Discuss the key structural features of a neuron. What is the role of neurotransmitters?
ANSWER:
The brain is made up of neurons. The dendrites are the component of neurons that receive signals from other nearby neurons. The axons contain neurofibers. These neurofibers carry information inside the neuron from the dendrites to the terminal branches, which are the endpoints of the neuron. Terminal branches release chemicals called neurotransmitters. Because neurons do not touch, it is these neurotransmitters that cross the synapse and are received by the dendrites of next nearby neuron.
