Lidsk\u00e9 t\u011blo je jednou z nejslo\u017eit\u011bj\u0161\u00edch struktur, kter\u00e9 kdy v\u011bda zkoumala.

D\u00e1le objev\u00edte \u00fa\u017easn\u00e1 fakta o sv\u00e9m vlastn\u00edm t\u011ble.<\/p>\n\n\n\n

1. R\u00e1no jste vy\u0161\u0161\u00ed.<\/h2>\n\n\n\n

Kdy\u017e se probud\u00edme, jsme o n\u011bco vy\u0161\u0161\u00ed ne\u017e kdy\u017e jdeme sp\u00e1t. D\u011bje se to proto, \u017ee b\u011bhem sp\u00e1nku se p\u00e1te\u0159 uvol\u0148uje kv\u016fli absenci st\u00e1l\u00e9ho gravita\u010dn\u00edho tlaku. B\u011bhem dne t\u011blesn\u00e1 hmotnost op\u011bt stla\u010duje meziobratlov\u00e9 plot\u00e9nky, \u010d\u00edm\u017e se na\u0161e v\u00fd\u0161ka sni\u017euje o n\u011bkolik milimetr\u016f.<\/p>\n\n\n\n

2. Va\u0161e t\u011blo produkuje elekt\u0159inu<\/h2>\n\n\n\n

Nervov\u00fd syst\u00e9m funguje prost\u0159ednictv\u00edm elektrick\u00fdch impuls\u016f. Ka\u017ed\u00e1 my\u0161lenka, pohyb nebo reakce z\u00e1vis\u00ed na elektrick\u00fdch sign\u00e1lech vys\u00edlan\u00fdch mozkem prost\u0159ednictv\u00edm neuron\u016f. Tyto impulsy jsou extr\u00e9mn\u011b rychl\u00e9 a umo\u017e\u0148uj\u00ed t\u011blu reagovat na podn\u011bty t\u00e9m\u011b\u0159 okam\u017eit\u011b.<\/p>\n\n\n\n

3. V\u00e1\u0161 nos si dok\u00e1\u017ee zapamatovat tis\u00edce v\u016fn\u00ed.<\/h2>\n\n\n\n

\u010cich je hluboce spjat s pam\u011bt\u00ed. Mozek dok\u00e1\u017ee ukl\u00e1dat a rozpozn\u00e1vat tis\u00edce r\u016fzn\u00fdch v\u016fn\u00ed. Proto n\u011bkter\u00e9 v\u016fn\u011b tak intenzivn\u011b a okam\u017eit\u011b evokuj\u00ed star\u00e9 vzpom\u00ednky.<\/p>\n\n\n\n

4. Jejich kosti jsou extr\u00e9mn\u011b siln\u00e9.<\/h2>\n\n\n\n

I kdy\u017e se lidsk\u00e9 kosti mohou zd\u00e1t k\u0159ehk\u00e9, jsou velmi pevn\u00e9. V pom\u011bru k jejich hmotnosti mohou b\u00fdt pevn\u011bj\u0161\u00ed ne\u017e ocel. Nav\u00edc se neust\u00e1le obnovuj\u00ed a v pr\u016fb\u011bhu \u010dasu nahrazuj\u00ed star\u00e9 bu\u0148ky nov\u00fdmi.<\/p>\n\n\n\n

5. M\u00e1te v\u00edce ne\u017e 600 sval\u016f<\/h2>\n\n\n\n

Aby bylo mo\u017en\u00e9 prov\u00e9st jak\u00fdkoli pohyb \u2013 od \u00fasm\u011bvu po b\u011bh \u2013 svaly spolupracuj\u00ed. Mnoh\u00e9 z nich funguj\u00ed automaticky, nap\u0159\u00edklad ty, kter\u00e9 ovl\u00e1daj\u00ed d\u00fdch\u00e1n\u00ed a srde\u010dn\u00ed frekvenci. I b\u011bhem sp\u00e1nku z\u016fst\u00e1v\u00e1 t\u011blo aktivn\u00ed.<\/p>\n\n\n\n

6. K\u016f\u017ee je nejv\u011bt\u0161\u00edm org\u00e1nem v t\u011ble.<\/h2>\n\n\n\n

K\u016f\u017ee je pova\u017eov\u00e1na za nejv\u011bt\u0161\u00ed lidsk\u00fd org\u00e1n. Chr\u00e1n\u00ed p\u0159ed vn\u011bj\u0161\u00edmi vlivy, pom\u00e1h\u00e1 regulovat t\u011blesnou teplotu a umo\u017e\u0148uje hmat. Dosp\u011bl\u00fd \u010dlov\u011bk m\u00e1 v pr\u016fm\u011bru asi dva metry \u010dtvere\u010dn\u00ed k\u016f\u017ee.<\/p>\n\n\n\n

7. Va\u0161e t\u011blo se neust\u00e1le obnovuje<\/h2>\n\n\n\n

R\u016fzn\u00e9 bu\u0148ky v t\u011ble proch\u00e1zej\u00ed cykly obm\u011bny. K\u016f\u017ee se pravideln\u011b obnovuje, sliznice \u017ealudku se neust\u00e1le obnovuje a dokonce i kostn\u00ed tk\u00e1\u0148 se p\u0159estavuje. To znamen\u00e1, \u017ee se biologicky neust\u00e1le m\u011bn\u00edme.<\/p>\n\n\n\n

8. Mrk\u00e1n\u00ed je d\u016fle\u017eit\u011bj\u0161\u00ed, ne\u017e se zd\u00e1<\/h2>\n\n\n\n

Mrk\u00e1n\u00ed pom\u00e1h\u00e1 udr\u017eovat o\u010di hydratovan\u00e9 a chr\u00e1n\u011bn\u00e9. \u010clov\u011bk dok\u00e1\u017ee mrknout 15 a\u017e 20kr\u00e1t za minutu. Bez tohoto automatick\u00e9ho pohybu by o\u010di rychle vysychaly.<\/p>\n\n\n\n

9. St\u0159eva a mozek jsou propojeny<\/h2>\n\n\n\n

Mezi st\u0159evy a mozkem existuje p\u0159\u00edm\u00e1 komunikace. Stresov\u00e9 situace proto mohou zp\u016fsobovat b\u0159i\u0161n\u00ed pot\u00ed\u017ee. Toto spojen\u00ed ukazuje, jak jsou emoce a t\u011blo propojeny.<\/p>\n\n\n\n

10. T\u011blo vyza\u0159uje mal\u00e9 mno\u017estv\u00ed sv\u011btla<\/h2>\n\n\n\n

V\u00fdzkum ukazuje, \u017ee lidsk\u00e9 t\u011blo vyza\u0159uje extr\u00e9mn\u011b mal\u00e9 mno\u017estv\u00ed sv\u011btla v d\u016fsledku chemick\u00fdch reakc\u00ed v bu\u0148k\u00e1ch. Toto sv\u011btlo je pouh\u00fdm okem neviditeln\u00e9, ale lze jej detekovat speci\u00e1ln\u00edm vybaven\u00edm.<\/p>\n\n\n\n

Z\u00e1v\u011br<\/h2>\n\n\n\n

Lidsk\u00e9 t\u011blo je skute\u010dn\u00e1 biologick\u00e1 laborato\u0159 v neust\u00e1l\u00e9m provozu. Ka\u017ed\u00fd org\u00e1n, bu\u0148ka a syst\u00e9m pracuje v dokonal\u00e9 koordinaci, aby udr\u017eel \u017eivot.<\/p>\n\n\n\n

\u010c\u00edm v\u00edce o tom zji\u0161\u0165ujeme, t\u00edm v\u00edce si uv\u011bdomujeme, \u017ee se toho st\u00e1le tolik mus\u00edme nau\u010dit. Nejpodivn\u011bj\u0161\u00ed je, \u017ee s touto slo\u017eitost\u00ed \u017eijeme ka\u017ed\u00fd den, \u010dasto ani\u017e bychom si p\u0159edstavovali, jak mimo\u0159\u00e1dn\u00e1 na\u0161e vlastn\u00ed t\u011bla skute\u010dn\u011b jsou.<\/p>","protected":false},"excerpt":{"rendered":"
