Question

How a nerve impulse is transmitted across a synaptic cleft ?

Answer 1

The vesicles fuse to the membrane and the neurotransmitter is released into the gap between the two neurones (known as the synaptic cleft). The acetylcholine neurotransmitter then diffuses across the synaptic clefttowards the post-synaptic neurones membrane.

Answer 2

A nerve impulse is transmitted across a synaptic cleft.

Explanation:

• Pre-synaptic neuron and a post-synaptic neuron transmit the nerve impulse across a synaptic cleft by using the neurotransmitter diffusion.
• In simple term the transmission of impulse in the neuron is due to the electrical charges across the membranes.
• The first electric impulse travel through the "Axon" of the neuron then it reaches the dendrite by the help of chemical messengers.
• The vesicles then fuse together to the membrane and the neurotransmitter is inserted into the gap between the two neurons, these gaps are called as "synaptic cleft".
