What is intermediate pars?

Intermedia pars is part of the pituitary gland in the brains of vertebrates. The hormone stimulating melanocytes (MSH), which is produced in this area, determines the pigmentation of the skin in human fruits. MSH also affects the ability of fish and amphibians to darken their color for camouflage. PARS intermediate disorders cause common disease in horses called pituitary gland (ppid).

During the development of vertebrate embryo, depression is formed in the roof of the mouth. This depression, called Rathke's pouch, is separated from the roof at a later stage of development. The front of the bag then forms the front of the pituitary and the rear part forms the intermediate pars. In humans, intermediate pars decreases with age and can be completely missing in adults.

pars intermedia forms the boundary between the front and back of the pituitary. Its primary function of the production and excretion of MSH, but other hormones are also present. Adrenocorticotropic hormone (ACTH) concerns growth and nutrition. Another hormone of the region is corticotropin -like intermediatePeptide (Clip) and its important is to act as a precursor ACTH.

MSH affects melanocyte skin cells that contain melanin. The reaction of the hormone and pigment of the skin can produce freckles and moths in human fruits. In fish and amphibians, MSH can branch from the center of melanocyte cells and create a darker skin tone. This is done as a protective camouflage when the creation intersects a darker background.

Ppid, also called Cushing's disease of horses, occurs when the intermediate PARS increases and creates an excessive amount of hormones in the horse's body. This swelling can push the surrounding areas of the pituitary and prevent their function. Horses who are most likely to get PPID for more than 15 years. Symptoms include excessive thirst and development of curly coat that does not penetrate. Treatment usually involves medicines and changes in the diet, as the condition can also cause insulin resistance in the horse.

In humans may incorrect DegrAdation Rathke's Bum cause cyst pars intermedia cyst. These cysts filled with colloids are common, especially in children who are better defined, but often do not cause any symptoms because they have small sizes. Symptomatic cysts can cause headaches and growth disorders that can mimic thyroid problems.
