Question | Answer |
what makes up the diencephalon | thalamus,hypothalamus |
3 parts that mke up brain stem | midbrain,pons,medulla oblongata |
cerebellum | little brain |
meninge | 3 layers of connective tissue surounds brain and spinal to form complete enclosure |
outer most meninge | dura matter |
function of dural sinuses | drainage of blood coming from brain tissue |
innermost meninge that follow contour of brain | pia mater |
how does CSF get from lateral ventricles to third ventricles | formina |
cerebral cortex | outer nervous tissue of the cerebral hemispheres in grey matter |
gyrus | folds forming elevated portions |
sylcus | shallow grooves of cortex |
what seperates the frontal and parietal lobes | central sulcus |
which lobe contains the primary sensory area that interprets impulses from skin | parietal lobe |
which lobe contains visual areas | occipital lobe |
where is the occipital lobe located | posterior to the parietal lobe and extends over the cerebellum |
person suffered damage to the auditory association will have problem with | interpreting sound |
person with damage to the broca area will have trouble with | producing speech |
what forms the lateral wall of the third ventricle | two parts of the thalmus |
what does the hypo thalmus control | body temp,water balance,sleep, appetite,some emotions(fear,pleasure) |
what shape is hippocampus and its functions | sea horse,learning and the formation of long term memory |
what reflexes does midbrain control | eye,ear |
3 techniques for studing the brain | ct scan,MRI,PET |
electroencephalograph | instrument used to study electrical activity in the brain |
encephalitis | inflamation of the brain |
hydrocephalus | abnormal accumulation of the CSF within the brain,normal in infants,treated with shunt to drain excess CSF |
causes of cerebrovascular accidents | blood clots,rupture of bllod vessel,cerebral hemorrage,stroke |
cerebral palsy | caused by brain damage befor or during birth process,diverse muscular disorders,slight weakness of lower extremity muscles,paralysis of all 4 extremities,speech muscles |
epilepsy | chronic disorder involving an abnormality of the brains electrical activity w/ or w/out apparent changes in nervous tissue |
most brain tumors are classafied as | gliomas |
epidural hematoma | bleeding between the dura matter and the skull |
what causes cerebral concussion | blow to the head or from sudden movementof the brain against the skull as in violent shaking |
effects of cerebral concussion | loss of conciousness,headache,dizziness,vomiting,paralysis and impared brain function |
what does alzheimers cause | sever intellectual impairment with mood changes and confusion |
multi infarct dementia and causes | accumulation of brain damage resulting from chronic ischmia,lack of blood supply,stroke |
parkinson disease characterized by | tremors,rigidity of limbs and joints, slow movement,impared balance |
what kind of impulses does olfactory carry | smell |
what does the vagus nerve control | larynx and pharynx |
what does the hypoglossal nerve control | muscles of the tongue |
what does oculomotor control | contraction of most eye muscles |
in glaucoma there is a increase pressure of the eye fluid on which nerve | optic nerve |
in bell palsy facial paralysis is caused by damage of which nerve | facial nerve |
trigeminal neuralgia | sever spasmadic pain affecting the fifth cranial nerve |
I (1)olfactory | sense of smell |
II (2)optic | impulses from eye to brain |
III(3)oculomotor | controls contraction of eye muscles |
IV (4)trochlear | supplies one eye ball |
V(5)trigeminal | impulses from eye,upper and lower jaw to brain |
VI(6)abducens | controls eyeball muscles |
VII(7)facial | controls muscles of facial expression,sensation of taste |
VIII(8)vestibulocochlear | impulses from hearing and equilibrium from inner ear |
IX(9)glossopharyngeal | impulses from tongue and pharynx,swalling muscles |
X(10)vagus | supplies most organs in thoracic and abdominal cavities,impulses to larnx and pharynx |
XI(11)accessory | controls muscles in neck and larynx |
XII(12)hypoglossal | controls muscles of tounge |
