Transverse costal facet

The Transverse Costal Facet is a specific anatomical feature found on the thoracic vertebra of the vertebral column. It is a small, smooth, concave surface that provides a point of articulation for the rib.

Anatomy

The transverse costal facet is located on the transverse process of the thoracic vertebra. It is where the tubercle of the rib articulates, forming a synovial joint. This joint allows for the movement and flexibility of the rib cage during respiration.

Function

The primary function of the transverse costal facet is to provide a point of articulation for the ribs. This allows for the movement and expansion of the rib cage during respiration, facilitating the process of breathing.

Clinical Significance

Abnormalities or injuries to the transverse costal facet can lead to conditions such as Costovertebral joint dysfunction, which can cause pain and restricted movement. Treatment may involve physical therapy, medication, or in severe cases, surgery.
