Question

Choose CORRECT answer(s): The axon hillock is important because it is the site where the all of the following processes occur

Question 24 options: Could Be more than one Answer!

A	Summation of many postsynaptic potentials
B	Integration of information from multiple synapses with other cells
C	Activation of the voltage-gated sodium channels
D	Initiation of an action potential

Answer 1

Axon hillock: Is the part of the neurone where the cell body and the axon meets together.

A. Summation of many posynaptic potential occurs which are further being tranferred to the axon. So this option is ture.

B. The axon of the synapse receives information from multiple synapse and other cells and before being tranferred to the axon they all are integrated in the axon hillock. So this option is true.

C. Activation of voltage gated ion channels depends on the pre-synaptic neurotransmitters which results in depolarization of the post-synaptic neurone and this depolarization pass through the axon hillock and cause oprning of Na+ channels.So this option is wrong.

D. The initiation of action potential depends on the releasing on the releasing of the neurotransmitters from the pre-synaptic neurone.So this option is wrong.

So the correct answers are- (A) & (B)
