White matter is primarily composed of myelinated axons, which are the long projections of neurons that transmit electrical signals. The myelin sheath, a fatty substance that surrounds and insulates these axons, gives white matter its characteristic color and enhances the speed of signal transmission. In contrast to gray matter, which contains neuron cell bodies and unmyelinated axons, white matter plays a crucial role in facilitating communication between different brain regions.
axon
The body.
The dendrites are the receiving part of the neuron.
dendrite
white matter
The parts are: the cervical, thoracic, lumbar, and pelvic regions. :)
gray matter
The white matter is located on the outer part of the spinal cord.
The axon, an elongated portion of the neuron, carries impulses to the muscles.
Motor Neuron
It doesn't matter if she wants to be white or not. Her father is white so she is part white.
The axon is the part of the neuron that can carry information for long distances.
Soma
Sensory neuron and motor neuron.
synapse
Cell Body
The synaptic cleft is the area of the neuron that secretes neurotransmitters.
