Cov kua dej puv sab hauv pob ntseg transduces suab vibrations rau hauv neural signals xa mus rau lub hlwb rau kev ua. Cochlea yog lub cev loj ntawm lub cev hnov hauv sab hauv pob ntseg . Cov plaub hau hauv cochlea ua cov kev hloov ntawm lub suab nthwv dej.
Ib yam li ntawd, nws raug nug, hom receptors twg siv rau kev hnov lus?
Sensors receptors ua ntau txoj haujlwm hauv peb lub cev. Thaum lub zeem muag, tus pas nrig thiab lub khob hliav qab photoreceptors teb rau teeb siv thiab xim. Thaum lub rooj sib hais, cov kws kho tsheb nyob rau hauv cov plaub hau ntawm pob ntseg nrhiav kev co ua los ntawm pob ntseg.

Yuav ua li cas lub hnov rhiab receptor nkoos lub sensory neuron?
Piav li cas a hnov rhiab receptor nkoos ib tug sensory neuron . Lub cell tso ib tug neurotransmitter uas txhawb nqa nyob ze kev xav cov paj hlwb, thiab lawv xa cov kev xav mus rau ntawm cov ceg cochlear ntawm vestibulocochlear cov hlab ntsha mus rau lub pob ntseg pob ntseg ntawm lub lobe sab hauv ntawm lub hlwb.
