cerebellum-physiology

Question 1

Archi cerebellum

Answer 1

Archi Cerebellum (vestibular) Flucco nodular LobeFunction: Coordinate eye movement with Head. (MLB)++3,64 Cranial N.Nadjust body positionSite, Predict site For next move, Adjust action of agonist, antagonist.Control axial, proximal Ms.Lesion1) Drunken gait(2) Nystagmus

Question 2

Paleo cerebellum

Answer 2

pale cerebellum (spinocerebellum)Vermal +2 para vermal parts Fastigial GE nucleiCo ordination of voluntary Movement1)Servo Comparator Braking.Control axial, proximalStop A Extra A after stoping of Movement by Sending braking inputs.- detect errors of performed movement Send it to Cortex2- Dampingsmooth the move ment +agonist -antagonist.3- Rapid ballistic movement”Circus clown”Effect of spinocerebellum on Ms tone: inhibitory.Lesion.1- intentional Tremors.2- Dysmetria3- under lover shooting

Question 3

Neo cerebellum

Answer 3

3) Neo cerebellum ( cerebrocerebellum) Dentate N. (Lateral).Function:1-Planning and programing of movement with: BG2 extra motor predictive function.Inputs. →→→Expect time of events as: goal keeper.3- timing Predicting+Timing Sensory input→Control rate, time direction of movement→reach goal in certain time Effect on Ms Tone:StimulatoryNet Result of cerebellum on SR: ++ stimulatory.
