What is a synapse?
A
The space between the axon of one neuron and the cell that is receiving a signal
B
a chemical signalling molecule
C
a type of neuron
D
a part of the axon
Explanation: 

Detailed explanation-1: -Synapse – The junction between the axon of one neuron and the dendrite of another, through which the two neurons communicate.

Detailed explanation-2: -The axon terminal has vesicles filled with neurotransmitters ready to be released. The space between the axon terminal of one cell and the dendrites of the next is called the synapse.

Detailed explanation-3: -Axodendritic. A connection formed between the axon of one neuron and the dendrite of another. These tend to be excitatory synapses. Axosomatic. A direct connection between the axon of one neuron to the cell body of another neuron.

Detailed explanation-4: -A synapse is a small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon of a presynaptic (sending) neuron to the dendrite of a postsynaptic (receiving) neuron. It is referred to as the synaptic cleft or synaptic gap.

Detailed explanation-5: -The neurotransmitters carry the message with them into the synapse. The synapse is the space between the axon of one neuron and the dendrites of another neuron. neuron, called receptors. The neurotransmitters fit into the receptors like keys in locks.
