: uses memories of learned movement to coordinate motor activitiesVisual association area: visually recognizes and interprets objectsAuditory association area:recognizes soundAssociation Areas
The Specialized Language Areas in the BrainWernicke’sareaAnalytical area/plays a role in personalitySpeech center(Broca’sarea)Speech production/regulates breathing pattern for speechReceptive speech areaAdjusts the speech based on feedback from auditory stimuliHigher-Order Functions
Basal nucleiMasses of cerebral gray matter burieddeep in the white matterLateral to the thalamusThree brain centres form the basalnuclei and are collectively called thecorpus striatum:Caudate nucleusPutamenGlobus pallidusReceive input from the substantia nigra of the midbrain and the motor areasof the cortexInvolved in motor controlSends signals back and forth to midbrain and cortex
Limbic systemCentre of emotion and learningA limbic system in each hemisphere(bilateral)Consists of (at a minimum):Limbic lobeCingulate gyrusDentate gyrusParahippocampal gyrusHippocampus (memory functions)AmygdalaAlso: mammillary bodies, thalamicnuclei, parts of frontal lobe
ThefornixTract of white matter connecting the hippocampus with thehypothalamusMany fornix fibers extend to themammillary bodiesMammillary bodies control reflex movements associatedwith eatingOther nuclei in the thalamus and hypothalamusAnterior nucleusReticular formationLimbic system
Cranial Nerves
The Cranial NervesThere are 12 pairs of cranialnervesThese nerves innervate theperiphery emerging from thebrain (not the spinal cord)These nerves are on theventrolateral surface of thebrainThey are numbered beginningat the anterior aspect of thebrainThey are numbered N I to N XII
Function:Sensory (smell)Origin: Olfactory epitheliumForamen:Olfactory foramina within the cribriform plateDestination:Olfactory bulbsOlfactory nerves(I)enter bundles calledolfactory bulbsAxons proceed to destination viaolfactory tractsThe Olfactory Nerves (I)
Function:Sensory (vision)Origin:RetinaForamen:Optic canalDestination:Diencephalon,then to occipital lobeOptic nerves(II) from theretina cross (to a certaindegree) theoptic chiasmThe nerves continue totheir destination via theoptic tractsThe Optic Nerves (II)
Function: Controls extra-ocular eye muscles: superior, inferior, medial rectus,inferior oblique/levator palpebrae superioris/motorOrigin: MesencephalonForamen:Superior orbital fissureDestination:Extra-ocular eye musclesOculomotor nerves(III)haveautonomic fibers that synapsein theciliary ganglionThe Oculomotor Nerves (III)
Function: controls the superior oblique eye muscle/motorOrigin: mesencephalonForamen:superior orbital fissureDestination: superior oblique muscleTrochlear Nerves(IV)
FunctionMixed (sensory and motor) functionOphthalmic
