Final answer:
The communication junction between two neurons is called a synapse. It involves the release and reception of neurotransmitters to transmit signals from one neuron to another.
Step-by-step explanation:
The communication junction between two neurons is called a synapse. It is the point at which the electrical signal from one neuron is transmitted to the next neuron through the release and reception of neurotransmitters. The synapse consists of the axon terminal of the presynaptic neuron, which releases the neurotransmitters, and the dendrites of the postsynaptic neuron, which receive the neurotransmitters.
For example, when an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the dendrites of the postsynaptic neuron, which generates a new action potential and continues the signal transmission.
The synapse is a crucial component of the nervous system, allowing for the transmission of information between neurons and enabling various functions such as sensory perception, motor control, and cognitive processes.
