Central Nervous System (CNS) - ANSWER-composed of the brain and spinal cord.
Peripheral Nervous System (PNS) - ANSWER-is made up of nerves that branch from
the CNS to the rest of the body. There are two parts: the somatic system and the
autonomic system.
Somatic System - ANSWER-connects the nerves of the CNS to the skin and skeletal
muscles.
Autonomic System - ANSWER-connects the nerves of the CNS to the organs of the
body. Function involuntarily and has two subdivisions: the sympathetic division and the
parasympathetic division.
Sympathetic Division - ANSWER-involves the fight or flight response.
Parasympathetic Division - ANSWER-returns the body processes to normal after the
sympathetic division has been engaged.
Neurons - ANSWER-are the cells that are responsible for the transmission of
information and has one axon, but may have many dendrites.
Cell Body - ANSWER-processes called axons and dendrites.
Synaptic Knobs - ANSWER-end of each axon and holds neurotransmitters in its
vesicles.
Chemical Receptors - ANSWER-end of the dendrites.
, Synaptic Cleft - ANSWER-space between neurons.
Synapse - ANSWER-junction between neighboring neurons and is filled with a type of
fat that acts as an insulator.
Neurotransmitters - ANSWER-Cell body manufactures these chemicals which transmit
nerve impulses between cells.
Presynaptic Neuron - ANSWER-cell which releases the neurotransmitter.
Postsynaptic Neuron - ANSWER-cell which receives the neurotransmitter.
Excitatory - ANSWER-which means that it helps start the transmission of a nerve
impulse.
Inhibitory - ANSWER-which means that it inhibits the transmission of nerve impulse.
Acetylcholine - ANSWER-(excitatory neurotransmitter): muscle movement
Norepinephrine - ANSWER-(excitatory neurotransmitter): arousal, moods, memory
formation
Dopamine - ANSWER-(inhibitory and excitatory neurotransmitter): body movement,
pleasure, reward
Serotonin - ANSWER-(excitatory neurotransmitter): emotion, mood, sleep, temperature
regulation
GABA (gamma-aminobutyric acid) - ANSWER-(inhibitory neurotransmitter): motor
behavior (deficit may result in convulsions)
Glycine - ANSWER-(inhibitory neurotransmitter): spinal reflexes, motor behavior
Enkephalins and Endorphins - ANSWER-(inhibitory neurotransmitter): pain reduction,
pleasure
Receptor Site - ANSWER-Many drugs can bind to this and mimick the effects however
some drugs with bind to this but will not activate it.
Medulla Oblongata - ANSWER-Lowest part of the brain. Made up of ascending and
descending nerve fibers that connect the spinal cord to the brain. Controls vital life-
sustaining functions such as heartbeat, breathing, blood pressure, and digestion. Drugs
such as opiates and barbiturates can depress the function of the medulla and even
cause death.
