Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
neurons communicate with one another at junctions called a ____
A
synapse
B
ion
C
molecule
D
channel
Explanation: 

Detailed explanation-1: -Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.

Detailed explanation-2: -The term “synapse” refers to the place where the terminal branches of one neuron’s axon connect to another neuron’s dendrite. Presynaptic and postsynaptic neurons join together to form the synapse. The connection between a neuron and a muscle is called the neuromuscular junction.

Detailed explanation-3: -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.
