The pancreas is an organ of the digestive system and endocrine system of vertebrates.In humans, it is located in the abdomen behind the stomach and functions as a gland.The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function.
The pituitary gland (or hypophysis) is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae).
Beta cells are the only site of insulin synthesis in mammals. [7] As glucose stimulates insulin secretion, it simultaneously increases proinsulin biosynthesis through translational control and enhanced gene transcription.
One part is from the thickening of the pharyngeal floor, which serves as the precursor of the thyroxine (T 4) producing follicular cells. The other part is from the caudal extensions of the fourth pharyngobranchial pouches which results in the parafollicular calcitonin-secreting cells. These two structures are apparent by 16 to 17 days of ...
It is the part of the throat immediately behind the nasal cavity at the back of the mouth and above the esophagus and larynx. The pharynx is made up of three parts. The lower two parts—the oropharynx and the laryngopharynx are involved in the digestive system. The laryngopharynx connects to the esophagus and it serves as a passageway for both ...
Gross anatomy has become a key part of visual arts. Basic concepts of how muscles and bones function and deform with movement is key to drawing, painting or animating a human figure. Many books such as Human Anatomy for Artists: The Elements of Form , are written as a guide to drawing the human body anatomically correctly. [ 4 ]
The most well studied is through the action of extra-pancreatic glucose sensors, including neurons found in the brain, which exert control over the alpha cells in the pancreas. [5] The pancreas is controlled by both the sympathetic nervous system and the parasympathetic nervous system , although the method these two systems use to control the ...
