Precursor a substance from which another substance is formed Neurotransmitter substance used to bridge the gap of the nerve synapse and transmit nerve impulses
Synapse gap between nerve cells
Nerve impulses traveling down the nerve must bridge this gap; they do this with neurotransmitters Neurotransmitters are released into the synapse from the upstream cell
The transmission of the nerve impulse continues when the next cell takes up the neurotransmitter, and the message continues on along the nerve The neurotransmitter allows the body to put a spin on the message contained in the nerve impulse, moderating or amplifying it by having more or less of each neurotransmitter as desired allows more control
Antigens foreign protein which trigger response by immune system
Antibody immune protein used to attack foreign proteins
When our immune system recognizes antigens on the surface of an invading organism, we respond with antibodies Energy
