Nerve cell vocab: dendrite? axon? myelin sheath? node? "blister packs"? | dendrite: receive message axon: carry impulse away from cell body myelin: insulator of axon tail node: exposed area bn myelin Pack: neurotransmitters are stored |
saltatory conduction? cable conduction? | salt: electrical impulse jump from node to node, quick cable: electrical impulse thru axon, not jump, not myelin, slower |
what is the functional unit of the brain? Can they regenerate? two types? | neuron, yes myelinated(motor run from brain to body, saltatory), unmyelinated(sensory from body to brain, cable) |

What makes up the BBB to protect body? What freely moves in/out BBB? | BBB: astrocytes with macrophages and allows glucose/O2 |
the neurotransmitter that is excitatory in the ANS in many parts of brain | acetylcholine |
neurotransmitter, excitatory in SNS in brain stem, hypothalamus and affects mood and overall activity | norepi |
neurotransmitter, in basal ganglia, inhibitory affecting behavior, fine mvmt and decr in parkinson's? Incr causes? | dopamine psychosis |
neurotransmitter, excitatory, inihibits pain, gives pleasure, body' Morphine found in spine, brain stem, thalamus | Enkephalin, endorphin |
neurotransmitter, inhibitory and has increase in alcohol withdrawal, Versed, benzo's | GABA |
What comprises the CNS | brain stem, spinal cord |
What is the seat of consciousness? | cerebrum |
Cerebrum controls? | voluntary mvmt, higher fx: memories, emotions, IQ |
What separates the two hemispheres of the brain | corpus collosum |
The Diencephalon controls hormones and sensory input, what r two important glands are part of this | thalamus hypothalamus |
the thalamus acts as a _______ for nerve impulses? The hypothalamus is the _______ for all ANS systems? | Tha: sensory relay, switching station Hypo: master control/gland, reg. temp, pituitary gland, water balance, circadian rhythms, hunger and appetite |
What two problems can occur when the water balance of the hypothalamus is disturbed? | Diabetes Insipidus and SAIDH |
The frontal lobe is the largest and responsible for | judgement, personality, inhibitions, foresight |
Located in the back of the frontal lobe is ________ and controls _________. It is contralateral. | motor strip, voluntary motor fx |
What is the are for motor area of speech? Which side is it typically located? Define expressive aphasia and dysphasia. | Broca's area on left. Exp Aph: inability to speak dys: difficulty speaking |
This lobe interprets from the thalamus sensory information in the brain. | parietal lobe |
The sensory strip is located where? | front of parietal lobe, next to motor strip |
The temporal lobe is location of what? | auditory, taste, smell receptive areas, near Broca's area |
This special area controls hearing and understand of what we heard | Wernicke Area |
What is auditory receptive aphasia | in ability to understand the sounds of speech. Ability to speak is not affected. Difficulty naming objects...Wellow for yellow. Anxiety makes worse |
What lobe controls visual interpretation | Occipital lobe |
What is the term for losing ability to both understand and communicate? | Global Aphasia |
What happens in the midbrain? Pons? medulla oblongata? | mid: auditory/visual reflexes, sleep/wake, temp reg. pon: sleep, resp, swallowing, bladder control, hearing, eye mvmt, facial sensation, posture Med: cardiac, resp, vomit, vasomotor, autonomic fx, cranial nerves IX - XII |
What happens in cerebellum? | equillibrium, posture, muscle tone, proprioception. Romberg test for ataxia, balance |
What are three layers of brain from outter to inner | Dura Mater: outter cover CNS Arachnoid Mater: produces CNF by plexus, villi absorb CSF Pia Mater: hugs brain, circle of Willis |
What is the purpose of CSF? What are pressures of recumbent position? sitting? | cushioning, sterile, number tubes in spinal tap, no blood after 1st recumbent: 60-180 sit: 200-350 |
What is the largest art in the brain? | middle cerebral art where most strokes are |
What is most important for brain activity to exist? | glucose and oxygen |
What is unique about cerebral veins? | no valves, so blood flow in vv depends on gravity and BP |
How can you bypass BBB? | intrathecal |
TIA vs RIND | TIA: reduction of blood for up to 24hr and resolves self. RIND: ischemia lasts 24-48h |
Describe the 31 pairs of nerves which are part of the peripheral nervous system. | 8 cervical...5th effect diaphragm 12 thoracic 5 lumbar 5 sacral 1 coccygeal |
Where does spinal cord end and where is spinal tap done? | L2 L3-L4 |
Sensory nerves travel how? Locate where on horn? What two tests are done to test this? | from the body to brain(ascending) and located posterior horns(upper). Two point location and stereognosis(ability to recognize object by feel) |
motor pathways are locate where? How do they travel? | anterior horns(lower) and travel from brain to body(descending) |
Motor pathways have two levels describe them | upper: go from brain down spine. Damage is usually due to stroke/trauma and leave pt w/o mvmt of muscle, but have clonus(bouncing) lower: from spine to muscles. Pt feel like muscle should work, but not and damage is to spinal cord |
How does a pain signal travel in the body? | step on nail, sensory detects stimuli to move body. Brain send signa thru motor pathway to inhibit mvmt. |
What are the 12 cranial nerves? | On Old Olympus Towering Tops A Finn and German Viewed Some Hops...olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, hypoglossal |
Which one are somatic/motor/both | Some say marry money but my brother says big boobs matter more. |
I Olfactory? Test? II Optic? III Oculomotor? | olf: (S) smell Opt: (S) visual acuity and fields Ocu: (M) moves eyes/lids, papillary constriction, lens accomodation |
IV Trochlear V Trigeminal VI Abducens | Troch: (M) muscles that move eyes up/d Tri: (B)facial sensation, corneal reflex Abd: (M)musclese that move eyes lateral |
VIII Vestibulocochlear IX Glossopharyngeal X Vagus XI Spinal Accessory XII Hypoglossal | Vest: (S)acoustic, hearing equilibrium Gloss: (B)taste, swallowing Vag:(B)slows heart, bronchoconstrict Sp Acc: (M) shrug shoulder Hypo: tongue |
