How does the skull articulate with the vertebral column?

How 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.

What is the articular surface between the skull and vertebrae?

The atlas is the topmost vertebra and, with the axis (the vertebra below it), forms the joint connecting the skull and spine. The atlas and axis are specialized to allow a greater range of motion than normal vertebrae. They are responsible for the nodding and rotation movements of the head.

What type of articulation is present between the vertebral bodies?

intervertebral cartilaginous joint
Articulations. intervertebral cartilaginous joint: the inferior and superior surfaces of the vertebral bodies are covered by a layer of hyaline cartilage. The fibrocartilaginous intervertebral disc then adheres to these layers of cartilage between the adjacent vertebral bodies.

What are the two types of articulation found in the vertebral column?

There are two sets of craniovertebral joints: the atlanto-occipital joints and the atlanto-axial joints, both of which are synovial joints that allow for a much wider range of motion than the rest of the joints of the vertebral column.

Which vertebrae articulates with the skull?

atlas: the first cervical vertebra (C1), lying directly under the skull, through which the head articulates with the neck.

What are the differences between a Vertebrosternal Vertebrochondral and vertebral rib?

What is the main difference between vertebrosternal and vertebrochondral ribs? a. Vertebrosternal ribs attach to the sternum by their own costal cartilages. Vertebrochondral ribs’ costal cartilages fuse and merge with cartilages from rib 7.

What type of joint is between the skull and vertebral column?

craniovertebral joint
A craniovertebral joint is exactly what it sounds like: a joint that permits movement between the vertebral column and the skull. The ligaments in the spine support and reinforce the joints between the vertebrae. The atlas and axis in particular work with the ligaments to move the neck.

What articulates 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. Below these are the 12 thoracic vertebrae, designated T1–T12. The lower back contains the L1–L5 lumbar vertebrae.

What is the difference between the way the ribs articulate with the sternum and vertebrae?

On an individual rib, one end has various processes, facets, and bumps. This is the end that articulates with the vertebra. Ribs 8, 9, and 10 do connect to costal cartilage, but the costal cartilage of each of these ribs connects to the costal cartilage of the rib above it, rather than directly to the sternum.

What are the articulations of the vertebral column?

Human Body > III. 5c. Articulations of the Vertebral Column with the Cranium. The ligaments connecting the vertebral column with the cranium may be divided into two sets: those uniting the atlas with the occipital bone, and those connecting the axis with the occipital bone.

How is the vertebral column connected to the cranium?

Articulations of the Vertebral Column with the Cranium The ligaments connecting the vertebral column with the cranium may be divided into two sets: those uniting the atlas with the occipital bone, and those connecting the axis with the occipital bone. Articulation of the Atlas with the Occipital Bone (articulatio atlantoöccipitalis).

What is the articulation between the Atlas and the occipital bone?

—The articulation between the atlas and the occipital bone consists of a pair of condyloid joints. The ligaments connecting the bones are: Two Articular Capsules. The Posterior Atlantoöccipital membrane. The Anterior Atlantoöccipital membrane. Two Lateral Atlantoöccipital. The Articular Capsules (capsulœ articulares; capsular ligaments).

How many vertebrae are in the adult vertebral column?

Figure 7.4.1 – Vertebral Column: The adult vertebral column consists of 24 vertebrae, plus the fused vertebrae of the sacrum and coccyx. The vertebrae are divided into three regions: cervical C1–C7 vertebrae, thoracic T1–T12 vertebrae, and lumbar L1–L5 vertebrae.
