Where does the skull join with the atlas?
The Atlas: The Top Bone in Your Cervical Spine A pair of synovial joints, known as the atlanto-occipital joint connect the atlas and your skull.
Does the atlas articulate with the skull?
atlas: the first cervical vertebra (C1), lying directly under the skull, through which the head articulates with the neck. The main connection to the vertebra below is a pivot around the odontoid process that is an upward projection of the body of the second cervical vertebra.
Is the atlas fused to the skull?
The skull has a complete fusion of the anterior and posterior arches and transverse processes of atlas with the adjoining part of occipital bone. Articular process of atlas and corresponding occipital condyle on both the sides are completely fused.
Where does the skull articulate with the vertebral column?
Superiorly, the C1 vertebra articulates (forms a joint) with the occipital condyles of the skull. Inferiorly, C1 articulates with the C2 vertebra, and so on.
Where is C1 in the spine?
cervical spine
The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Together they form the atlantoaxial joint, which is a pivot joint. The C1 sits atop and rotates around C2 below.
What is at the base of your skull?
At the base of the skull is bone that supports 4 brain components—the frontal lobe, temporal lobe, brain stem, and cerebellum. The skull base offers support from the bottom of the brain. Think of it as the floor of the skull, where the brain sits.
Where is the vertebral body of the atlas?
neck
Anatomical terms of bone In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck. It is named for Atlas of Greek mythology because, just as Atlas supported the globe, it supports the entire head.
Is the spine connected to the skull?
The cervical spine has 7 stacked bones called vertebrae, labeled C1 through C7. The top of the cervical spine connects to the skull, and the bottom connects to the upper back at about shoulder level.
How is the skull attached to the body?
The neurocranium is a protective shell surrounding the brain and brain stem. The viscerocranium (or facial skeleton) is formed by the bones supporting the face. Except for the mandible, all skull bones are joined together by sutures —synarthrodial (immovable) joints.
What articulates with the vertebral column?
The highest cervical vertebra articulates with the skull; the thoracic vertebrae articulate with the ribs; and the sacrum articulates with the two innominate bones to form the pelvis. When seen from in front, the spine appears straight, but when we look at it from the side, we see that it’s markedly curved.
Which vertebrae do the ribs articulate with?
The ribs articulate posteriorly with the T1–T12 thoracic vertebrae, and most attach anteriorly via their costal cartilages to the sternum. There are 12 pairs of ribs.
