GENERAL HISTOLOGY

Detailed explanation-1: -The spinal cord is composed of gray and white matter, appearing in a cross-section as H-shaped gray matter surrounded by white matter. The gray matter consists of the cell bodies of motor and sensory neurons, interneurons, and neuropils (neuroglia cells and mostly unmyelinated axons).

Detailed explanation-2: -Spinal nerves are mixed nerves that interact directly with the spinal cord to modulate motor and sensory information from the body’s periphery. Each nerve forms from nerve fibers, known as fila radicularia, extending from the posterior (dorsal) and anterior (ventral) roots of the spinal cord.

Detailed explanation-3: -Your spinal cord is a band of tissues, nerves and cells. A protective layer of bone called the vertebral column covers and protects your spinal cord. The bones in the vertebral column are called vertebrae (plural of one spine bone, a vertebra).
