A - dendrites
B - Nissl's granules
C - cyton or cell body
D - Schwann cell
E - Axon
F - Myelin sheath
H - Synaptic knob

Axon is a long fibre which is branched at its distal end and each branch ends into a bulb-like structure, which is termed as synaptic knob having synaptic vesicles filled with neurotransmitters. These neurotransmitters are released into the synapse between two consecutive axons. They are accepted by the receptors present on the membrane of the receiving axon.
