Vertebrae(T1-T12)(L1-L5)(Sacrum)(Coccyx)(Axial Skeletal) ( Lab Practical)

Question 1

T1-T12

Answer 1

• Transverse costal facets: smooth articulating surfaces on the transverse processes for articulation with the tubercle of a rib
• Costal facets: small indentations on the lateral aspect of the vertebral bodies for articulation with the head of a rib. Most thoracic vertebrae have two costal facets, one superior and one inferior costal facet.

Question 2

L1-L5

Question 3

Sacrum

Answer 3

• Superior articular process: Articulates with the L5 at superior articular processes and inferiorly with the coccyx
• Sacral foramina: openings for sacral nerves
• Median sacral crest: on the posterior side, a remnant of the spinous processes of the fused vertebrae
• Sacral canal: the continuation of the vertebral foramen through the sacrum

Question 4

Coccyx
