Neurology Unit AP Psychology Flashcards

8599117760	Dendrites	Receives information form Axon	0
8599125524	Nucleus (Soma)	The cells life support	1
8599135813	Axon	Sends messages away from the cell body	2
8599154771	Mylin Sheath	Helps speed up the messages and covers some axons	3
8599166502	Axon Terminals	Sends messages to other cells around each other	4
8599184333	Resting Potential	Negatively charged sodium ions inside Positively charged sodium ions outside	5
8599181525	Action Potential	Positive sodium ions rush in and trigger a domino effect down the axon	6
8599190603	Refactory Period	Positive sodium ions go back out	7
8599234309	Space between Neurons	Synapse	8
8599243793	Neurotransmitters	Unlock channels at the receiving site allowing ions into the receiving neuron	9
8599248364	Excitatory role:	positive ions allowed in causes firing	10
8599256330	Inhibitory role	negative ions allowed in prevents firing	11
8599262821	GABA	keeps brain calmed down and not firing out of control	12
8599266559	ACh (acetycholine)	Its function is motor movement and maybe memory	13
8599276620	Dopamine	Its function is motor movement and alertness.	14
8599279838	Serotonin	Function deals with mood control	15
8599285516	Endorphins	Function deals with pain control.	16
8599297940	Neuron Chain	Receptor Cells (antennae): - Skin on fingers Sensory cells (wires connected to radio) - Send impulse to spinal cord / brain Interneuron cells (radio) - Brain and spinal cord Motor cells (wires to speaker) - Back down arm to hand Effector cells (speaker) - Control muscles that retract fingers	17
8599304139	Peripheral Nervous System	Somatic Nervous System: voluntary control of skeletal muscles Autonomic Nervous System: controls the glands and muscles of internal organs Sympathetic nervous system arouses Parasympathetic nervous system calms	18
8599310985	Central Nervous System	Brain and spinal cord	19
8599318701	The Endocrine System	Glands that produce hormones that travel through the body to affect certain tissues Pituitary gland (master gland)	20
8599325212	Medulla	basic life support (breathing, swallowing, etc.)	21
8599328173	Reticular Formation	arousal center (consciousness)	22
8599333442	Thalamus	Sensory routing station except smell	23
8599337443	Cerebullum	Fine motor skills (balance and coordination)	24
8599344253	Amygdala	emotional center (rage and fear)	25
8599346887	Hippocampus	memory (if damaged you can remember old memories, but not new ones - "50 First Dates"	26
8599350186	Hypothalmus	bridge between neural and endocrine systems Directs hunger, thirst, body temp. Controls pituitary gland Linked to emotion Anger: FIGHT Scared: FLIGHT Hungry: FEED Sexual arousal: FORNICATE	27
8599358627	Frontal Lobe	higher order thinking	28
8599361444	Temporal Lobe	auditory processing	29
8599364618	Occipital Lobe	Vision processing	30
8599372950	Parietal Lobe	receives sensory input for touch and body position	31
8599375835	Motor Cortex	movement	32
8599378770	Broca's Area	expressive language *	33
8599382886	Werinkler's Area	receptive language *	34
8599388893	Corpus Callous	big body of nerve fibers that connects left and right brain *	35
8712976012	Brain Plasticity	Ability to modify itself after damage	36
8712989124	Sever Corpus Callous	Reduces seizures in epileptic patients	37
