DTR is a monosynaptic reflex arc. Nws yog monosynaptic vim hais tias tsuas yog ob lub paj hlwb koom nrog: ib qho kev hnov lus thiab lub cev muaj zog neuron, nrog rau tib lub synapse. Tom qab tus kws kuaj xyuas kais cov leeg nqaij, cov nqaij fibers 'stretch yog kuaj pom ntawm cov leeg spindle nyob hauv cov leeg nqaij.
Yuav ua li cas hom reflex yog leeg pob txha?
Tendon reflexes yog single synapse reflexes. Kev nrawm nrawm ntawm cov nqaij ntshiv cov leeg spindles thiab cov lus no yog xa los ntawm cov hauv paus kev hnov qab mus rau tus txha caj qaum ntawm qib segmental ntawm cov leeg nqaij stimulated.
Puas Deep tendon reflexes normal?
Los ntawm lub rooj sib tham qhov sib sib zog nqus tendon reflexes tau muab qhab nia raws li hauv qab no: 0=tsis teb; ib txwm txawv txav. 1+=me ntsis tab sis qhov tseeb tam sim no teb; tej zaum yuav los tsis zoo li qub. 2+=ib tug brisk teb; normal.
Puas tag nrho cov tendons muaj reflexes?
"Tendons muaj me ntsis ua nrog cov lus teb, tsis yog lub luag haujlwm rau kev xa cov tshuab xa mus sai sai los ntawm lub zog rauj rau cov leeg leeg. Tsis tas li ntawd, qee cov leeg nrog stretch reflexes tsis muaj tendons (piv txwv li, "lub puab tsaig jerk" ntawm cov leeg nqaij)".
Dab tsi sib sib zog nqus tendon reflexes qhia?
DTR ntawm sab qaum teb tuaj yeem muab qhia txog qib kev raug mob ntawm tus txha caj qaum. Kev nce reflexes tuaj yeem yog qhov qub, tshwj xeeb tshaj yog tias ob sab. Cov me nyuam feem ntau muaj exaggerated reflexes(ntau tshaj nyob rau sab qaum teb). Txhim kho reflexes tuaj yeem cuam tshuam nrog lub cev muaj zog neuron lesion.
