Pars intermedia
Pars intermedia
Pars intermedia (pronunciation: /pɑːrs ɪntərˈmiːdiə/) is a part of the pituitary gland, specifically the anterior pituitary, also known as the adenohypophysis.
Etymology
The term "pars intermedia" is derived from Latin, where "pars" means part and "intermedia" means intermediate. This term is used to describe its location, which is intermediate between the anterior pituitary and the posterior pituitary.
Function
The pars intermedia produces and secretes melanocyte-stimulating hormone (MSH), which plays a crucial role in the regulation of skin color in many vertebrates. It also has a role in appetite regulation and energy balance.
