| 2995022744 | Building blocks of nervous system | Neurons | 3 | |
| 2995022745 | 3 things glial cells do | 1. Protect & nourish neurons 2. Remove waste from nervous system 3. Influence growth | 4 | |
| 2995022746 | 3 neuron parts | 1. Dendrites 2. Soma (cell body) 3. Axon (transmits impulses) | 5 | |
| 2995022747 | Transduction | Converting external energy into an impulse | 6 | |
| 2995022748 | Throbbing sensation after cut | Inhibitory potential | 7 | |
| 2995022749 | Natural pain killers/inhibitory potential | Endorphins | 8 | |
| 2995022750 | Transduction TO brain/sensory | Afferent neurons | 9 | |
| 2995022751 | Transduction FROM brain/motor | Efferent neurons | 10 | |
| 2995022752 | Released in brain/ neurological stability/ Parkinson's from lack of this | Dopamine | 11 | |
| 2995022753 | Released in brain or heart/ hippocampus/ lack = Alzheimer's | Acetylcholine | 12 | |
| 2995022754 | Excitatory potential | Heart | 13 | |
| 2995022755 | Inhibitory potential | Brain | 14 | |
| 2995022756 | Nervous system acts on this/ if energy is strong enough to cause impulse, that impulse will fire 100% or none at all | All-or-none principle | 15 | |
| 2995022757 | 1/1000th of a sec before can fire again | Absolute refractory period | 16 | |
| 2995022758 | Central nervous system | Brain & spinal cord | 17 | |
| 2995022759 | Stem cells can be developed into new brain cells/ 13 years | Human genome project | 18 | |
| 2995022760 | Science of discovering how to create new brain cells(neurons) | Neurogenesis | 19 | |
| 2995022761 | Brain can be modified by feedback from environment & altered bc of social success (responds physically to experience) | Plasticity | 20 | |
| 2995022762 | Only human organ isolated & encased in bone; sound & light proof; floats in cerebral spinal fluid; 3 lbs | Human brain | 21 | |
| 2995022763 | Brain capacity | 7-20% | 22 | |
| 2995022764 | Take over if brain is damaged | Association areas | 23 | |
| 2995022765 | Records brain waves activity in monitor | EEG | 24 | |
| 2995022766 | Diagnose brain abnormalities; rotating x-Ray scanner | CAT scan | 25 | |
| 2995022767 | Cross-section of brain; map of brain depicted in colors | PET scan | 26 | |
| 2995022768 | Most advanced; superior bc higher resolution of image; not exposed to x-Ray hazards; multiple angles of brain | MRI | 27 | |
| 2995022769 | 6 critical structures of brain (limbic system) | 1. Brain stem 2. Thalamus 3. Amygdala 4. Cerebellum 5. Hippocampus 6. Hypothalamus | 28 | |
| 2995022770 | Major life support center; crucial to life; PONS regulates sleep; RAS determines length of sleep; medulla regulates & controls breathing, blood pressure, heart rate, & muscle control | Brain stem | 29 | |
| 2995022771 | Sensory relay station for all incoming sensory messages; switchboard; all senses go thru this except olfactory (smell) which bypasses it | Thalamus | 30 | |
| 2995022772 | Regulates & controls very strong emotions (aggression) | Amygdala | 31 | |
| 2995022773 | Back of brain; controls body balance | Cerebellum | 32 | |
| 2995022774 | Info processor where memories are stored, created, & retained | Hippocampus | 33 | |
| 2995022775 | Regulate & control body temp & other activities of hormonal system & basic drives & need for oxygen & where pain/pleasure centers are found | Hypothalamus | 34 | |
| 2995022776 | 4 major lobes of brain | 1. Frontal 2. Parietal 3. Oxypital 4. Temporal | 35 | |
| 2995022777 | Largest set of lobes; body movement, speech, & cognitive functions; covering is motor cortex; most of brain association areas are here; Broca's area (speech)(Broca's aphasia from damage to area- slow speech) | Frontal | 36 | |
| 2995022778 | On top behind frontal; tactile functions (touch, body temp, pleasure, pain); covering is somatal sensory cortex (body sensory) | Parietal | 37 | |
| 2995022779 | Back of brain; regulates & correlates visual functions; association areas related to visual memory; covering is visual cortex | Oxypital | 38 | |
| 2995022780 | Sides of brain; processing auditory stimuli (hearing); covering is auditory cortex; Wernicks area (Wernicks aphasia = can't understand spoken language & difficulty finding proper words to express self) | Temporal | 39 |
