Motor control 1 Flashcards
what type of fibers convey vountary motor contorl
a motorneurons
what type of nucli contorl spinal reflexes
brain stem nuclie
what is the somatoptic map of the spinal cord
dicates that the cenrtl part of th grey mater does central psotuarl muscles such as those of trunk, and lateral part has more to do with a arms
in which side of the spianl cord is the motor neurons cell bodies higher
the right sidde
wher does the spinal cord get its information from
brain stem and cortial and corticospinal pyrmidal tract
function of spinal cord
proprioceptions, touch, pain
functions brainstem
vestibualr systems about balance
cortex
in response to viusla opathalcor , emion and intellect
what is the strech reflex
when the tneond stenes it cuase a reflex of extension
what happens in the strech reflex
caues contraciotn of agonist muscle
antagonist mucle relaxes
a signsla is senses to thalamus and somatosensory cortex
what is reciprolca inhitborion
a alpha motor nutaorn blockes the antagonsi musles making it relgax
does the strech recept go rhough greay or white mater
grey mater
does the strech synpaes and hwer
in dorsal route ganglion and greya mater where after spiting it synapes for anatagos and agiaon for agonist
how does the strech replex fefect aciton poteosn
increase action poteinl of 1a
why is it called a monosymphaic reflex fo the stretch frelex
as it only has one true synapase
what is the fucniton of the golgi tendon rogans
when the nerve ending are commpresed it cause 1b fibers to increase citon potenila dn cause sinverse stretch reflex
what happesn in inverse strech relex
inhibtors agonist musles
exites antagmoism mules
spinal doresla columbs is used to pass information to somatosensory corte
what is the clasp knife relex
where the inverse strech relex cuase the joint to become fully extended
how many synapes are there in the golig tenon organ
2 - both insdie the grey mater of the spianl cord
what cuaes hte flexor/ withdral relex
pain in the skin
how doe sht eflexor reflex work
increased activy of the fleozr musles
antagonistic extenosr are inhibited
also exitiery interos cross he spinal cord to excite cotnralator extenosr
spinal nruons corss spianl cord to inhibri contorlator fleuxs to help balance
sensory inomarl go up to the brain via the cotraltalr spinoplaic tract
what tract is seud for flexor and withdrawal relex
controlatalr spinal tract
what type of neruon is in the flexor / withdral relex
a delta
why are nocieptise fibers slower than musles sinlde fibers
as theey are smaller
how to overrised inverse strech flrex
using cns, aplpha mototr nutos over ride ibibtion from gts to ain’t musles contraction, this is done by them blocking the axon due to the hyperolisaiton of a motonurions
how to stop the strech relex being overwriddedn
jendrassick maover - whre ouo cross arms, and interlock fingers and pull hard, while clenching teeth
what do you have to do to overcome relex
anticipate it
