AP PSYCHOLOGY

Detailed explanation-1: -The correct option is C. Nerve impulse. ∙ Nerve impulses are simply signals that are transmitted along nerve fibres (or neurons). It is the process by which neurons communicate with one another.

Detailed explanation-2: -An electric signal The nervous impulse is also called ‘action potential’. It refers to the electric signal produced by a neuron when stimulated. This signal is then transmitted by synapses, or connections between the cells.

Detailed explanation-3: -A nerve cell that carries messages is called a neuron. The messages carried by neurons are called nerve impulses.

Detailed explanation-4: -Nerve impulses are electrochemical events. Observed as an electrical event, a nerve impulse is called an action potential (AP) because it involves a change in electrical potential that moves along the nerve cell.

Detailed explanation-5: -A nerve cell (neuron) communicates with other cells through electrical impulses when the nerve cell is stimulated. Within a neuron, the impulse moves to the tip of an axon and causes the release of neurotransmitters, chemicals that act as messengers.
