Detailed explanation-1: -Synapse, also called neuronal junction, is the point of contact between the terminal branches of the axon of a neuron with the dendrites of another neuron separated by a fine gap.
Detailed explanation-2: -The correct option is D. Synapse. The junction between the axon of one neuron and the dendrite of the next is called a synapse. Depending on the nature of transfer of information, there are two types of synapses-chemical synapses and electrical synapses.
Detailed explanation-3: -Synapse is a junction between two neurons or a neuron and a target or effector cell such as a muscle cell. It permits transmission of electrical or chemical signals.
Detailed explanation-4: -Axon terminal and synapse An axon terminal contains various neurotransmitters that are released at the small gap between two communicating neurons. This gap is called a synapse. The neuron that sends nerve impulses by releasing neurotransmitters via the axon terminal at the synapse is called a presynaptic neuron.
