Do C1 and C2 have facet joints?

The C1 and C2 vertebrae are connected in the back by a pair of facet joints. The ring-shaped atlas rotates around the dens, which is the peg-like bony projection of the axis.

What movement does C1 and C2 allow?

C1 and C2 Vertebrae Names The second vertebra, C2, is called the axis in reference to its purpose — enabling motion. When together, atlas C1 and axis C2 allow for rotation and swiveling of the head since the C1 vertebrae is attached directly into the skull and pivots from its C2 axis.

What type of joint is found between C1 atlas and C2 axis?

synovial joints
The atlanto-axial joints are formed by the articulation between the atlas and the axis: Lateral atlanto-axial joints (x2) – formed by the articulation between the inferior facets of the lateral masses of C1 and the superior facets of C2. These are plane type synovial joints.

What are the characteristics of C1 and C2?

The C1-C2 vertebrae and spinal segment include the following structures: C1 and C2 vertebrae. The C1 vertebra, also called atlas, is shaped like a ring. The atlantoaxial joint. The joint between the C1 and C2 vertebrae is called the atlantoaxial joint. C2 spinal nerve. The C2 dermatome is an area of skin that receives sensations through the C2 nerve. The C2 myotome is a group of muscles controlled by the C2 nerve.

What is the difference between the C1 and C2 vertebrae?

In Human Anatomy and Physiology. The name of the joint that is between C1 & C2 is the atlantoaxial joint. C1 is the atlas and C2 is the axis. The type of joint is called a pivot joint, and often referred to as the no-no joint, because it is used to rotate your head left and right, as in saying ‘no’.

What is C2 spine?
