Vertebral Column MCQs

The tubercle of a rib is a projection located posteroinferior and lateral to the neck of the rib. It articulates with the transverse process of the vertebra of the same number. So, the tubercle of rib 7 should articulate with the transverse process of the T7 vertebra. The head of the rib is the part of the rib that articulates with the demifacets of two adjacent vertebral bodies. So, the head of rib 7 should articulate with the 6th vertebra superiorly and the 7th vertebra inferiorly. Reference- Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 127

The tip of the 13 spinous process corresponds to the root of the spine of the scapula Other important surface markings of scapula: Superior angle of scapula: at the level of 2nd rib and vertebra T2. Inferior angle of scapula: opposite the 17 vertebral spinous process. Reference : Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 126

1st rib is an atypical rib and does not articulate at 3 sites with a vertebra. It has 2 articulations as follows: Circular facet on the head of the rib with the body of the first thoracic vertebra Tubercle of the rib to the transverse process of the corresponding vertebra Reference : Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 124

Kyphosis is an abnormal increase in the thoracic curvature of the vertebral column. An abnormal increase in lumbar curvature due to anterior sway of the pelvis is called lordosis. (Women develop temporary lordosis during pregnancy to compensate for the change in their normal line of gravity.) Finally, scoliosis is an abnormal lateral curvature of the spine accompanied by a rotation of vertebrae. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Back, Page number - 104

Carotid Pulsation: The pulsation of common carotid artery can be felt by compressing against the carotid tubercle, i.e. the anterior tubercle of the transverse process of vertebra C6 which lies at the level of the cricoid cartilage.

Answer- B. Spondylolisthesis Displacement (partial) of one vertebrae over other is called Spondylolisthesis. Spondylolisthesis is a defect in the pars interarticularis.

Answer- C. Aortic aneurysm Posterior scalloping is the concavity to the posterior aspect of the vertebral body. Anterior Scalloping is the concavity to the anterior aspect of the vertebral body.

The spinous processes of vertebrae do not provide articulation to ribs. Note: Two facets on head of the ribs are separated by a transverse crest which is attached to the intervertebral disc above it. Reference : Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 124
