Bring Anatomy to life
The External occipital crest is a variable structure positioned between the external occipital protuberance and the posterior border of the foramen magnum. (7,8)
The external occipital protuberance is positioned at the midpoint of the squamous part; it aligns along the midline of the external part of the occipital bone. (1,6)
The squamous part of occipital bone is the part that occupies the most posterior position. It is the largest portion of the bone, located behind the foramen magnum. (1,7)
The condylar fossa is a hollow space found behind each occipital condyle. (3,8)
The Hypoglossal canal is a tunnel originating just above the foramen magnum. It ends anterolaterally to the condyle. (3,7)
