MEDICAL PHYSIOLOGY

Detailed explanation-1: -The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae. Five vertebrae are fused together to form the sacrum (part of the pelvis), and four small vertebrae are fused together to form the coccyx (tailbone).

Detailed explanation-2: -The vertebrae (back bones) of the spine include the cervical spine (C1-C7), thoracic spine (T1-T12), lumbar spine (L1-L5), sacral spine (S1-S5), and the tailbone. Each vertebra is separated by a disc. The vertebrae surround and protect the spinal cord.

Detailed explanation-3: -Your spinal cord is a cylindrical structure that runs through the center of your spine, from your brainstem to your low back. It’s a delicate structure that contains nerve bundles and cells that carry messages from your brain to the rest of your body. Your spinal cord is one of the main parts of your nervous system.

Detailed explanation-4: -The spinal cord is a part of the central nervous system. It is a long pipe-like structure arising from the medulla oblongata, part of the brain consisting of a collection of nerve fibres, running through the vertebral column of the backbone.

Detailed explanation-5: -An essential feature of the central nervous system (CNS), the spinal cord lies within the spinal column and extends from the brainstem to the lower back through the vertebral foramen of the vertebrae. In adults, the spinal cord terminates in the lumbar region at L1-L2, the conus medullaris.
