front 1 cluster of somas or ganglia in the brain | back 1 Nuclei |
front 2 Change is getting you closer to threshold,Causes membrane potential to go up due to it being more positive,stimulus would cause opening of chemically gated Na+2 channels/calcium ions which depolarizes,channels close and go resting | back 2 excitatory |
front 3 CAN NOT GET EXCITED AGAIN NO MATTER HOW HARD IT IS STIMULATED DUE TO OPEN VOLTAGE GATED IONS CHANNELS, TO START NEW ONE THE MUST BE CLOSED | back 3 ABSOLUTE REFRACTORY PERIOD |
front 4 starts with one and and each one communicates with 2 more each time,single input increasing output | back 4 Divergent |
front 5 Change gets you farther away from threshold,Opening ion channels will get more negative, Causes membrane potential to go down due to it being more negative,stimulation would release neurotransmitter that opening on chemically gated K+ channels | back 5 Inhibitory |
front 6 PERIOD DURING WHICH ONLY EXTRAORDINARY STRONG STIMULATION CAN LEAD TO NEW AP,MEMBRANE POTENTIAN IS MORE NEGATIVE THAN POSITIVE SO IT IS STRONGER | back 6 RELATIVE REFRACTORY PERIOD |

front 19 Primarily somatosensory +association,located at_ | back 19 parietal lobe |
front 20 Frontal eye field | back 20 in charge of eyeball movement |
front 21 Broca’s | back 21 in charge of movement of tongue in speech |
front 22 Primary visual+association,located at | back 22 Occipital lobe |
front 23 Language area,located in _ and it is important for _ | back 23 temporal lobe-associated with broca’s & wernicke’s |
front 24 Prefrontal cortex,Located in_ and it is important for _ | back 24 frontal lobe-In charge of personality,thoughts,judgments etc. |
front 25 Visceral sensory association,located in_ | back 25 insula |
front 26 All myelinated axons are- | back 26 White matter |
front 27 communicate within the same hemisphere | back 27 Association fibers |
front 28 connecting/communicating between the 2 hemispheres | back 28 Commissure [bridging] |
front 29 communicate between upper and lower parts of brain hemispheres | back 29 Projection fibers |
front 30 undesirable movement | back 30 Huntington disease |
front 31 tremor,typical parking zone | back 31 Parkingson |
front 32 doesn’t show symptoms until individual has kids,family history helps to make sure child doesn’t have effective gene | back 32 neurodegernative diseases of brain |
front 33 choroid plexus-source for cerebrospinal fluid (CFS)+Pineal gland-secreting melatonin | back 33 Epithalamus |
front 34 Central main relay station of the brain + its function is sorting,organizing and editing incoming signals | back 34 Thalamus |
front 35 Hypothalamus:Master of visceral control and homeostases,gathers information from blood to intergrate and determine what has to be done,regulation of everything. BP,BT etc. Regulation of endocrine function; CONTROL OF FEELING BEHAVIOR: feeling hungry/thirsty | back 35 Hypothalamus |
front 36 Neurons are amitotic Which means | back 36 They don’t regenerate themselves |
front 37 Spinal nerves are | back 37 mixed nerves |
front 38 both loss of voluntary and involuntary control | back 38 Flascid paralysis |
front 39 damage to motor cortex,only loss of voluntary movement | back 39 Spastic paralysis |
front 40 Parlyzez is | back 40 loss of control |
front 41 No neurilemma,dense collections of myelinated fibers is | back 41 White matter |
front 42 No neurilemma,mostly soma and unmyelinated fibers | back 42 Gray matter |
