Explain the following processes: (d) Transmission of a nerve impulse across a chemical synapse
The nerve impulse is usually transmitted through a gap called synaptic cleft by changing the action potential into a chemical signal where the neurotransmitters diffuse across the synaptic cleft and bind to receptor molecules triggering the second cell that starts a new action potential once the action potential is initiated in the post-synaptic neuron, the impulse is transmitted from one neuron to another
