The white matter of the spinal cord contains c myelinated nerves, while the gray matter contains d motor neurons and sensory neurons.
To elaborate, white matter is primarily made up of myelinated axons, which are long projections of nerve cells that allow for the rapid transmission of electrical signals between different regions of the nervous system. This myelination gives the white matter its characteristic color. In contrast, gray matter consists of neuronal cell bodies, dendrites, and unmyelinated axons. It is where synapses occur, allowing for processing and integration of information. The presence of motor and sensory neurons in the gray matter facilitates movement and sensory input reception. Understanding these distinctions helps in grasping how the spinal cord functions overall.
