Question

give a brief account of machanism of synaptic transmission ​

Answer 1

Answer:

There are two ways of synaptic transmission. 1. Chemical transmission – When a nerve impulse reaches the end plate of axon, it releases a neurotransmitter (acetylcholine) across the synaptic cleft. ... The acetylcholine diffuses across the cleft and binds to the receptors present on the membrane of next neuron.

Answer 2

Answer

Synapse is a junction between two neurons. It is present between the axon terminal of one neuron.

There are two ways of synaptic transmission.

1. Chemical transmission
2. Electrical transmission

$\bigstar$ Chemical transmission :

• When a nerve impulse reaches the end plate of axon, it releases neurotransmitter across the synaptic cleft.
• This chemical is synthesized in cell body of the neuron and is transported to the axon terminal.
• This causes depolarization of membrane and initiates an action potential.

$\bigstar$ Electrical transmission :

• An electric current is formed in the neuron.
• This electric current generates an action potential and leads to transmission of nerve impulse across the nerve fibre.
