Trochlear Nerve hi eng nge ni?

A awlsam zawngin sawi ila, trochlear nerve hi kan thluak atanga kan mit thlenga thuchah thawn chhuaktu cable te tak te ang a ni. Kan lu chhungah hian nerve group 12 a awm tih i hria em, chu chu cranial nerve kan ti a ni? Trochlear nerve hi chu sawm leh pahnih zinga palina a ni (Cranial Nerve 4 emaw CN IV emaw an ti bawk).

Kan taksa chhunga nerve thenkhatte hian khawih leh temperature (sensory) ang chi thilte hriat theihna turin min pui a, thenkhat chuan chetna thunun turin min pui bawk. Mahse, he trochlear nerve hnathawh ber chu kan mit che vel control hi a ni. Chu chu motor nerve, a nih loh leh kinesthetic nerve a ni tihna a ni. Heng trochlear nerve pahnih hi kan nei a, mit pakhat tan pakhat kan nei a.

He nerve hian eng nge a tih tak tak?

Okay, tunah chuan he nerve te tak te hian eng nge a tih tak tak tih hi han en ila. Trochlear nerve hian hna lian ber pakhat a nei a. Tin, chu chu kan mit chhunga taksa peng bik, superior oblique muscle hnena thuchah thawn a, chu chu a kal tir a ni.

He trochlear nerve hi, chu ``superior oblique muscle'' ka sawi tawh nen chuan, an inzawm khawm chuan heng thilte hi kan ti thei a ni:

• Hnung lam hawi rawh: Hêng pahnih hian i mit chu hnuai lam hawiin an hruai a, chu chu lehkhabu i chhiar lai emaw, stairs i chhuk lai emaw a ni.
