NEET BIOLOGY

Detailed explanation-1: -The two adjacent neurons are never in direct contact. The microscopic gap exists between the two adjacent neurons and called synapse over which nerve impulses pass. This communication of nerve impulses are carried out by chemical messengers called neurotransmitters.

Detailed explanation-2: -Synapses are microscopic gaps that separate the terminal buttons of one neuron from receptors (usually, located on the dendrites) of another neuron. When neurons communicate, they release chemicals that must travel across this gap to stimulate the post-synaptic receptors.

Detailed explanation-3: -There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft.

Detailed explanation-4: -A synapse is the 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: -Neurotransmitters are released into the space between the two neurons. This space is called the synapse.
