• Neurotransmitter -Chemical messenger that carries impulses across the synaptic gap across transmitters

Fast Fact - Abuse of the drug ecstasy, inhibits natural production of the neurotransmitters Endorphins; when off of the drug, depression is a chronic disorder

Action Potential -electrical charge that travels down its axon

Reuptake - the sending neuron reabsorbs the excess neurotransmitters from the synapse

I . THE NERVOUS SYSTEMThe system that regulates the body's responses to internal & external stimuli. Consists of the

A. Central Nervous System

B. Peripheral Nervous System

- consists of the1. BRAIN & 2. SPINAL CORD - column of nerves within the spine

that transmits messages to & from the brain.

- communicates between the central nervous system & all parts of the body.1. Somatic Nervous system - transmits senses to the

central nervous system. temp – pressure2. Autonomic Nervous System(ANS) -regulates the

body’s vital functions, Ex. heart beat, breathing, digestion, & blood pressure

Fast Fact:The spinal cord is as thick as a thumb.
