QUESTION
flexorl (withdrawal)l reflexl example
Answer:
-quickl contractionl ofl flexorl musclesl resultingl inl thel withdrawall ofl al limbl froml anl
injuriousl stimulus
-Youl stepl onl al brokenl bottle
-Evenl beforel youl arel consciouslyl awarel ofl thel pain,l youl quicklyl pulll yourl footl awayl
beforel thel glassl penetratesl anyl deeper
-actionl involvesl contractionl ofl thel flexorsl andl relaxationl ofl thel extensorsl inl thatl limb
QUESTION
polysnapticl crossedl flexor-extensorl reflex
Answer:
-Ifl youl werel tol stepl onl Legol piecel withl yourl rightl foot,l thel painl emanatingl froml yourl
rightl footl willl ultimatelyl causel youl tol flexl yourl legl andl pulll yourl footl backl orl
"withdraw"l froml thel Legol piece
-However,l becausel you'vel withdrawnl yourl rightl foot,l youl arel nowl onlyl standingl onl
onel leg
-Justl asl you'rel aboutl tol falll over,l yourl leftl legl tensesl upl andl stabilizesl you,l sol youl
remainl upright
,QUESTION
extensorl (tendon)l reflexl example
Answer:
-inl responsel tol excessivel tensionl onl thel tendon
-Inhibitsl musclel froml contractingl strongly
-Moderatesl musclel contractionl beforel itl tearsl al tendonl orl pullsl itl loosel froml thel
musclel orl bone
-Althoughl thel tendonl reflexl isl lessl sensitivel thanl thel stretchl reflex,l itl canl overridel thel
stretchl reflexl whenl tensionl isl great,l makingl youl dropl al veryl heavyl weight
QUESTION
vestibulospinall reflex
Answer:
-passesl downl thel anteriorl funiculusl andl facilitatesl neuronsl thatl controll extensorl musclesl
ofl thel limbs,l thusl inducingl thel limbsl tol stiffenl andl straighten
-importantl reflexl inl respondingl tol bodyl tiltl andl keepingl one'sl balance
QUESTION
stretchl reflex
Answer:
-ifl yourl headl startsl tol tipl forward,l itl stretchesl musclesl atl thel backl ofl yourl neck
-Thisl stimulatesl theirl musclel spindles,l whichl sendl signalsl tol thel cerebelluml throughl thel
brainstem
-Thel cerebelluml integratesl thisl informationl andl relaysl itl tol thel cerebrall cortex,l andl thel
cortexl sendsl signalsl back,l vial thel brainstem,l tol thel muscles
, -Thel musclesl contractl andl raisel yourl head.
QUESTION
Cerebelluml function
Answer:
-Smoothsl andl coordinatesl contractionsl ofl skeletall muscles
-Regulatesl posturel andl balance
-Mayl havel rolel inl cognitionl andl languagel processing.
