Section 1

Question Answer
An Action Potential Occur Where?ONLY in the Axons-->Extension of the cell body..only one per cell..has myelin shealths
What is Node of Ravier?It is the area where action potentials move after mylein shealth.
What is Refactory?The area of the axon where the Action Potential moved FROM
What is the function of the Nervous System?1. To CONNECT all parts of the body to the CNS 2. To PROCESS the incoming data 3. To SEND signals back to the rest of the body to their activity
What is the neuron before the synapse of an action potential occurs?Pre-synaptic Neuron
What is the neuron after the synapse of action potential?Post-synaptic Neuron
For a neuron to connect/transmit information what 2 things are needed?Synapse and Neurotransmitter
Name the 2 different responses of a neuron connectionExcitory affect or Inhibitory affect
General steps of Signal Transmission1.The signal reaches the end of the axon terminal (Pre-synaptic neuron) 2. The neurotransmitters are released by exocytosis of vesticle packages
What causes a stronger impulse?Neurotransmitter concentration
Products of metabolism-->Acetycholine
Modified amino acids-->momoamine
Unmodified amino acids-->Glycine and GABA
Peptides-->Short chain of amino acids

Section 2

Question Answer
L-Trytophan, produces what Serotonin when modified
Serotonin (CNS) regulatesanxiety, emotions, appetite
Catecholamine, produces whatEpinephrine/Norepinephrine and Dopamine
Epinephrine and Norepinphrine controlsCNS--conscience arousal and PNS-muscle activity
Epi and Norepinephrine are also called what response"fight-or-flight" response
Dopamine controlsCNS-behavior and reward systems and PNS-skeletal musle coordination
Name the monoaminesL-tryptophan, Serotonin, Catecholamine, Epi/Norepinephrine, and Dopamine
Name the unmodified amino acidGlycine and GABA
What is Glycine functionSequencing skeletal muscle control in the SPINAL CORD of the CNS
What is GABA's functionCoordination of muscle sequence/order of the CNS in our BRAIN
What is a peptideA short chain of amino acids that are involved in sensory perception
What neurotransmitter is blocked at the neuro musclular junctionAcetycholine-->Paralysis for surgery, Botox, Nerve gas, Botulism, and Totanus
Substance in chocolate that elevates momentarilySerotonin
High in meats L-Tryptophan
Prototype for SerotoninProzac
Parkinson's disease, depression, schizophreniaDopamine
Binds to all receptors in the monoamine familyCocaine
