The pancreas is both an exocrine and endocrine gland. Its endocrine hormone secretions include insulin and glucagon. Its exocrine secretions consist mainly of digestive enzymes such as amylase, lipase, trypsin and chymotrypsin.

Endocrine gland larger in children than adults?
The thymus, which hides behind the sternum. It shrinks as you get older and is only active in children.
Why the release of acetylcholine at the neuromuscular junction is not considered a hormonal event?
Because it is released by a motor neuron and not an endocrine gland. Hormones are released only by glands.
Which glands lose their connection with epithelium during embryonic development and secrete their cellular products only into the bloodstream?
These glands are called endocrine glands. The other glands place its' product on a surface and are called exocrine glands.
Is hypothalamus a part of brain or gland?
The hypothalamus is part of an organ - that being the brain. It isn't a gland, because it only secretes hormones locally. The pituitary is a gland because it secretes hormones into the bloodstream for distant effects.
What is another name of the glands in your neck?
In your neck there are really only 2 different types endocrine glands: the thyroid gland and the parathyroid glands. You may be speaking of the parathyroid glands, which are 4 little glands that lie on the back of the thyroid.
Is both an endocrine and an exocrine gland?
No. Adrenal gland has got only endocrine function. It does not have exocrine functions.
What are the main organs and functions for the endocrine system?
The main organs/glands are the pancreas, thyroid, thymus, adrenal glands, pituitary gland, ovaries, and testes. The function of the Endocrine system is to produce hormones that affect growth, sexual development, and your fight-or-flight reaction. The pancreas is unique in that it's the only organ with both endocrine and exocrine glands. :)
What is the difference between endocrine and exocrine glands?
Endocrine glands secrete their hormones directly into the bloodstream. Exocrine glands secrete their hormones into a duct that leaves the body externally: for example, sweat glands empty onto the skin. Endocrine gland secretes compounds (hormones) into the blood. Exocrine gland secretes compounds outside of the body (including into the GI tract since the GI tract is topologically outside of the body). Exocrine glands have ducts that carry their secretory product to a surface. These glands include the sweat, sebaceous, and mammary glands and, the glands that secrete digestive enzymes.The endocrine glands do not have ducts to carry their product to a surface. They are called ductless glands. The word endocrine is derived from the Greek terms "endo," meaning within, and "krine," meaning to separate or secrete. The secretory products of endocrine glands are called hormones and are secreted directly into the blood and then carried throughout the body where they influence only those cells that have receptor sites for that hormone.
What endocrine gland if found in males only?
Prostate
Which endocrine organs are actually mixed endocrine and exocrine glands Which are purely endocrine?
The endocrine system controls the functions of the organs throughout the body. Mixed endocrine and exocrine glands are the pancreas, ovaries and testes they produce hormones but are also involved in other roles. Pure endocrine glands are the thyroid, parathyroid, adrenal cortex, thymus and pineal their only function is to create hormones.
Is insulin secreted by endocrine or exocrine glands?
Insulin is synthesized in significant quantities only in beta cells in the pancreas.
How do endocrine glands differ from other glands?
Endocrine glands secrete hormones and exocrine glands secrete enzymes. Endocrine glands secrete hormones directly into the blood stream, while exocrine glands secrete enzymes through ducts. endocrine is ductless gland exocrine retain their duct, exocrine empty through their duct to epithelial such as sweat, oil, glands, liver and pancrease
Why isn't the neurohypophysis or posterior lobe of the pituitary gland a true endocrine gland?
It is only a hormone storage area that receives hormones from the hypothalamus for release. Since it does not make its own secretions (it only stores the neuroendocrine hormones made by the hypothalamus) it is not considered a true endocrine gland.
Is the posterior pituitary gland a true endocrine gland?
It is only a hormone storage area that receives hormones from the hypothalamus for release.
How do the endocrine and exocrine gland's differ in structure and function?
The glands in human body are of two types. One is exocrine glands and the other isendocrine glands. The exocrine glands produce fluid secretions that are delivered by tubes or ducts either to the body surface for example glands of skin or to the inner regions where these are required for example pancreas delivers its pancreatic juice to the intestine for digesting food etc. Endocrine glands produce secretions called hormones that are not carried by ducts but are passed into the blood streamand carried to the target area by blood circulation. The following endocrine glands are present in human body; pituitary gland, pancreas (islets of langerhans), thyroid gland, adrenal glands, and gonads. The function of endocrine glands is very much inter-related. Several of the hormones produced by them serve only to alter the functions of other endocrine glands. They serve as double check automatic control over one another. The pituitary gland is known as master gland in the body and plays an important role in several ways. It has certain hormones which have direct action on the body for example the growth hormone. Thyroid gland is located in the neck and fits closely around the from and side of trachea just below the organ of voice of larynx.Endocrine glands lose their connection to the surface, and are often called ductless glands. Their secretions diffuse directly into the blood vessels that weave through the glands. Exocrine glands retain their ducts and their secretions empty through the ducts to the epithelieal surface. They are both internal and external.The function of the endocrine system is to secrete regulatory hormones into the bloodstream, whereas the exocrine system is designed to secrete substances other than hormones, into ducts which lead to the external environment. To compare structure, endocrine glands are far more vascular, and do not require ducts. Endocrine glands include such organs as the pituitary and adrenal glands. Exocrine glands include such things as sweat, salivary and mammary glands.Not all glands are exclusively endocrine or exocrine; the pancreas produces both insulin which is released into the bloodstream, and pancreatic juices which are directed into the digestive tract via the pancreatic duct.Endocrine Glands eventually lose their ducts, they are often call doctles glands; they produce hormones.Exocrine Glands secrete their products into body surfaces (skin) or body cavities, they include mucous, sweat, osl, and salivary glands.Unicellular exocrine glands produ mucin a glyro protain that dissolve in water when secreted, once disolve musin forms mucus.

Is a chemical substance produced by an endocrine gland known as a hormone or not?
Of course they are hormones. Hormones are only produced by endocrine glands
