Here, the occipital condyle is a single rounded projection that is present on the rear of the skull and articulates with the first cervical (neck) vertebra. The occipital bone, like the other seven cranial bones, has outer and inner layers (also called plates or tables) of cortical bone tissue between which is the cancellous bone tissue known in the cranial bones as diplo.The bone is especially thick at the ridges, protuberances, condyles, and anterior part of the basilar part; in the inferior cerebellar fossae it is thin . Occipital condyle syndrome consists of unilateral pain in the occipital region with ipsilateral hypoglossal neuropathy manifesting as tongue weakness, atrophy, and fasciculations (Laigle-Donadey et al., 2005). The occipital bone is an anteriorly concave bone that forms the base of the cranium.

The morphological features of occipital condyles are relevant in biomechanical, anatomical and clinical studies. The hypoglossal canal is . The occipital condyles "lay on", or articulate with, the lateral masses of the first cervical vertebra, also known as atlas. The vertebra has a pair of lateral masses protruding laterally, the anterior arch connecting the two lateral masses, and the three articular surfaces; two for occipital condyles, facing superiorly and one for the dens of C 2.

The occipital bone ( L., occipital - "back of the head") is a cranial bone that surrounds the back and base regions of the brain. The occipital bone houses the back part of the brain and is one of seven bones that come together to form the skull. No rotation occurs at the atlanto-occipital joint. All modern reptiles have the diapsid skull type, except for turtles which have anapsid skulls. b. External occipital protuberance: Definition. occipital condyles: articulate with the atlas (C1), permitting flexion and extension (nodding) with minimal lateral flexion. The occipital bone is the trapezoid-shaped bone at the lower-back of the cranium (skull).
