 Identification :-

                   Cervical spine

• The cervical spine, comprised of seven cervical vertebrae referred to as C1 to C7, is divided into two major segments: the craniocervical junction (CCJ) and the subaxial spine.

• Small size, transverse foramina, saddle-shaped body, and bifid spinous process.

                    Thoracic spine

• Thoracic spine consists of 12 vertebrae, labeled T1 through T12.

• It’s the longest section of your spine.

• It starts at the base of your neck and ends at the bottom of your ribs.

                    Lumbar spine

• Lumbar spine is located below your 12 chest (thoracic) vertebra and above the five fused bones that make up your triangular-shaped sacrum bone.

• Lumbar vertebrae, known as L1 to L5

• Lumbar vertebrae are the largest of your entire spine.

                           Sacrum

• The sacrum forms the posterior pelvic wall and strengthens and stabilizes the pelvis.

• connected to the pelvis

• located at the base of the lumbar vertebrae.

• The sacrum is formed by fusion of the 5 sacral vertebrae.

                          Coccyx

• The coccyx consists of 4-5 fused rudimentary vertebrae.
