Inferior hypophysial artery

Inferior hypophysial artery is a small artery that supplies blood to the pituitary gland. The term "inferior hypophysial artery" is derived from the Latin words "inferior" meaning lower, and "hypophysis" referring to the pituitary gland.

Anatomy

The inferior hypophysial artery originates from the meningeal branch of the internal carotid artery. It travels downwards to reach the sella turcica, where it branches off to supply the posterior lobe of the pituitary gland.

Function

The primary function of the inferior hypophysial artery is to supply blood to the posterior lobe of the pituitary gland. This is crucial for the gland's function, as it ensures the delivery of necessary nutrients and oxygen, and the removal of waste products.

Clinical significance

Damage to the inferior hypophysial artery can lead to hypopituitarism, a condition characterized by decreased secretion of hormones from the pituitary gland. This can result in a variety of symptoms, including fatigue, weakness, decreased appetite, weight loss, and sexual dysfunction.
