occipital bone
The occipital condyles are oval-shaped structures on the occipital bone that articulate with the superior facets of the atlas (C1 vertebrae). This joint, called the atlanto-occipital joint, allows for flexion and extension of the head.
Occipital condyles
The Hyoid bone does not have any articulations. It is commonly described as a gyroscope. It is held in place by the suprahyoid and infrahyoid musculature. It has a deep relationship with the Atlas however does not articulate directly with it.
The cervical and lumbar vertebrae do not articulate with the ribs. The thoracic vertebrae are the only ones that articulate with the ribs.
The occipital condyle articulates with the first cervical vertebra (atlas) to form the atlanto-occipital joint. This joint allows for nodding movements of the head.
The occipital condyles "lay on", or articulate with, the lateral masses of the first cervical vertebra, also known as atlas.
The atlas articulates with the axis. The atlas is the first cervical vertebra and articulates with the skull superiorly, and the axis (the second cervical vertebra) inferiorly. The joint between the atlas and axis, dubbed the atlanto-axial joint, is responsible for the increased range of motion of the skull (turning your head left/right, and nodding up/down).The order of the atlas and axis can be remembered because, beginning from the skull, these two cervical vertebrae are in alphabetical order (aTlas then aXis).
The axis, or second cervical vertebra (C2), articulates with two bones: the atlas (C1), which is the first cervical vertebra, and the occipital bone of the skull. The joint between the atlas and axis allows for the rotation of the head, while the connection with the occipital bone facilitates nodding movements.
