Answer:
The central nervous system (CNS) is composed of the brain and spinal cord and is responsible for coordinating and controlling body functions. The peripheral nervous system (PNS) is composed of nerves and ganglia outside of the brain and spinal cord and is responsible for connecting the CNS to the rest of the body.
Motor neurons are responsible for transmitting signals from the CNS to muscles and other effector organs to produce a response. Sensory neurons are responsible for transmitting signals from sensory organs and receptors to the CNS.
An axon is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body. A dendrite is a short, branching projection of a nerve cell that conducts electrical impulses toward the cell body.
