AP Psych

• a branch of psychology concerned with the links between psychology and behavior
• behavioral neuroscientists
• pysiologiacal psychologists
• bio-psychologists

• a nerve cell: the basic building block of the nervous system
• there ate a lot of tyoes, but they have basically the same theme

• the brushy, branching extentions of a neuron that recieve msgs to conduct impulses towards the cell body
• (A)

• the extentoin of a neuron, extending in branching terminal fibers, through which msgs pass to other neurons or muscles or glands
• (B)

• a layer of fatty tissue segmentally encasing the fibers of neurons, enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next
• if the sheath desintagrates, communication to the muscles is slowed and you lose muscle control
• (C)

a neural impulse; a breif electrical charge that travels down an axon

• the level of stimulation required to trigger a neural response
• establishes an all or nothing synapse

the junction between the axon the tip of the sending neuron and the dendirte cell body of the recieving neuron.

• chem messages that traverse the synaptic gaps between neurons.
• when released by the sending neuron, neurotransmitters travel across the synapse and bind receptor sites on the recieving neuron, thereby influenceing wheter that neuron will generate a neural response

• a neurotransmitter that enables learning and memory and also triggers muscle contraction
• one of the best understood neurostransmitters

• natural opiate-like neurotransmitters linked to pain control and to pleasure
• can be triggered through exercise

• the center of cell body
• the battery basically

• Cell body/Cyton
• where the electrical charge happens (action potential)

• the clefts in the Mylin sheath
• speeds up message travel
• (F)

• long bracelet things that send the message out of the neuron into the synapse
• (G)

• balls of neurotransmitters in the axon terminal's terminal buttons
• (H)

• inside dendrites that pick up specific neurotransmitters and bind like a lock and key
• (I)

• the area btw the axons and dendrites where the chemical reactions happen
• (J)

• the bulb-like things at the inside of the axon terminals that contain vesicles
• (K)

• destressed
• a regrouping of a neuron so it is ready to fire again

less likely to fire

the resting period after the neuron fires for recouperation

sodium is pumped in while potassium is pumped out during action potential

• responsible for mood control
• effects sleep

• pain killer--blocks pain messages to the brain
• tied to movement and muscle control
• lack of it gives you Parkinson's
• too much gives you schizophrenia

• Alertness
• triggers nervous system (fight/flight)

makes inhibitory neurons fire (or block messages)

• makes exitedtory neurons fire
• (opposite of GABA)

• drugs that excite
• stimulants
• makeshift lock and key

• drugs that block an inhibitory action
• morphine
