question 6

Multiple Choice

Definitions:

Neuron

A nerve cell that is the basic building block of the nervous system, responsible for receiving, processing, and transmitting information through electrical and chemical signals.

Axons

Long, slender projections of nerve cells that transmit electrical impulses away from the neuron's cell body.

Axon Terminals

The very end of a branch of a neuron's axon, a region where neurotransmitters are stored before being released into the synaptic cleft.

Peripheral Nerves

Nerves located outside the brain and spinal cord that connect the central nervous system to limbs and organs, essentially serving as communication lines.
