Diaphragm of the sella turcica

The diaphragm of the sella turcica (lat. Diaphragma sellæ) is a plate of the dura mater, attached to the anterior inclined processes and to the apex of the back of the sella turcica, turning its fossa into the cavity in which the pituitary gland is located. The diaphragm has an opening for the pituitary infundibulum, through which pass the vessels and nerves going to the pituitary gland.

The sella turcica is a part of the main bone of the skull, located in its central part between the eye sockets. On top of the sella turcica there is a fossa in which the pituitary gland is located. The diaphragm sella turcica separates this fossa from the rest of the cranial cavity, forming a pocket for the pituitary gland and protecting it. It plays an important role in the normal functioning of the endocrine system.

The sella diaphragm is an important anatomical structure that plays a key role in regulating the function of the pituitary gland and other brain structures. Discovered in ancient times, it has become the object of study by many scientists, but today its properties and functions remain the subject of debate. In this article we will review basic information about the anatomy and functions of the diaphragm sella and its importance for the normal functioning of the central nervous system.
