Reflex arcs Sensory neuron xa hluav taws xob impulses mus rau lub relay neuron, uas nyob rau hauv qaum qaum ntawm CNS.
qhov hnov tsw thiab relay neurons ntsib nyob rau hauv qhov kev txiav txim siab?
Sensory neurone xa hluav taws xob impulses rau relay neurone, uas nyob rau hauv qaum qaum. Lawv txuas neurones sensory rau lub cev muaj zog neurones.
Qhov twg tuaj yeem pom cov neurons pom?
Relay neurons muaj nyob nruab nrab ntawm kev nkag siab lub tswv yim thiab lub cev muaj zog tso tawm / teb. Relay neurons muaj nyob hauv lub hlwb thiab qaum qaumthiab tso cai rau kev hnov lus thiab lub cev muaj zog neurons sib txuas lus. Lub cev muaj zog neurons muaj nyob rau hauv lub hauv paus paj hlwb (CNS) thiab tswj cov leeg nqaij.
Dab tsi yog qhov sib lawv liag ntawm cov neurons hauv lub reflex arc?
Yog li lub reflex arc muaj tsib kauj ruam hauv kev txiav txim- sensor, sensory neuron, tswj chaw, lub cev muaj zog neuron, thiab nqaij.
Relay neuron yog dab tsi?
Ib relay neuron (tseem hu ua interneuron) tso cai rau kev hnov lus thiab lub cev muaj zog neurons sib txuas lus nrog ib leeg. Relay neurons txuas ntau yam neurons hauv lub hlwb thiab qaum qaum, thiab yooj yim rau kev paub, vim lawv luv axons.
