Cov kab mob musculoskeletal yog cov pob txha ntawm lub cev. Lub cev pob txha tiv thaiv tib neeg lub cev los ntawm kev puas tsuaj rau tib neeg, yog li kev muaj peev xwm ntawm tus neeg tag nrho nyob ntawm nws tus mob. Hauv peb tsab xov xwm, peb yuav txiav txim siab txog cov pob txha, cov yam ntxwv ntawm lawv cov qauv thiab cov khoom tsim nyog rau lawv txoj kev loj hlob thiab kev loj hlob.
Txoj kev ntawm cov qauv ntawm cov pob txha
Pob txha yog hom kab mob sib txuas. Nws muaj cov cell tshwj xeeb thiab ntau cov khoom siv intercellular. Ua ke, cov qauv no yog ob qho tib si muaj zog thiab elastic. Hardness yog muab rau cov pob txha, ua ntej ntawm tag nrho cov, los ntawm cov hlwb tshwj xeeb - osteocytes. Lawv muaj ntau qhov kev loj hlob, nrog kev pab los ntawm kev sib txuas ua ke.
Visually, osteocytes zoo li lub network. Cov tshuaj intercellular yog lub hauv paus elastic ntawm cov pob txha. Nws yog tsim los ntawm collagen protein fibers, ib tug ntxhia hauv paus.
Cov pob txha
Ib feem peb ntawm tag nrho cov tshuaj muaj pes tsawg leeg ntawm cov pob txha yog dej. Nws yog lub hauv paus rau kev khiav ntawm tag nrho cov txheej txheem metabolic. Hardness yog muab rau cov pob txha los ntawm inorganic tshuaj. Cov no yog cov ntsev ntawm calcium, sodium, potassium thiab magnesium, nrog rau phosphorus compounds. Lawv feem pua yog 50%.
Yuav ua pov thawj lawv qhov tseem ceeb rau ib hom ntaub, koj tuaj yeem ua qhov kev sim yooj yim. Ua li no, cov pob txha yuav tsum tau muab tso rau hauv ib qho kev daws ntawm hydrochloric acid. Yog li ntawd, minerals yuav yaj. Cov pob txha ces yuav elastic heev uas yuav muab khi rau hauv ib lub pob.
25% ntawm cov tshuaj muaj pes tsawg leeg yog cov organic teeb meem. Lawv sawv cev los ntawm elastic protein collagen. Nws muab elasticity rau cov ntaub. Yog hais tias cov pob txha yog calcined tshaj tshav kub, cov dej yuav evaporate thiab cov organic teeb meem yuav hlawv. Hauv qhov no, cov pob txha yuav nkig thiab yuav tawg.
Yuav ua li cas cov pob txha tawv
Cov tshuaj muaj pes tsawg leeg ntawm cov pob txha cov ntaub so ntswg hloov thoob plaws hauv tib neeg lub neej. Thaum lub hnub nyoog hluas, cov organic teeb meem predominates nyob rau hauv nws. Thaum lub sij hawm no, cov pob txha hloov tau thiab mos. Yog li ntawd, nrog rau qhov tsis raug ntawm lub cev thiab lub cev hnyav, lub cev pob txha tuaj yeem khoov, ua rau muaj kev ua txhaum ntawm lub cev. Kev ua kis las thiab kev tawm dag zog lub cev tuaj yeem tiv thaiv qhov no.
Lub sijhawm dhau mus, cov ntxhia ntsev hauv cov pob txha nce ntxiv. Nyob rau tib lub sijhawm, lawv poob lawv elasticity. Hardness yog muab rau cov pob txha los ntawm cov ntxhia ntsev, xws li calcium, magnesium, phosphorus, fluorine. Tab sis nyob rau hauv kev thauj khoom ntau dhau, lawv tuaj yeem ua rau muaj kev ua txhaum ntawm kev ncaj ncees thiab tawg.
Calcium tseem ceeb tshwj xeeb rau cov pob txha. Nws qhov hnyav hauv tib neeg lub cev yog 1 kg ntawm cov poj niam thiab 1.5 kg ntawm txiv neej.
Lub luag haujlwm ntawm calcium hauv lub cev
99% ntawm tag nrho cov nyiaj calcium nyob rau hauv cov pob txha, tsim kom muaj lub cev pob txha muaj zog. Tus so yog ntshav. Cov macronutrient no yog cov khoom siv ntawm cov hniav thiab cov pob txha, qhov tsim nyog rau lawv txoj kev loj hlob thiab kev loj hlob.
Hauv tib neeg lub cev, calcium kuj tswj kev ua haujlwm ntawm cov leeg nqaij, nrog rau cov ntaub so ntswg plawv. Ua ke nrog magnesium thiab sodium, nws yuav cuam tshuam rau qib ntshav siab, thiab nrog prothrombin - ntawm nws cov coagulability.
Kev ua kom cov enzymes, uas ua rau cov txheej txheem ntawm neurotransmitter synthesis, kuj nyob ntawm qib calcium. Cov no yog biologically active tshuaj uas los ntawm lub impulse yog kis los ntawm cov hlwb ntawm lub paj hlwb mus rau cov leeg. Cov macronutrient no tseem cuam tshuam rau kev ua kom muaj ntau cov enzymes uas ua haujlwm ntau yam: kev tawg ntawm biopolymers, rog metabolism, synthesis ntawm amylase thiab m altase.
Calcium txhim kho qhov permeability ntawm cov cuab yeej saum npoo ntawm cov hlwb, tshwj xeeb yog lawv cov daim nyias nyias. Qhov no tseem ceeb heev rau kev thauj mus los ntawm ntau yam tshuaj thiab tswj homeostasis - qhov tsis tu ncua ntawm ib puag ncig ntawm lub cev.
khoom siv tau
Raws li koj tuaj yeem pom, tsis muaj calcium hauv lub cev tuaj yeem ua rau muaj kev cuam tshuam loj ntawm nws txoj haujlwm. Txhua hnub tus menyuam yuav tsum haus txog 600 mg ntawm cov tshuaj no, ib tug neeg laus - 1000 mg. Thiab rau cov poj niam cev xeeb tub thiab pub niam misdaim duab no yuav tsum tau nce ib thiab ib nrab mus rau ob zaug.
Cov zaub mov twg muaj calcium ntau? Ua ntej tshaj plaws, cov no yog ntau yam khoom noj siv mis: kefir, fermented ci mis nyuj, qaub cream, tsev cheese … Thiab cov thawj coj ntawm lawv yog cov cheese nyuaj. Thiab nws tsis yog tus nqi ntawm calcium, tab sis nyob rau hauv nws daim ntawv. Cov khoom no muaj mis nyuj qab zib - lactose, uas pab txhawb kom nqus tau zoo ntawm cov tshuaj no. Tus nqi ntawm calcium kuj nyob ntawm cov ntsiab lus rog. Qhov ntsuas no qis dua, qhov ntau nws nyob hauv cov khoom siv mis nyuj.
zaub kuj nplua nuj nyob hauv calcium. Cov no yog spinach, broccoli, dawb cabbage thiab cauliflower. Ntawm cov txiv ntoo, qhov tseem ceeb tshaj plaws yog almonds thiab Brazilian. Lub tsev khaws khoom ntawm calcium yog poppy thiab noob hnav. Lawv siv tau ob qho tib si nyoos thiab hauv cov mis nyuj.
Kev noj cov nplej nplej thiab ci nrog cov hmoov nplej tag nrho, kua cheese thiab mis nyuj, zaub txhwb qaib, dill, zaub basil thiab mustard kuj tuaj yeem nce calcium ntau ntxiv.
Cov tsos mob txaus ntshai
Yuav ua li cas nkag siab tias calcium hauv lub cev tsis txaus rau nws txoj kev loj hlob ib txwm? External manifestations ntawm qhov no yog tsis muaj zog, chim siab, qaug zog, qhuav tawv nqaij, fragility ntawm tus ntsia thawv phaj. Nrog rau qhov tsis muaj calcium loj, cov hniav lwj, convulsions, mob thiab loog loog ntawm cov ceg, ua txhaum ntawm cov ntshav coagulation txheej txheem, txo qis hauv kev tiv thaiv, tachycardia, kev loj hlob ntawm cov kab mob cataracts, thiab muaj feem xyuam rau cov pob txha tsis tu ncua. Hauv qhov xwm txheej zoo li no, yuav tsum pub ntshav thiab, yog tias tsim nyog, pib kho.
Yog li, dab tsi ua rau cov pob txha tawv yog lawv cov ntxhia pob zeb. Ua ntej tshaj plaws, cov no yog cov ntsev, uas suav nrog calcium, magnesium thiab phosphorus.
