The transverse process of a thoracic vertebra also articulates at the transverse costal facet with the tubercle of the rib of the same number. The crest gives attachment to the intra-articular ligament. [5] The neck of the rib is the flattened part that extends laterally from the head. The neck is about 3 cm long.
The costovertebral joints are the joints that connect the ribs to the vertebral column. The articulation of the head of rib connects the head of the rib and the bodies of vertebrae. The costotransverse joint connects the rib with the transverse processes of vertebrae.
A tubercle of rib on the posterior surface of the neck of the rib, has two facets (surfaces) one articulating and one non-articulating. The articular facet, is small and oval and is the lower and more medial of the two, and connects to the transverse costal facet on the thoracic vertebra of the same rib number. [ 5 ]
The external oblique functions to pull the chest downwards and compress the abdominal cavity, which increases the intra-abdominal pressure as in a Valsalva maneuver.It also performs ipsilateral (same side) side-bending and contralateral (opposite side) rotation: the right external oblique would side-bend to the right and rotate to the left, and vice versa.
The superior costal facet (or superior costal fovea) is a site where a rib forms a joint with the top of a vertebra. Ribs connect to the thoracic vertebrae at two main points, the inferior and superior costal facets. These connection points are located on two different vertebrae that are located on top of one another.
Kyphosis (left) and scoliosis (right) depicting iliocostal contact (a) Symptoms: Pain in the lower rib, flank, groin, thigh, or buttocks. Causes: Contact between the ribs and the iliac crest: Risk factors: Osteoporosis, hyperkyphosis, and scoliosis: Diagnostic method: Physical examination, x-ray, CT scan: Treatment: Orthosis, nerve blocks ...
On a rib, tubercle is an eminence on the back surface, at the junction between the neck and the body of the rib.It consists of an articular and a non-articular area. The lower and more medial articular area is a small oval surface for articulation with the transverse process of the lower of the two vertebrae which gives attachment to the head.
A cutout of the thoracic wall showing the three layers of intercostal muscle - from the left wall. The muscles extend from the tubercles of the ribs behind, to the cartilages of the ribs in front, where they end in thin membranes, the external intercostal membranes, which are continued forward to the sternum.
