Atlantoaxial joint
Describe the atlantoaxial joint
Are synovial joints, consisting of two lateral plane joints, which are between articular facets of the atlas and axis, and one median pivot joint
between the dens of the axis and the anterior arch of the atlas.
Atlantoaxial joint has
Cruciform ligament Transverse ligament Longitudinal ligament Apical ligament Alar ligament Tectorial membrane
Ligamentum flavum
Connects the lamina of two adjacent vertebrae
Forms the posterior wall of the vertebral canal between
Ligamentum nuchae
(back of neck)
extend from
vertebra C7 to the external occipital protuberance and crest.
Anterior longitudinal ligament
on the anterior surface of the vertebral bodies and intervertebral disks.
Posterior longitudinal ligament
Supports the posterior aspect of the vertebral bodies and the anulus fibrosus, but it runs anterior to the spinal cord within the vertebral canal.
Acromioclavicular joint
Is a synovial plane joint that allows a gliding movement
Shoulder (glenohumeral) joint
Is surrounded by the fibrous capsule
The capsule is reinforced by the rotator cuff, the glenohumeral ligaments,
and the coracohumeral ligaments.
Bursae around the shoulder
Form a lubricating mechanism between the rotator cuff and the coracoacromial arch during movement of the shoulder joint.
- Subacromial bursa
- Subdeltoid bursa
- Subscapular bursa
Annular ligament is found
Elbow joint
forms nearly four-fifths of a circle around the
head of the radius; the radial notch forms the remainder.
