What are the three types of neurons?

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/organsBased on the number of axons and dendrites, neurons are divided into three types: multipolar (with one axon and two or more dendrites), bipolar (with one axon and one dendrite), and unipolar (cell body with one axon only).Nissl’s granules are granular bodies in the cell body of a neuron. They are composed of typical cell organelles and are also present in the dendrites. The synaptic knob is a bulb-like structure at the distal end of the axon of a neuron. It possesses synaptic vesicles containing neurotransmitters. Dendrites are short fibres that branch repeatedly and project out of the cell body
