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: -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-2: -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-3: -The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called neurotransmission. The space between the axon and the dendrites is called the synapse.

Detailed explanation-4: -Synapse Definition – Synapse is a junction between two neurons or a neuron and a target or effector cell such as a muscle cell. It permits the transmission of electrical or chemical signals. The synapse is formed between presynaptic and postsynaptic neurons.
