Synapses are:

A) intersections where the axons of one neuron meet the dendrites of another neuron.
B) where neurons make direct contact with one another.
C) chemical structures that allow dendrites to send their messages to axons.
D) the area where neurons determine whether a stimulus exceeds the absolute threshold or not.

Synapses

The junctions between neurons through which they communicate with each other using chemical or electrical signals.

Axons

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

Dendrites

The branched projections of a neuron that receive electrochemical signals from other neural cells and transmit these signals toward the cell body.
