Question

A structure of a neuron is given in the diagram below. Select the incorrect statement with reference to the same.

• A. A typical neuron comprises of only three parts - A, C and E.
• B. B represents the granular bodies or Nissl's granules found in the cyton of the neuron.
• C. D are located on E, which secrete F.
• D. H possesses both dendrites and neurotransmitters.

Answer 1

Answer: (D)

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.
