GENERAL HISTOLOGY

Detailed explanation-1: -Cauda equina – The collection of nerves at the end of the spinal cord that resembles a horse’s tail. Cervical spine – The neck region of the spine consisting of the first seven vertebrae. Coccyx – More commonly known as the tailbone, this is a bony structure in the region of the spine below the sacrum.

Detailed explanation-2: -The cauda equina consists of the spinal nerve roots L2-S5 and the coccygeal nerve. It lies within the distal third of the vertebral canal and extends into the sacral canal.

Detailed explanation-3: -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-4: -Eight cervical nerve pairs (nerves starting in your neck and running mostly to your face and head). Twelve thoracic nerve pairs (nerves in your upper body that extend to your chest, upper back and abdomen). Five lumbar nerve pairs (nerves in the low back that run to your legs and feet). More items
