PSYCHOLOGY NEURON TEST Flashcards

2129404590	Soma	Contains cell nucleus, DNA, controls protein manufacturing	0
2129408331	Dendrites	Information collectors, receive inputs	1
2129413661	Axon	tube like structure, carries messages	2
2129416498	Terminal Button	Where the neuron releases chemicals to communicate w other neurons	3
2129466425	Myelin Sheath	White fatty casing on axon, produced by schwann cells	4
2129469716	Why are neurons important?	basic fundamental building block	5
2129477507	Why do people suffer from multiple sclerosis?	they have a lack of myelin sheath	6
2129484039	Neurogenesis	creation of neurons from stem cells	7
2129487717	Neuromigration	process by which neurons travel to certain places in brain during early development	8
2129501872	Aptosis	use it or lose it	9
2129508818	Action potential	the electrical message being sent down the axon from the dendrites to the terminal buttons	10
2129513811	Threshold	Each neuron has a set number of receptor sites	11
2129515374	All or none response	if all receptor sites are not filled, the neuron will not fire an action potential	12
2129519744	Ion	a molecule with an electrical charge	13
2129527256	Polarized( Resting State)	When a neuron has a negative charge inside and positive charge outside	14
2129581473	Semi permeable cell wall	Only certain molecules can pass through the cel membrane of a neuron	15
2129592234	Depolarized(Excited State)	Cell membrane opens and sodium floods in ion exchange causes production of an action potential	16
2129599078	Refractory Period (Recharging)	When potassium gets kicked out of the neuron and the neuron produces more protein	17
2130989520	Speed of stimuli	Diameter of the axon presence of myelin	18
2131003133	Intensity of Stimuli	Frequency of action potentials Amount of neurons Stimulated	19
2131004548	Synapse	the space between 2 neurons where the chemical messages are exchanged	20
2131007890	Pre-Synaptic Neuron	The neuron sending the message	21
2131009077	Post-Synaptic Neuron	The neuron receiving the message	22
2131012384	Inhibitory	calms the brain and creates balance	23
2131017628	Excitatory	Excites the brain	24
2131071808	Acetycholine	Small muscle movement memory	25
2131074169	Dopamine	Pleasure Movement Sensory	26
2131075421	Serotonin	Mood	27
2131076039	Gaba	Major Inhibitory Stops anxiety	28
2131076530	Melatonin	Induces Sleep	29
2131078534	Norepinephrine	Flight or Fight	30
2131082371	Glutamate	Most common excitatory	31
2131088387	Diffusion	the neurotransmitter drifts out so it cannot activate receptor	32
2131092544	Enzymatic Degradation	an enzyme changes the structure so it is not recognized by the receptor	33
2131096382	Glial Cells	Remove the chemical from the synapse	34
2131107302	Reuptake	goes back into the pre-synaptic neuron to be recycled	35
2131108670	Schizophrenia	A group of disorders characterized by confused disconnected thoughts, emotions and perceptions through hallucinations and delusions	36
2131115278	Positive Schizophrenia	added after onset delusions	37
2131116436	Negative Schizophrenia	lose after onset lose mobility	38
2131117697	Paranoid Schizophrenia	Presence of auditory hallucinations or prominent delusional thoughts about persecution or conspiracy	39
2131126504	Disorganized Schizophrenia	Disorganization of thought process	40
2131129313	Catatonic Schizophrenia	Dramatic Reduction in activity to the point where voluntary movement stops	41
2131137053	Undifferentiated Schizophrenia	Symptoms but not sufficient to classify into a subtype	42
2136786300	Blood-Brain Barrier	Semi-Permeable membrane of blood vessels; that is, it allows some materials to cross, but prevents others	43
2136794074	Functions of Blood Brain Barrier	Protects brain from foreign substances Protects brain from other chemicals Maintains constant environment	44
2136796330	Agonist	Fake me out drug tricks BBB	45
2136797367	Antagonist	Blocks receptor sites	46
2136797898	Reuptake Prevention	Blocks reuptake of the neurotransmitter into the presynaptic neuron	47
2136800535	Blocking Enzymatic Degradation	Antidepressant	48
2136801875	Parkinson's treatment	L-Dopa	49
