APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The atlas and axis form the atlanto-axial joint, which allows head rotation. If you shake your head as if to say “no, ‘’ that is head rotation. The atlanto-axial joint is a compound synovial joint.

Detailed explanation-2: -The multipurpose function of the atlantoaxial joint is crucial in practical application, allowing the head to rotate and turn to the left or right.

Detailed explanation-3: -Hinge joints. Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements. Pivot joints. Pivot joints, such as the neck joints, allow limited rotating movements.

Detailed explanation-4: -Being a ball-and-socket joint, the hip joint permits movements in three degrees of freedom: flexion, extension, abduction, adduction, external rotation, internal rotation and circumduction.

Detailed explanation-5: -There are only two areas on the skull where synovial joints are present. The first is a pair of joints; the temporomandibular joints, where the mandible articulates with the skull on either side. The second synovial joint is the atlanto-occipital joint, where the base of the skull articulates with the vertebral column.
