What is the main function of a neuron?

The CNS includes the brain and spinal cord and is the site of information processing and control.The afferent nerve fibres transmit impulses from tissues/organs to the CNS.The efferent nerve fibres transmit regulatory impulses from the CNS to the concerned peripheral tissues/organsThe somatic neural system relays impulses from the CNS to skeletal muscles. The autonomic neural system transmits impulses from the CNS to the involuntary organs and smooth muscles of the body.Dendrites are short fibres that branch repeatedly and project out of the cell body of a neuron. They transmit impulses towards the cell body. The axons of a neuron transmit nerve impulses away from the cell body to a synapse or to a neuro-muscular junction.
