active n passive ? macm mane sebenarnya soklan tuh?? @ dah jumpa jwpan?? kongsi2 lah ~
stakat yg difahami : active ni kite buat sendiri , contoh active contraction , kite contract muscle guna tenaga kita, mcm buku.. kan muscle contract..*xtau btl2 @ silap.. markah mid year pun x tinggi sngt mcm org bertnya.. confused

salam,kalau ikut pendapat aku la..

active contracting tu mcm afnan ckp tu. kita bt sendiri. contoh er,kita bt flexion kat forearm kita. tanpa ada org lain yg tlg contractkan muscle kita. maksud er active lah contraction tu. kalau passive contraction,mcm ala ala physiotherapy tu kott? doctor tlg gerak2kan tgn patient.. ehehh..

tapi kalau passive stretch lak,contoh er kita bt experiment kat isolated muscle. kita stretch kan muscle tu. tak kira ah stretch kan muscle ke muscle spindle ke en. mcm kita stretch kan getah... huhue

and kalau wujud active stretch,mungkin maksud er macam muscle spindle yg mmg continuously stretched dlm bdn kita secara physiologynya.. maksud er muscle spindle kita tak stretched disebabkan ada org tlg stretchkan.. haha confused ke weh ayat ni?? Question

okehh...kepada yg faham,tolong betulkan pendapat saya nehh.. kalau tak faham harap maaf lah.. heeee Embarassed

dia sebenarnya gini, kite blajar nih pasal reflex arc ( afferent, efferent, centre ) yg melibatkan voluntary muscle, spt biceps/ triceps n dll.. @ nk bgtau cmne? stakat ak paham bleh j nk tlg xplain ~

siapa ingat,doktor akif ada bg contoh.
sorang makcik ni sakit telinga kot.
then gi rawat,doktor letak cecair yg suhu dia x sama dgn suhu bdn.
then makcik tu tumbang..sbb rasa imbalance. Shocked

huhhue.. betol ke pjalanan kisah ni..(?)

cer citer balik pasal ni..n explain skit pe benda yg dokt nk ckp senanya?? Rolling Eyes

Substantia Gelatinosa of Rolandi (SGR) ni hanya lamina II dan III sahaja ke (buku teks sensory mukasurat 58) atau seluruh posterior horn cell (buku Experimental Physiology Dr Sherif Tawfik mukasurat 7) atau hanya lamina II (http://en.wikipedia.org/wiki/Substantia_gelatinosa_of_Rolando)???

Mohon pencerahan sunny sunny sunny .

Benda important dalam ni:

Reflex (semua jenis, terutamanya stretch reflex sekali dengan komponennya)
Basal ganglia
Cerebellum
Vestibular & Equilibrium (kena faham cara nak "balance" badan kita guna vestibular apparatus dalam inner ear)

Ada lagi, orang lain boleh tambah kot.

tmpg tanyer...

bab motor sal UMNL & LMNL p/g 46..

specific bab UMNL :point no 2 : hypertonia..

klu phm hypertonia terjadi oleh sbb facilitatory RF and vestibular nuclei become hyperactive..tapi kenapa aayat sblm nyer cakap, facilitatory centers lower down..

ape maksud facilitatory centres lower down???

ni citer pasal ACTIVE contraction & passive stretch ke citer pasal equilibrium???

motor nervous system  1269259657_omg_cat

i think la...

Active contraction of a muscle is a muscle that we contract by ourselves, by our control voluntarily. Simultaneously, the antagonist muscle will be passively stretching.

E.g.: We contract our biceps actively by our power voluntarily. Simultaneously, the triceps is passively stretching. Consequently, thee stretch reflex occurs as negative feedback, and the biceps relax while the triceps contract to maintain the length of the muscle.

To Naqiyan Anis, pasal imbalance from that makcik. Are u asking for the equilibrium? About that, as we knew, one of the methods of stimulation of semicircular canals is heat convection. The doctor was putting a hot water around 43 degree C. Of course xsma dgn suhu bdn (around 37 degree C). Stimulation of the semicircular canals would increase the impulses of the ear the doctor put the hot water (only semicircular canals of one ear could be stimulated through this method). Supposedly, the impulses would be sent to the higher centers through vestibular nerve to vestibular nucleus then through vestibulospinal tract, the muscles of the lower limb react to maintain balance of the body. However, the makcik's vestibular nerve has a problem i think. Maybe, there's a disease affecting the vestibular nerve or vestibular nucleus or the pathway of vestibulospinal tract which important in response of the muscles of the lower limb to maintain balance.

Disease maybe labyrinthitis (inflammation of the semicrcular canals) or vestibular neuritis (rsenyer la).

That's all. If there's something wrong, correct me, then.
Thx.

ad org claim mksud 'lower down' tu mksudnyer adlh 'di bwhnyer' -cri kt google translate
mksudnyer dye nk ckp yg position dye kt bawah, bukn mksud 'merendahkn'

rasanya ak pun berpendapat lebih kurg sama j, sebab hypertonia memg stakat yg difahami disebabkan increased facilatory stimulus..mybe lower down tu mksudnya lain2 selain " lower the stimulatory impulse "
mklumlah BI dulu jarang2 j dpt A..

that's RIGHT, ayunishafaf!!!

"lower down" in the book means the facilitatory reticular formation and vestibular nuclei below the level of internal capsule which is damaged in UMNL.

primary motor area 4 is also one of supraspinal facilitatory centers, however, it is not affected (not become hyperactive as RF and vestibular nuclei) because the pyramidal tract is interrupted due to damage of internal capsule posterior limb.

look again at the sentence:

"The facilitatory centers lower down i.e. facilitatory reticular formation and vestibular nuclei become hyperactive, blablabla..........."

hypertonia occurs because of loss of inhibitory effect of muscle tone, so, the facilitatory effect becomes the upper hand (hyperactive).

drpetemd : yer2 ,aku tersilap ayat kat citu..xmenggunakan ayat2 buku..btllah tu decreased/loss inhibitory effect..
bukan stakat BI, BM pun aku kurang jgak..xtgk lagi arab
