A surface na cerebral hemispheres aka kafa ta abin? Brain Structure

Kwakwalwa na located in girman kogo. Ya kunshi biyar sassan: medulla oblongata, bãyansu, tsaka-tsaki, matsakaici, da kuma karshe, kuma ake magana a kai a matsayin cerebral hemispheres.

M ventral surface (medulla, kazalika da sauran sassa) yayi dace da ciki concave rabo daga kwanyar. A daya hannun, da ƙananan surface zama tushe na kwakwalwa, yana da wani hadadden tsarin, wanda yayi dace da girman kwanyar rami a wannan wuri.

Bari mu bincika a cikin daki-daki, abin da surface na cerebral hemispheres kafa.

endbrain

A karshen kwakwalwa kunshi biyu hemispheres, rabu da wani a tsaye Ramin. A cikin zurfin suka gama da ayyukan marubuta callosum da zangarniya. A abun da ke ciki na kwakwalwa ya hada da hagu da kuma dama kaikaice ventricles, abin da suke a daya da kuma sauran yammancin duniya. A waje surface na cerebral hemispheres kafa ɓawon burodi, da aka sani da "alkyabbar". Mayafin ne fari da kuma zurfin m al'amarin. Iyakar tsakanin tsaka-tsaki da kuma telencephalon located inda ciki kwantena dab a kaikaice gefen thalamus.

yammancin duniya

A haushi daga abin da cerebral hemispheres surface aka kafa, na bakin ciki farantin na launin toka. Hemisphere kunshi wadannan aka gyara:

• superolateral - convex.
• Tsakiya - jirgin sama.
• kasa - da wuya ƙasa.

Kowace daga cikin dubawa tsakanin ta gefuna:

• saman.
• ƙananan kaikaice.
• ƙananan tsakiya.

Protruding sassan ake kira:

• frontal iyakacin duniya.
• occipital iyakacin duniya.
• da na boko iyakacin duniya.

A surface na cerebral hemispheres na kwakwalwa yana da wani hadadden tsarin, da yawa fissures da convolutions na daban-daban masu girma dabam, siffofi da kuma kwatance.

A frontal lobes superolateral surface

A gaban kwakwalwa located da frontal lobes, da frontal iyakacin duniya da kuma kawo karshen m zuwa a kaikaice tsagi da kasa na tsakiyar tsagi baya. Karshe ne frontal jirgin sama, ya fara daga da tsakiya surface da kuma lazimta a kansu da babba baki, shi gudanar saukar ba tare da kai a kaikaice GROOVES.

karshen lobe

Wannan bangare ne bayan parietooccipital furrows, inda ya ci gaba da superolateral surface na cerebral yammancin duniya. Sauran rabo ne karami a kwatanta da wannan. Yana yana da wani sosai bambancin da gyri na occipital iyakacin duniya da kuma iyakar.

parietal lobe

A baya gefen tsakiyar tsagi ayi parietal lobe. A daya hannun iyaka abubuwa parieto-occipital kwarin kunya, wanda an zubar a da tsakiya surface. Yana yanke ta cikin kwakwalwa a saman da kuma motsa zuwa superolateral surface.

boko lobe

Wannan bangare ne located a kan ƙananan sassa na gyaffan hemispheres. A daya hannun shi da aka raba frontal da kuma a kan sauran - parietal lobes by zurfi a kaikaice GROOVES. Ƙasa, wanda yake rufe raba wani tsibirin, da ake kira da boko hula. A saman boko lobe ne na boko iyakacin duniya. Side biyu furrows tsaya a waje, wanda kusan su a layi daya zuwa a kaikaice. Tarar da kwakwalwarmu ne wajen tare da GROOVES.

Islet surface superolateral

Wannan sulusi da murabba'i ne located a cikin kaikaice sulcus. Yana zama m, idan ka cire sassa na parietal, frontal da kuma na boko lobes, ko tura su. Its madauwari tsagi an rabu duk sauran hannun jari. A surface na tsibirin yana da wani daban-daban tsawon gyrus. Tsakanin abin da yake a bãyansu, kuma located a kasa da kuma aka located a gaban tsakiya sulcus na tsibirin. Kuma akwai wani karamin sashi na nizhneperedney thickening ba tare da furrows, wanda ake kira bakin kofa daga cikin tsibirin.

Da tsakiya surface

Da tsakiya surface na kwakwalwa ta ƙunshi dukan hannun jari, fãce tsibirin. A kan ayyukan marubuta callosum ne kwarin kunya. An directed gaba da sauka. An located a saman da bel da tsagi, wanda fãra daga baki na tarin rubuce-rubuce callosum, shi ke sama, sa'an nan ya jũya bãya, layi daya zuwa tsagi. Ya ƙare har a cikin wani nau'i na nadi podtemennoy kwarin kunya. A nan, daga kugu gefen tsagi rassan directed sama.

Tsakanin bel da GROOVES na tarin rubuce-rubuce callosum ne cingulate gyrus. A daya hannun shi Narrows, samar da Isthmus cingulate, wanda ke shiga cikin mafi fadi gyrus. Tarar da kwakwalwarmu tare da Isthmus kira arched. A ta zurfafa akwai wani bakin ciki m farantin, raba da kananan furrows. Wannan ne dentate gyrus. Ta tsakiya surface na kwakwalwa, wanda aka shirya tsakanin babba baki na yammancin duniya da kuma bel tsagi, yana nufin da frontal da parietal lobes.

Da tsakiya surface daga cikin manya frontal gyrus positioned gaba dangi da sama baki daga cikin tsakiyar sulcus. Tsakanin gaba da raya gefuna da runs precuneus, wanda yana nufin parietal lobe.

A wani m kwana, ajar baya ne parietal-occipital sulcus da calcarine. Karshe ya samo asali a tsakiya surface na occipital iyakacin duniya da kuma motsa gaba da cingulate gyrus. Wannan shafin ne a cikin nau'i na alwatika aka kira wani sandan. Calcarine sulcus, wanda ya takaita lingual gyrus, tsaye a waje da kyau. Kasa da karshen ne na biyu sulcus.

A kasa surface

A surface na cerebral hemispheres aka kafa a cikin ƙananan sashi ba shi da quite wuya. Its agara kunshi cikin frontal lobe. Yana tsaye bayan da na boko iyakacin duniya. Domin wannan surface ne m ɓangare na occipital da kuma na boko lobes.
Kasa frontal lobe a wannan matakin tare tsaye tsaguwa ne olfactory tsagi a gindi daga wanda karya kwan fitila da kuma olfactory fili, da motsi a cikin wani alwatika. Yana kasaftawa da kuma a kaikaice olfactory tsiri. A wani bangare na frontal lobe tsakanin olfactory tsagi, kuma a tsaye Ramin aka kira a mike gyrus. Rabo gefe na tsagi da aka raba olfactory orbital GROOVES a kan orbital gyrus na daban-daban siffofi da kuma masu girma dabam.

Lower raya surface na kwakwalwa dabam na biyu tsagi located a kaikaice to kuma a kasa da lingual gyrus a cikin boko, kuma occipital lobes. A kadan kara gaba na karshen da tabbaci sulcus ne hanci furrows, tsare da parahippocampal gyrus. Da tsakiya occipital-boko gyrus aka located 'yan kaikaice na biyu. Tsakanin shi da m kaikaice occipital-boko gyrus yana occipital-boko sulcus. Amma a nan ne m-kaikaice iyakoki baki yammancin duniya.

A limbic tsarin

Ya kamata in ce 'yan kalmomi game da wadanda yankunan, wanda su ne yafi a kan da tsakiya surface da kuma kafa ta motsin zuciyarmu, motivational hali, barci da kuma sauran abubuwa. Suna da ake kira da limbic tsarin. A halayen aka halitta ta asali olfactory aiki. Saboda su su ne tushen morphological yankunan da ta fito daga cikin ƙananan-kaikaice sassan na kwakwalwa kumfa, da ake kira olfactory kwakwalwa.

A limbic tsarin kunshi da olfactory takardunsu kwararan fitila, alwatika, a gaban perforated abu ba a kan ƙananan surface na frontal lobe, da sauran yayan. A hada da wadannan yankunan ya yiwu ne da irin wannan tsarin, na yi wa juna dangantakar da kama da yawa halayen.
