What is the shape of the occipital condyles?
What is the shape of the occipital condyles?
The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the posterior extremities extend back to the level of the middle of the foramen magnum.
What is the largest opening in the occipital bone?
the foramen magnum
The most striking feature of the occipital bone is this large opening, the foramen magnum, through which the spinal cord and its accompanying structures pass. The part of the occipital bone in front of the foramen magnum is called the basilar part, often referred to as the base of the occiput.

Where is the occipital condyle?
The occipital condyles are paired kidney-shaped structures that form the base of the occipital bone and are the structural bases for the articulation of the skull with the cervical spine.
What is a occipital condyle?
Definition of occipital condyle : an articular surface on the occipital bone by which the skull articulates with the atlas.
What do the occipital condyles articulate with?
Context: The occipital condyles of the skull articulate with the superior articular facets of the atlas vertebra and form an important junction between the cranium and the vertebral column.
What is the function of occipital condyle?
noun Anatomy. a protrusion on the occipital bone of the skull that forms a joint with the first cervical vertebra, enabling the head to move relative to the neck.
What is medial to the occipital condyle?
Anatomical Parts To their margins are attached the capsules of the atlantooccipital articulations, and on the medial side of each is a rough impression or tubercle for the alar ligament. At the base of either condyle the bone is tunnelled by a short canal, the hypoglossal canal.
What is occipital condyle in anatomy?
The occipital condyles are two large protuberances on the undersurface of the occipital bone, located besides the front half of the foramen magnum. It forms the connection between the skull and the vertebral coloumn.
What does the occipital condyle articulate with?
the atlas vertebra
Context: The occipital condyles of the skull articulate with the superior articular facets of the atlas vertebra and form an important junction between the cranium and the vertebral column.
How many occipital condyles does a lamprey have?
FIGURE 3.2. Chondrocranium of the shark in (a) dorsal view, (b) ventral view, and (c) left lateral view. Posterior to the capsules lies the optic region of the chondrocranium. An orbit, the space occupied in life by the eyeball, lies on either side of this region.
