ATLANTAL EXTREMITIES Meaning and
Definition
-
Atlantal extremities refers to the topmost bony structures located in the region of the neck, specifically at the level of the first cervical vertebra, also known as the atlas. The atlas is the vertebra that supports the skull and connects the cranial skeleton to the spinal column. The term "atlantal extremities" encompasses the various anatomical features associated with this region.
These extremities include the condyles, which are rounded surfaces on the uppermost portion of the atlas that articulate with the skull, forming the atlanto-occipital joint. This joint allows for the flexion and extension movements of the head. The Atlantal tubercles are small bumps on the lateral aspects of the atlas that serve as attachment points for ligaments, providing stability to the craniovertebral junction.
The atlantal extremities also include the anterior and posterior arches, which are bony structures that enclose the spinal canal. These arches protect the delicate neural structures within the spinal cord. Additionally, the transverse processes of the atlas are considered part of the atlantal extremities. These are bony projections that extend laterally from the atlas and serve as attachment sites for muscles and ligaments involved in head and neck movements.
In summary, the term "atlantal extremities" encompasses the various structures and features of the topmost vertebra, the atlas, including the condyles, tubercles, arches, and transverse processes. These structures contribute to the stability, flexibility, and protection of the craniovertebral junction and facilitate movements of the head and neck.
