Question

Transmission of the nerve impulse across a synapse is accomplished by the what?

Answer 1

Hey dude,

The receptors receive the neurotransmitters. These neurotransmitters stimulate action potential in the postsynaptic cell. Thus, transmission of nerve impulses across a synapse is through the release of neurotransmitters by the axon. Hence, the correct answer is (c) release of a neurotransmitter by an axon.

Answer 2

Answer:

(1) This transmission takes place with the help of

neurotransmitters.

(2) Once the neurotransmnitters bind to the

receptors of the post-synaptic cell, the action

is either excitatory or inhibitory depending on

the type of neurotransmitter.

(3) The enzyme like acetyl cholinesterase

destroys the neurotransmitter after the

transmission and the synapse is ready to

receive a new impulse.
