Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A synapse is:
A
The meeting of the dendrite of one neuron with the axon terminal of another
B
The meeting of two axon terminals from different neurons
C
The meeting of two dendrites from different neurons
D
The meeting of two axon terminals from the same neuron
Explanation: 

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 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: -The axon terminal is adjacent to the dendrite of the postsynaptic-receiving-cell. This spot of close connection between axon and dendrite is the synapse. A single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells.

Detailed explanation-4: -The terminals release transmitter substances into a gap called the synaptic cleft between the terminals and the dendrites of the next neuron. The information is received by the dendrite receptors of the postsynaptic cell that are connected to it. Neurons don’t touch each other, but communicate across the synapse.

Detailed explanation-5: -The Synapse The place where the axon of one neuron meets the dendrite of another is called a synapse. Synapses are also found between neurons and other types of cells, such as muscle cells. The axon of the sending neuron does not actually touch the dendrite of the receiving neuron.
