Detailed explanation-1: -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.
Detailed explanation-2: -The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone).
Detailed explanation-3: -The brainstem connects the brain and the spinal cord. It is made up of the pons, the medulla (meh-DULL-uh), and the midbrain. These parts work together to control and coordinate the messages going in and out of the brain.
