Pancreatic islets The islet density routes throughout the healthy human pancreas. The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells, discovered in 1869 by German pathological anatomist Paul Langerhans.

Endocrine gland (January 2010) Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.

- Topics | Endocrine System | What is the function of islets in the pancreas? Islets are groups of cells located in the pancreas that make hormones that help the body break down and use food. For example, alpha cells make glucagon and beta cells make insulin. They are also called islets of Langerhans.

Pancreas: Functions, Anatomy & Insulin Production Insulin is produced inside the islets of Langerhans, named after their discoverer. Insulin is a hormone that lowers blood sugar levels. It is good to note that it would be equally correct to say that it's a hormone that lowers blood glucose levels.

Exocrine gland The liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products— bile and pancreatic juice —into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream.xocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. 1  The duct portion may be branched (called compound) or unbranched (called simple).

- 1 Hormones produced in the islets of Langerhans are secreted directly into the blood flow by at least five different types of cells.  The hormones produced in the islets of Langerhans area of the pancreas are insulin, glucagon, and somatostatin.

Medical Definition of Endocrine gland They include the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroid glands, heart (which makes atrial-natriuretic peptide), the stomach and intestines, islets of Langerhans in the pancreas, the adrenal glands, the kidney (which makes renin, erythropoietin, and calcitriol), fat cells (which make leptin). the testes, the ovarian follicle and the corpus luteum in the ovary).

- The parathyroid glands are small endocrine glands in the neck of humans and other tetrapods that produce parathyroid hormone. Humans usually have four parathyroid glands, variably located on the back of the thyroid gland, although considerable variation exists.

Overview of Adrenal Histology Overview of Adrenal Histology. The adrenal gland is encased in a connective tissue capsule that extends septae into the substance of the gland. The organ is richly vascularized and capsular blood vessels, nerves and lymphatics penetrate along with the connective tissue septae. The most distinctive feature of the adrenal is its partitioning into cortex and medulla.

- The hormones made by the cells in the islets of Langerhans within the pancreas include: Insulin - which helps to regulate sugar levels in the blood. Glucagon - which works with insulin to keep blood sugar levels balanced. Somatostatin - which helps to control the release of other hormones.

- There are two major components of any exocrine gland: Parenchyma, which is the epithelial component of the gland consisting of the secretory units and ducts. Stroma, which is the connective tissue component of the gland (for support), as well as blood vessels and nerves.

- In the pancreas, part of the organ is an exocrine gland (the acini) secreting and part is endocrine , i.e., the islets of Langerhans which secrete various hormones such as insulin and glucagon. In the digestive system, some cells are endocrine cells, i.e., the enteroendocrine cells. Other endocrine organs include the thyroid, parathyroid, adrenal, and pituitary gland. The thyroid gland is located dorsolateral to the trachea, close to the larynx. It has two lobes that are connected by a narrow isthmus.

Pancreatic Islets of Langerhans; Adrenal gland Delta cells make up 5% of the pancreatic cells in the Islets of Langerhans and are located variably in the area and release somatostatin, produce somatostatin, which acts within the islets of Langerhan to inhibit the production of both glucagon and insulin, slows GI motility, allowing more time for food to be absorbed.

Pancreatic Histology: Exocrine Tissue Pancreatic Histology: Exocrine Tissue. The pancreas is surrounded by a very thin connective tissue capsule that invaginates into the gland to form septae, which serve as scaffolding for large blood vessels. Further, these septae divide the pancreas into distinctive lobules, as can clearly be seen in the image of mouse pancreas below (H&E). The large spaces between lobules seen in this image are a commonly-observed artifact of fixation.

The Endocrine System: Hypothalamus, Pituitary, & Pineal Glands There are two parts to the pituitary gland: The anterior pituitary and the posterior pituitary. The anterior pituitary stores hormones such as TSH (thyroid stimulating hormon … e), ACTH (adrenocorticotropic hormone), GH (Growth hormone), FSH (follicle-stimulating hormone), LH (lutenizing hormone), and Prolactin.

Adrenal gland Adrenal gland. The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol.[1][2] They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla.

Pancreatic islets The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. Discovered in 1869 by German pathological anatomist Paul Langerhans, the pancreatic islets constitute approximately 1-2% of the pancreas's mass and receive 10-15% of its blood flow.here are about one million islets distributed throughout the pancreas of a healthy adult human, :914 each of which measures about 0.2 mm in diameter.

- Islets of Langerhans. The islets of Langerhans are the endocrine (endo= within) cells of the pancreas that produce and secrete hormones such as insulin and glucagon into the bloodstream. The pancreatic hormones, insulin and glucagon, work together to maintain the proper level of sugar (glucose) in the blood. Blood sugar is used by the body for energy. An understanding of the two functional components of the pancreas is important for two reasons.
