How are messages transported in human brain 0?
Answers
Explanation:
Messages travel along a single neuron as electrical impulses, but messages between
neurons travel differently. 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.
When neurons communicate, an electrical impulse triggers the release of neurotransmitters
from the axon into the synapse. The neurotransmitters cross the synapse and bind to
special molecules on the other side, called receptors. Receptors are located on the
dendrites. Receptors receive and process the message.

What’s particularly interesting about neurotransmission is that each neurotransmitter
can bind only to a very specific matching receptor. A neurotransmitter binds to a receptor
in much the same way a key fits into a lock. After transmission has occurred, the
neurotransmitter is either broken down by an enzyme (a chemical that speeds up some of
the body’s processes) or is reabsorbed into the neuron that released it. The reabsorbed
neurotransmitters can be reused at a later time.
