The ventral horn of the spinal cord contains motor neurons that transmit signals from the brain to the muscles, enabling voluntary movement.

The spinal cord's main role is to process sensory information from the body and transmit it to the brain, as well as relay motor commands from the brain to the muscles.

The meninges, consisting of three layers (dura mater, arachnoid mater, and pia mater), protect and support the spinal cord.

Astrocytes are not neurons but glial cells that provide support and nourishment to neurons in the central nervous system.

An unconditioned reflex is an innate, automatic response to a stimulus that does not require learning or conditioning.

The dorsal horn of the spinal cord contains sensory neurons that receive and transmit sensory information from the body to the brain.

The central canal is a narrow, fluid-filled cavity that runs through the center of the spinal cord.

The sacral region is part of the vertebral column, not the spinal cord.

Conduction is the process by which nerve impulses are transmitted along the spinal cord through the axons of neurons.

Car accidents, sports injuries, and falls are all common causes of spinal cord injuries.

Spinal cord injury refers to damage or dysfunction of the spinal cord, often resulting in loss of motor or sensory function.

Stem cell therapy is still an experimental treatment for spinal cord injuries and is not yet widely available.

The myelin sheath is a fatty layer that surrounds the axons of neurons in the spinal cord, providing insulation and increasing the speed of nerve impulse conduction.

Hormone production is not a function of the spinal cord.

Amyotrophic lateral sclerosis (ALS) is a progressive neurological disease that affects motor neurons in the spinal cord and brain.
