What type of joint is costovertebral joint?
synovial plane joints
The costovertebral joints describe two groups of synovial plane joints which connect the proximal end of the ribs with their corresponding thoracic vertebrae, enclosing the thoracic cage from the posterior side. Head – Two convex facets from the head attach to two adjacent vertebrae.
Which ribs create the costovertebral joint?
Costovertebral joints, seen from front, intra-articular ligament labeled at lower left. The costovertebral joints are the joints that connect the ribs to the vertebral column. The articulation of the head of the rib connects the head of the rib to the bodies of the thoracic vertebrae.
What are the costovertebral ligaments?
The costovertebral ligaments make the actions of the costovertebral joints and intervertebral movement possible. These ligaments function to affix, stabilize and allow some motion of the ribs on the thoracic vertebra at the costovertebral joint.
Where is the costotransverse ligament?
neck
The superior costotransverse ligament (anterior costotransverse ligament) is attached below to the sharp crest on the upper border of the neck of the rib, and passes obliquely upward and lateralward to the lower border of the transverse process immediately above.
How are the costovertebral and costotransverse joints different?
The costovertebral joint in the thoracic spine is the juncture at which the head of a rib articulates with the vertebral body of a thoracic vertebra. The costotransverse joint is the juncture at which the neck and tubercle of a given rib are united with the transverse process of its corresponding thoracic vertebra.
Where is the Costovertebral Junction?
The rib joints that connect each rib to the second through the tenth vertebrae in the upper back are called costotransverse and costovertebral joints. These joints provide stability to the upper back and chest wall.
What is the articulation of the costovertebral joint?
The costovertebral joint is the articulation between the costal facte or demi-facets (formed by the caudal side of the superior vertebra and the cranial side of the inferior vertebra) and the head of the rib These facets form a solid angle whose base consists of the annulus fibrosis of the intervertebral disc.
How are the costocorporeal and costotransverse joints related?
The movements of the costocorporeal and costotransverse joints are closely related and usually described together. As the joints are firmly stabilized by their respective ligaments, the range of motion is small and falls down to slight gliding and rotational movements of the vertebral ends of the ribs.
Where are the capsules located in the costotransverse joint?
Costotransverse joints are enclosed with their respective fibrous capsules that attach to the margins of the articular facets. The inner surface of each capsule is lined with a synovial membrane which bounds the synovial cavity in each joint.
Are there two types of costovertebral ligaments?
Costovertebral Joint. Each facet is a separate synovial joint. The first rib articulates with the T1 vertebra only and the lowest three ribs articulate only with their own vertebral body 1. There are two types of ligaments:
