TUBERCULUM SELLAE Meaning and
Definition
-
Tuberculum sellae, also known as the sellar tubercle, is a specific anatomical feature located on the sella turcica, which is a small bony depression in the sphenoid bone of the skull. This term is primarily used in the field of medical and anatomical science.
The tuberculum sellae is a prominent bony ridge that forms the anterior border of the sella turcica. It is situated in the middle of the sphenoid bone, at the base of the brain, and specifically at the junction of the anterior and posterior clinoid processes. The sella turcica and its associated structures are crucial in housing and protecting the pituitary gland.
The tuberculum sellae serves as an anatomical landmark for various surgical and radiological procedures. It provides a reference point for surgeons during transsphenoidal approaches to the pituitary gland, as well as in other sellar region surgeries. Additionally, radiologists use this structure to assess and analyze findings from radiographic imaging of the skull and pituitary region.
Overall, the tuberculum sellae is an important anatomical structure that aids in localizing and identifying specific areas within the sellar region of the skull. Its prominence and distinct location make it a useful reference point for medical professionals involved in various diagnostic, surgical, and radiological procedures in this area of the head.
Etymology of TUBERCULUM SELLAE
The word "tuberculum sellae" has its etymology rooted in Latin. Here's a breakdown of the terms:
1. Tuberculum: The word "tuberculum" comes from the Latin word "tuber" which means "a swelling" or "a lump". In anatomy, it refers to a small, rounded projection or bump on a bone.
2. Sellae: The term "sellae" is the genitive form of the Latin word "sella" which means "saddle". In anatomy, it refers to the saddle-shaped depression on the upper surface of the sphenoid bone, known as the "sella turcica".
When combined, "tuberculum sellae" refers to the small rounded projection or bump located on the upper surface of the sella turcica, specifically on the sphenoid bone.
