Question

how do impulses get transmitted through the synaptic cleft​

Answer 1

Answer:

A nervous impulse is transmitted across the synapse from a pre-synaptic neurone to a post-synaptic neurone through the use of neurotransmitter diffusion. This changes the voltage in the neurone causing the voltage-gated calcium channels on the pre-synaptic neurone to open.

Answer 2

Explanation:

When a nerve impulse reaches the presynaptic terminal, it causes release of neurotransmitters into the synaptic cleft. These neurotransmitters diffuse through the synaptic cleft and bind to the receptors on post-synaptic neurons. This causes the transmission of nerve impulses from pre-synaptic to post-synaptic neuron.
