Answer :
The five regions of the vertebral column are cervical, thoracic, lumbar, sacral, and coccygeal (or caudal) regions.
The vertebral column is the central axis of all vertebrates. It protects the spinal cord, provides attachment to the muscle cells, and supports the trunk. It usually consists of 33 vertebrae. The vertebral column in mammals is composed of five different groups of vertebrae:
Cervical region
The primary function is to support the weight of the head. They are numbered C1 to C7. C1 and C2 allow movement of the head.
Thoracic region
The primary function is to hold the rib cage in its place and protect the heart and lungs. They are numbered T1 to T12. They allow limited movement only.
Lumbar region
The primary function is to hold the weight of the body. They have numbered L1 to L5. They allow holding heaving weight.
Sacral region
The main function is to connect the spine to the hip bones (iliac). The five sacral bones are fused and form the pelvic girdle along with the iliac bones.
Coccygeal region
The four coccyx bones provide support to the attachment of ligaments and muscles of the pelvic region.
With the support of the above answer, we can say that there are five regions in a vertebral column, namely, cervical, thoracic, lumbar, sacral, and coccygeal.
