Sagittal Crest

Bony, ridge-like feature, more prominent than a sagittal ridge, that runs anteroposteriorly on the top of the cranium at the attachment of the temporalis muscles and that is caused by the stresses exerted by the action of those muscles. Present in many primates, including the hominid Paranthropus.

See neurocranium.

Cf. sagittal ridge.
