Question

Match the following columns.

Column 1	Column 2
Nerve impulse	Chemicals involved in the transmission of impulses at synapses.
Synaptic cleft	Gap between the presynaptic and post synaptic neurons.
Neurotransmitters	An electrical wave-like response of a neuron to a stimulation.

Answer 1

A. Nerve impulse III. Electrical wave-like response of a neuron to a stimulation

1. When a neuron is triggered, it produces an electric signal known as a nerve impulse.
2. This signal is subsequently passed between cells via synapses or connections.

B. Synaptic cleft II. The gap between the presynaptic and postsynaptic neurons

1. The small gap which separates two nerve cells is known as the synaptic cleft.
2. When the terminal end of an axon receives an impulse, the neurotransmitters are released into the synaptic cleft.

C. Neurotransmitters I. Chemicals involved in the transmission of impulses at synapses

1. Neurotransmitters are the chemical messengers produced by the nerve cells.
2. These are the molecules used by the nervous system to relay information between nerve cells, or from nerve cells to muscles
