Ib tug muab stretch rov ua dua koom nrog cov synapsebetween sensory (cov leeg leeg spindle receptors) thiab lub cev muaj zog neurons atonly ib qib ntawm tus txha nqaj qaum thiab lub hlwb tsis koom nrog. Cervical theem kev puas tsuaj txawm li cas los, yuav tsis disrupt lub hauv caug - jerk reflex uas yuav tsum tau tsuas yog qhov qis sacral cheeb tsam ntawm lub tus txha nqaj qaum beintact.
Ib yam nkaus, dab tsi yog cov kauj ruam ntawm reflex arc? Cov ntsiab lus hauv txheej no (5)
- stimulus activates tus receptor.
- lub paj hlwb ua rau taug kev los ntawm lub paj hlwb hnov mus rau theCNS.
- interneurons koom ua ke thiab txheej txheem cov ntaub ntawv.
- lub cev muaj zog neuron xa cov hlab ntsha mus rau ib qho kev cuam tshuam.
- tus neeg ua haujlwm teb rau qhov kev xav ntawm lub paj hlwb.
Yog li ntawd, dab tsi yog 5 yam ntawm lub reflex arc?
Reflex Arc Cheebtsam . Feem ntau reflex arcs muaj tsib lub ntsiab cov khoom : receptors, sensoryneurons, interneurons, lub cev muaj zog neurons thiab cov leeg.
Dab tsi yog qhov reflex arc hauv lub paj hlwb?
A reflex arc yog ib txoj hauv kev neural uas tswj tau a rov ua dua . Hauv cov vertebrates, feem ntau cov paj hlwb tsis nkag ncaj qha mus rau hauv lub hlwb, tab sis sib txuas hauv tus txha caj qaum. Ua tau zoo paj hlwb fibers nqa lub cev muaj zog paj hlwb cov cim qhia los ntawm lub hauv siab qis dua rau cov leeg.
