Neurons are also called nerve cells . Parts of a Neuron 1. Cell Body (Cyton / Soma) Main part of neuron containing the cytoplasm and nucleus . Controls all activities of the neuron. Contains Nissl’s granules . Nissl’s Granules Granular structures present in cytoplasm. Help in protein synthesis . Present in cell body and dendrites. Absent in axon. 2. Dendrites Short, branched fibres arising from cell body. Receive stimuli or nerve impulses. Carry impulses towards the cell body . Important Point Dendrites contain Nissl’s granules . 3. Axon Long fibre arising from cell body. Conducts nerve impulses away from the cell body . Distal end of axon is branched. Axon Terminal Terminal branches end in swollen bulb-like structures called synaptic knobs . Synapt...
