The mutum kwakwalwa sifa da aiki

Human kwakwalwa sifa da aiki da aka tattauna a wannan talifin da ake located a cikin kwanyar da kuma kunshi biyar sassan, ciki har da midbrain, tsaka-tsaki, na baya, da kuma wani elongated gaban. A talakawan adult kwakwalwa Tã yi game da 1.5 kg, kuma a jarirai kusan 400 grams.

The mutum kwakwalwa, tsarin da kuma ayyuka na wanda aka ƙaddara da damar da kwayoyin, wanda qunshi tsakiyar, bãyansu, elongated kuma matsakaici rarrabuwa. Su na bayar da muhimmanci da kuma cerebral hemispheres, wanda ya bambanta mutum daga dabbobi. Daga daban-daban sassan zo jijiyoyi da cewa gama kwakwalwa to duk gabobin da mutum rabe. Da taimakon jijiya endings kwakwalwa na nazarin da kuma matakai da waje tsoma da kuma samuwar kasashe, da kuma ma ya haifar da zama dole mayar da martani ga su. The mutum kwakwalwa, tsarin ta sassa da kuma ayyuka aiki a hanyar da cewa mafi yadda ya kamata daidaita da muhalli da yanayi. By wannan tsari, akwai aiwatar da daidaituwa na ayyuka dukkan gabobin da kyallen takarda na jiki, dangane da daban-daban dalilai.

Medulla oblongata ne mai ci gaba da laka. Yana daukawa da reflex madugu da kuma aiki. Waje, an rufe tare da wani farin abu cewa Forms conductive hanya ga kwakwalwa. Its tsakiyar ɓangare kunshi m al'amarin, wanda shi ne rukuni na neurons alhakin parasympathetic juyayi tsarin. Medulla ƙunshi cibiyar na cardiac aiki, na numfashi da kuma vasomotor cibiyoyin. Ya kuma ne ke da alhakin unconditioned alimentary reflexes kuma m reflexes.

Na baya, tsarin da kuma ayyuka na wanda samar da wani reflex aiki, kunshi da cerebellar pontine da medullary gada. Sama da medulla oblongata yana cerebral gada, wanda ya ƙunshi tsakiyar fuska da kuma oculomotor jijiya endings. Har ila yau wuce ta cikin hasken dake fitowa daga medulla oblongata zuwa babba sassa na kwakwalwa. Yana kula da motsi na jikin mutum, kazalika da tallafa wa da ma'auni na cerebellum. Ya kunshi biyu hemispheres da kuma tsakiyar ɓangare, kuma an rufe shi da launin toka al'amarin. A mafi yawan aiki ci gaban da cerebellum ya auku tsakanin 5 da 11 watanni na rayuwa.

Tsari da kuma aiki na midbrain samar da wani mutum da cikakken aiki auditory da na gani bayanai. Wannan bangare na kwakwalwa da aka hada da ƙafãfu biyu cewa connect da shi zuwa ga matsakaici da kuma medulla, kazalika da rufi, inda cikin cibiyoyin na gani, kuma auditory samuwar kasashe.

Intermediate mutum kwakwalwa kunshi da thalamus, epithalamus, geniculate jikinsu da kuma podbugornoy yankin (hypothalamus). Shi ne ke da alhakin aiki na tsakiyar juyayi tsarin mutum. Thalamus kula ji na ƙwarai, fuska, gestures da kuma sauran mutum motsin zuciyarmu. A hypothalamus ne ke da alhakin autonomic juyayi tsarin da kuma damar da metabolism, endocrine aiki, da kuma aikata aikin da daidaituwa na barci. Geniculate gawarwakin dauke da na gani, kuma auditory cibiyoyin.

A forebrain mutum, tsarin da kuma ayyuka na wanda ake nufin management na dukan jiki, da aka yi sama da cerebral hemispheres, wanda suna da alaka da ayyukan marubuta callosum. A cerebral bawo rufe musamman m al'amarin. Godiya ga shi, bayar da tafarkin da ga sakonni daga jijiya endings. Haushi forebrain qunshi 6 yadudduka na daban-daban jijiya endings da GROOVES ne zuwa kashi 4 aikin sassa: frontal lobe, parietal, na boko da kuma occipital. A mafi m ne frontal lobe, wanda aka rabu da tsakiyar sulcus na parietal lobe. A cikin frontal lobe asusun for game da 50 bisa dari na jimlar kwakwalwa taro. Haushi shi ne tushen mutum shafi tunanin mutum da matsayi. A dama da hagu yammancin duniya ne dan kadan daban-daban, tare da sakamakon cewa hagu yammancin duniya ne ke da alhakin m tunani da dama - ga m.
