Name the structure of neuron which conduct impulse.

Structure Of Neurons

Nerve fibres conduct impulses in

(a) Draw the structure of a neuron and label its nucleus, dendrite, cyton and axon. (b) Name that part of a neuron (i) which receives stimulus (ii) which transmits impulse

What is a nerve impulse ? Which structure in a neuron helps to conduct a nerve impulse (i) towards the cell body and (ii) away from the body ?

Name the following : (a) Neurons which carry impulses towards brain. (b) Process of neuron which carries impulses away from cyton.

Read the given statements and select the correct ones. (i)Autonomic neural system transmits impulses from the CNS to the voluntary organs and striated muscles of the body. (ii)Unmyelinated nerve fibres do not have Schwann cells which form the myelin sheath. (iii)Axonal membrane of a neuron while not conducting any impulse is comparatively more permeable to potassium ions (K^+) than to sodium ions (Na^+) (iv)A synapse is formed by the membranes of presynaptic neuron and a post synaptic neuron.

Name different parts of a neuron.
