Uropi hwomunhu: mamiriro

Uropi hwomunhu anopa Kufambisa uye kudzora zvose pamuviri mashandiro kuti zvinokosha muupenyu kushanda, uye anodzora maitiro. Zvido, pfungwa, kunzwa - zvose zviri kwakabatana uropi. Kana muviri ichi haasi kushanda, munhu anova "chirimwa."

Uropi hwomunhu: characterization

Brain - symmetric yakarongeka, zvisinei, kufanana nezvimwe nhengo. uropi uremu pakuzvarwa anenge mazana matatu magiramu, vakura nayo anoyera rimwe nehafu makirogiramu. Tichitarisa mamiriro hwomunhu, tinogona pakarepo kuziva hemispheres mbiri dziri yakavigwa pasi pakadzika inotungamirwa. Hemispheric akafukidza chairwo convolutions, Kuwedzera chokunze medulla. Shure - the cerebellum, rezasi - hunde, izvo anoenda musana. Uye kubva hunde, uye kubva musana tsinga bazi panze, zviri kwaari mashoko kubva receptors kusvika uropi vakapedzwa, zviri kwavari uropi anotumira anonongedzera tsandanyama mumasero.

Mukati uropi ane chena fuma vanoumba tsinga fibers kuti batanidza zvikamu zvakasiyana muviri nokuita pakati pachavo tsinga kuripa dzimwe nhengo, uye pfumbu fuma Anoumba cerebral cortex uye rinoumbwa zvikurukuru tsinga masero miviri. Uropi hwomunhu runochengetedzwa Nemadehenya - mapfupa nyaya. Zvinhu zvinowanikwa mukati nhengo uye mapfupa namasvingo dzakaparadzaniswa anoshongwa matatu: yakasimba (rokunze), nyoro (mukati) uye nomucheka arachnoid. The zvichiguma nzvimbo pakati anoshongwa yakazara murwiyo akafanana yeplasma ropa, CSF (cerebrospinal) mvura. Yakabereka chaizvo mvura iri ventricles uropi - iri in mukati maro, basa rayo - kupa uropi hwomunhu hunokosha muviri.

The carotid arteries dzinopa cerebral riparadzirwe, vari akakamurwa nechepasi huru mapazi kuti kungapfuurira siyana kumatunhu uropi. Chakatishamisa uropi anoramba anogamuchira 20 muzana yeropa achiparadzira mumuviri, kunyange nhengo kurema zvachose kurema munhu wacho muzana 2.5 chete. Pamwe neropa kuuropi yaipiwa pamwe okisijeni, achivapa zvikuru, sezvo muviri pachake simba reserves yakaderera chaizvo.

Brain masero

Masero anonzi Tutsinga tunofambisa mashoko utwu, ndiwo musimboti tsinga. Ivo basa processing ruzivo. Uropi hwomunhu chine kubva 5 kusvika mabhiriyoni 20 Tutsinga tunofambisa mashoko utwu. Kunze kwavari, kuti nhengo kupa masero glial, riri pamusoro 10 nguva kupfuura Tutsinga tunofambisa mashoko utwu. masero Glial dzinoumba marangwanda tsinga rinenge muzadze nzvimbo pakati Tutsinga tunofambisa mashoko utwu. Kufanana nevamwe chero masero, Tutsinga tunofambisa mashoko utwu vari takapoteredzwa yeplasma membrane. Masero vawedzere pezvakaitwa - axons (kakawanda kupfuura rimwe chete muchitokisi axon urefu kubva vaviri masendimita kuti mamita anoverengeka) uye dendrites (neimwe dzouropi dendrites zhinji, ivo mapazi uye pfupi).

Uropi hwomunhu: madhipatimendi

Conventionally, uropi muzvikamu zvitatu: pamberi uropi, hunde, cerebellum. Hunoita nhengo nhatu rakakamurwa hemispheres maviri, thalamus (kutsinga dzinouya neerekitironi anogamuchira mashoko kubva mapazi uye kuparadzira nayo kutsinga dzinouya cortex) uye hypothalamus (nharaunda kudzora homeostatic basa), pituitary - kukosha shwanu. Hemisphere - kupfuura kuuropi interconnected corpus callosum - danda axons. Mumwe hemisphere ane occipital, parietal, zvenyama frontal lobes. The hunde zvinosanganisira kuti medulla oblongata (rezasi chikamu hunde, izvo zvinoenda musana), kuti pons (chokuita cerebellum etsinga fibers) uye midbrain (kuburikidza kune musana vari gwenya nzira). The cerebellum riri pasi occipital lobes ari hemispheres uropi, izvozvo anodzora nzvimbo hunde, maoko nemakumbo, musoro, anobatsira guru basa generating motokari unyanzvi.
