DORSUM SELLAE Meaning and Definition

1. Dorsum sellae is a Latin phrase used in anatomy to refer to a specific anatomical feature found in the cranial region of the human skull. The term is derived from the Latin words "dorsum" which means "back" and "sellae" which means "saddle". It is commonly defined as the bony ridge or crest that forms the posterior aspect of the sella turcica.

   The sella turcica is a saddle-shaped depression located in the sphenoid bone of the skull. It is situated in the middle cranial fossa, a depression on the base of the skull. The dorsum sellae represents the back portion of this saddle-shaped structure, forming a bony ridge that extends posteriorly and separates the sella turcica from the posterior cranial fossa.

   The dorsum sellae serves as an important landmark in cranial anatomy and is involved in various anatomical and surgical considerations. It provides attachment points for several ligaments and membranes that surround and support the pituitary gland, a crucial endocrine organ located within the sella turcica. Additionally, the presence of the dorsum sellae can affect the approach and techniques used in certain surgical procedures involving the sella turcica and the surrounding structures.

   In conclusion, dorsum sellae refers to the posterior bony ridge of the sella turcica, an anatomical structure in the cranial region of the skull. It plays a significant role in providing attachment points and aiding in surgical procedures related to the pituitary gland and adjacent areas.

2. A square portion of bone on the body of the sphenoid posterior to the sella turcica, or fossa hypophyseos.
