Forms the posterior hind margin of the cranium and borders the lateral and posterior margins of the forum (foramen) magnum.

UBPROP 0000001

Endochondral bone that forms the posterior end of the neurocranium and the margin of the foramen magnum. In addition, this bone forms either part of or all or the occipital condyle.[AAO], Endochondral bone that articulates with the epiotic dorsally, the pterotic and intercalar laterally and the basioccipital medio-ventrally. The exoccipitals form the lateral borders of the foramen magnum and houses the foramina for the passage of the vagus and glossopharyngeal nerves, X and IX respectively. The exoccipital is a paired bone.[TAO]
