AP PSYCHOLOGY

Detailed explanation-1: -Axon is branched distally. The branch ends are expanded to form synaptic knobs. These knobs possess neurotransmitters containing synaptic vesicles. Axon carries the impulse away from the cell body.

Detailed explanation-2: -The dendrites carry impulses toward the cell body. The axon carries impulses away from the cell body. Axons and dendrites are sometimes called nerve fibers. A bundle of nerve fibers is called a nerve.

Detailed explanation-3: -A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that ca rry the nerve impulse to the next cell.

Detailed explanation-4: -The electrical impulse is generated be creating an imbalance of positive and negative charges across the axon’s membrane. When the axon is resting there is unequal concentrations of ions (charged atoms) both inside and outside of the axon.
