|
Central Nervous System Comonents |
Brain + spinal chord |
|
|
Peripheral Nervous System Comonents |
Skeletal nervous system (sensory/afferent + motor/efferent) and Autonomic Nervous System (Sypmathetic + Parasympathetic) |
|
|
Role of GLia |
Supportive role and supply nutirnets and oygen to nerve cells. May also play role in communication in the brain |
|
|
Neuron Components |
Cell body, nucleus, dendrites, axons, myelin sheath, axon terminal, synapse |
|
|
Tract |
Nerves that are entirely within the brain or spinal chord. |
|
|
How does the cell body integrate IPSPs and EPSPs |
The potentials combine to create or prevent genesis of an action potential. |
|
|
Acetylcholine |
Involved in memory: too little---> Alzheimers |
|
|
Norepinephrine and Epinephrine |
Involved in wakefulness and mood. Mood elevating drugs increase norepinephrine release and relieve depresssion |
|
|
Dopamine |
Cognitive and Motor control: Too much --> schizophrenia. Too little --> parkinson's |
|
|
Serotonin |
Effects mood, involved in sleep and appetite SSRI's reduce uptake |
|
|
GABA |
Inhibitory. Too little = anxitey. Valium/ xanax increase |
|
|
Endorphins |
Involved in emotional behaviors. Involved in pain relief "natural opiates". |
|
|
Three families of neurotransmitters |
Amines, Amino Acids, and Peptides |
|
|
Members of the Amine Group |
Dopamine, epinephrine, norepinephrine, serotonin, acetylcholine |
|
|
Member of the Amino Acid Group |
Glutamate, GABA |
|
|
Peptides |
Large family; involved in emotions, stress, and pain perception. |
|
|
Examples of agonists |
Nicotine, morphine, tranquilizers |
|
|
Examples of Antagonists |
Caffeine, Botox, Thorazine |
|
|
Reuptake inhibitor example |
Prozac/cocaine |
|
|
Mechanism of Amphetamine |
Dopamine Agonist; increases the release of dopamine and blocks uptake |
|
|
Nicotine |
Acetylcholine Agonist |
|
|
Naloxone |
Used to treat opiate overdose and addiction. Acts as an opioid antagonist |
