The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain. The brain and spinal cord together make up the central nervous system. Enclosed within, and protected by, the bony vertebral column, the spinal cord functions primarily in the transmission of neural signals between the brain and the rest of the body, but also contains neural circuits that can independently control numerous reflexes and central pattern generators.

Unformatted text preview: • The spinal cord can be subdivided into four regions based on the four regions of the spine, cervical, thoracic, lumbar and sacrocaudal. • • Cord and Roots • Above each vertebra the spinal cord gives off ventral and dorsal rootlets. The ventral rootlets govern motor function while the dorsal rootlets govern sensory information. The ventral (motor) and dorsal (sensory) roots combine to form spinal nerves (mixed; motor and sensory), one on each side of the spinal cord. Spinal nerves, with the exception of C1 and C2 form inside intervertebral foramen (IVF). • • The Meninges • The meninges (singular meninx) are the system of membranes which envelops the central nervous system. The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater. The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system....
