Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what is a synapse?
A
the place where neuron transfers an impulse to another structure.
B
an action that is performed as a response to a stimulus and without conscious thought.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The synapse is formed between presynaptic and postsynaptic neurons. It is known as the neuromuscular junction between a neuron and muscle. The conduction of nerve impulses from an axon terminal of a neuron to dendrites of the next neuron occurs through a synapse. It can be electrical or chemical.

Detailed explanation-2: -The place where an axon terminal meets another cell is called a synapse. This is where the transmission of a nerve impulse to another cell occurs.

Detailed explanation-3: -Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron-another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.

Detailed explanation-4: -The synapse, rather, is that small pocket of space between two cells, where they can pass messages to communicate. A single neuron may contain thousands of synapses. In fact, one type of neuron called the Purkinje cell, found in the brain’s cerebellum, may have as many as one hundred thousand synapses.

Detailed explanation-5: -The places where neurons connect and communicate with each other are called synapses. Each neuron has anywhere between a few to hundreds of thousands of synaptic connections, and these connections can be with itself, neighboring neurons, or neurons in other regions of the brain.
