a substance for release such as hormones, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland).

Exocrine glands are glands that secrete their products (enzymes) into ducts (duct glands). They are the counterparts to endocrine glands, which secrete their products (hormones) directly into the bloodstream (ductless glands).

Merocrine (eccrine) is a classification of exocrine glands in the study of Histology.

A cell is classified as merocrine if the secretions of that cell dump directly into the lumen.

Apocrine is a term used to classify exocrine glands in the study of histology. Cells which are classified as apocrine bud their secretions off through the plasma membrane producing membrane bound vesicles in the lumen.

Holocrine is a classification of exocrine glands in the study of Histology.

Holocrine secretions are produced within the cell followed by the rupture of the plasma membrane, thus releasing the cellular contents into the lumen.

If a gland retains its shape as a tube throughout it is termed a tubular gland.^{[1] [2]}

Tubular glands are further classified as one of the following:

Serous glands contain serous acini, a grouping of serous cells that secrete a fluid, isotonic with blood plasma, that contains enzymes such as alpha amylase.

Serous glands are most common in the parotid gland, but are also present in the submandibular gland and, to a far

Mucous glands, found in several different parts of the body, typically stain lighter than serous glands during standard histological preparation. Most are multicellular, but goblet cell are single-celled glands.

A serous demilune is a cap in the shape of a half-moon (hence the name, "demilune") on some salivary glands.

The serous demilune is an artifact from traditional methods of preparing samples. Samples are traditionally preserved and fixed in formaldehyde.

In anatomy and physiology, a duct is a circumscribed channel leading from an exocrine gland or organ.

Types of ducts

Examples include:

Duct From To Carries
Lactiferous duct mammary gland nipple milk

A interlobar duct is a gland duct which connects more than one anatomic lobe.

Examples of where it can be found include the parotid gland^[1] and submandibular gland.

A Interlobular duct is a gland duct which connects more than one lobule. It is smaller than an interlobar duct.

Examples of where it can be found include

• pancreas^[1][2]
• mammary gland^[3]
• parotid gland^[4][5]

An intralobular duct is the portion of an exocrine gland inside a lobule, leading directly from intercalated duct to an interlobular duct.

They can be seen in:

• pancreas^[1][2][3][4]
• salivary glands^[5]

A striated duct is a gland duct which connects an intercalated duct to an interlobular duct. It is characterized by its folded membrane.^{[1] [2]}

Their epithelium can be simple cuboidal or simple columnar.

The intercalated duct is the portion of an exocrine gland leading directly from the acinus, and to a striated duct.

They are part of the intralobular duct.

They have the thinnest epithelium of any part of the duct system, and the epithelium is usually classified as

An acinus (adjective: acinar, plural acini) refers to the berry-shaped termination of an exocrine gland, where the secretion is produced.

They are found in many organs, including:

• the stomach^[1]
• the sebaceous gland of the scalp

The endocrine system

The hypothalamus links the nervous system to the endocrine system via the pituitary gland (hypophysis). The hypothalamus, (from Greek ὑποθαλαμος = under the thalamus) is located below the thalamus, just above the brain stem.

The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea that sits in a small, bony cavity (sella turcica) covered by a dural fold (sellar diaphragm) at the base of the brain.

The hypothalamic-pituitary-adrenal axis (HPA axis) is a complex set of direct influences and feedback interactions between: the hypothalamus, a hollow, funnel-shaped part of the brain; the pituitary gland, a pea-shaped structure located below the hypothalamus; and the

In mammals, the adrenal glands (also known as suprarenal glands) are the triangle-shaped endocrine glands that sit on top of the kidneys; their name indicates that position (ad-, "near" or "at" + -renes, "kidneys").

The hypothalamic-pituitary-thyroid axis (HPT axis for short) is part of the endocrine system responsible for the regulation of metabolism.

As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland.

The thyroid is one of the largest endocrine glands in the body. This gland is found in the neck just below the laryngeal prominence.

The parathyroid glands are small endocrine glands in the neck, usually located behind the thyroid gland, which produce parathyroid hormone. In rare cases the parathyroid glands are located within the thyroid glands.

The hypothalamic-pituitary-gonadal axis (also HPTA) is a way of referring to the combined effects of the hypothalamus, pituitary gland, and gonads as if these individual endocrine glands were a single entity.
