AP PSYCHOLOGY

Detailed explanation-1: -Different neurons have different jobs. For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body to allow muscles to move.

Detailed explanation-2: -When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.

Detailed explanation-3: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.

Detailed explanation-4: -A synapse releases chemical signals, which are called neurotransmitters. These signals travel to another neuron to create a new electrical wave in that cell.
