Question

Gap junctions allow direct communication or ionic flow between adjacent cells for a(n) ________ synapse, while synapses that use neurotransmitters to signal from the presynaptic to postsynaptic cell are called ________.

Answer 1

1. Electrical synapse

2. Chemical synapse

Step-by-step explanation:

The nervous system is composed of the billions of neurons which communicate with each other through the generated nerve impulse. The transmission of the nerve impulse depends on the movement of ions which generate an electric impulse.

The impulse is passed from one neuron to another neuron through the neuronal gaps called synapses.

The neurons which transmit the signal in the form of the electrical signal through the gap junctions between the neurons which allow the direct transmission of the signal. The synapse in such neurons is known as an electrical synapse.

The neurons which transmit the signal by converting the electrical signal to chemical signal in the form of neurotransmitter contain the synapse called chemical signals.

Thus, Electrical synapse and Chemical synapse are correct.
