Question

The junction formed by two neurons is called ______ and they communiacte by releasing a chemical called ______.

• A. synapse, hormones
• B. axon, hormones
• C. synapse, neurotransmitter
• D. cell body, neurotransmitter

Answer 1

The correct option is C

synapse, neurotransmitter

A nerve impulse is carried through the axon towards the synaptic bulb. The dendrite of a receiving neuron picks up the impulse. The junction formed between the synaptic bulb of one neuron and the dendrite of another neuron is known as a synapse. The synapse helps to regulate the speed and direction of impulses. Chemicals known as the neurotransmitters are secreted by the synaptic bulb. It facilitates the transfer of the impulses between two neurons. Acetylcholine and dopamine are examples of these neurotransmitters.
