Daim tawv nqaij Analyzer: qauv, muaj nuj nqi thiab muaj nuj nqis. daim tawv nqaij lub cev

Nrog xws li ib tug lub tswv yim raws li "daim tawv nqaij analyzer", tsis yog txhua txhua tus neeg tau kev nyuaj siab. Feem ntau yog cov accustomed mus hu nws ib tug luv luv, ntau lub sij hawm. Uas yog, ntawm daim tawv nqaij. Tab sis, nyob rau hauv qhov tseeb, ob leeg lub tswvyim hais txog ib tug complex hloov khoom nruab nrog, uas yog lub peb txheej npog. Ib tug ntawm ob peb nyob rau hauv peb lub cev, uas tau yooj yim yuav kov thaum twg lub sij hawm. Tus neeg laus tib neeg daim tawv nqaij cheeb tsam yog kwv yees li 1.5 - 2.3 square meters. Ib tug loj ua ke nrog lub epidermis (txheej txheej nyob tob nto) yog 16-17% los ntawm ceeb thawj. Txawm li cas los, tag nrho cov no yuav tsum qhia koj ntxiv.

epidermis

Ua ntej ntawm tag nrho cov, sib tham txog ib daim tawv nqaij analyzer, nws yog tsim nyog los cuam tshuam rau lub epidermis xim. Nws yog peb tus outermost txheej. Tab sis yog hais tias nws yog hais lus nyob rau hauv lub tiaj lus. Nyob rau hauv qhov tseeb, lub epidermis - multilayered epithelium muab tau. Cov tuab daim tawv nqaij, uas yog tsis tau kev pab nrog rau cov plaub hau, nws muaj xws li ntau li ntau raws li 5 khaubncaws sab nraud povtseg. Txhua tus ntawm lawv yog saum toj no rau hauv lub dermis. Thiab tag nrho cov ntawm lawv nqa tawm lub barrier muaj nuj nqi.

Ib qho tseem ceeb caveat: lub epidermis yog peculiar qhov muab kho dua. Thiab qhov no yog kev cob cog rua nrog lub specifics ntawm lub tsiv teb tsaws thiab transformation ntawm lub thiaj li hu ua keratinocytes. Qhov no - lub hlwb ntawm epithelial cov ntaub so ntswg. Lawv filaments uas hais protein keratin. Nyob rau hauv tas li ntawd, nws tseem ceeb heev kom paub tias nyob rau hauv lub epidermis muaj tej yam Cheebtsam ntawm lub cev.

Tus qauv ntawm lub epidermis

Anatomy ntawm daim tawv nqaij yog heev. Tsuas yog tus epidermis (ib qho ntawm nws lub Cheebtsam) muaj xws li tsib txawv khaubncaws sab nraud povtseg. Thawj - basal. Los yog, raws li nws yog hu ua, sprout. Yuav ua li cas yog tiag tiag ib qho tseem ceeb kom paub txog lub basal txheej - yog lub fact tias nws muaj ib tug thiaj li hu ua melanosomes. Qhov no melanin granules, uas tiv thaiv peb ntawm tej yam los ntawm UV rays.

Qhov thib ob txheej yog hu ua spiny. Nws kuj muaj xws li ib tug cell loj, tab sis cov tseem ceeb tshaj plaws "cib" yuav suav hais tias tonofibrillyarny apparatus. Nws yog tus tub ntxhais hlwb kev tiv thaiv los ntawm cov neeg kho tshuab kev puas tsuaj.

Muaj yog ib tug granular txheej. 1-2 muaj li ntawm ib tug series ntawm elongated hlwb. Nws yog tsim nyob rau hauv no txheej thiab filaggrin keratolinin (structural cov nqaijrog). Thiab lawv txhawb keratinization ntawm lub epithelium. Qhov no, incidentally, yog lub feem ntau nyuab txheej txheem, uas horny daim tawv nqaij ntawm cov lo lus twg thiaj li raug nws xam qhovkev elasticity thiab lub dag lub zog.

Qhov thib plaub txheej yog lub npe hu ua tsiklovidny (los yog ci). Nyob rau hauv nws cov hlwb tsis muaj organelles los yog nuclei. Thiab nws zoo li ib tug ci ntsa iab pinkish stripe. Qhov no zoo txheej tsim rau lub qab xib taws thiab xib teg.

Thiab lub xeem - horny. Qhov no daim tawv nqaij, yog kev tiv thaiv. Nyob hlwb nyob rau hauv nws ua tsis tau. Yuav ua li cas nws yuav tsis tsimnyog, vim hais tias nws yog tsim los ntawm tuag keratinocytes. Los yog, raws li lawv yog hu ua, horny teev. Raws li qhov uas no txheej yog tuab, nyob ntawm seb lub load sib sib zog tsa rau ntawm daim tawv nqaij.

dermis

Qhov no yog - tom ntej no uas yuav tsum tau muab sau tseg xim, sib tham txog ntawm daim tawv nqaij analyzer. Vim hais tias cov dermis yog lub sij daim tawv nqaij. Thiab muab tso rau nws nyob rau hauv scientific lus - lub connective ib feem ntawm nws.

Lub dermis lus dag hauv qab no lub epidermis. Tab sis tsis ncaj nraim, lawv raug sib cais los ntawm ib tug basal membrane. Nws ntseg ib abundance ntawm cov hlab ntsha thiab fibers, yog li dermal muab los txhawb thiab trophic zog. Nws, zoo li lub epidermis muaj ob peb khaubncaws sab nraud povtseg. Txawm li cas los, vim hais tias ntawm ib tug me me muaj pes tsawg tus - muaj tsuas yog peb.

Lub Cheebtsam ntawm lub dermis

Anatomy ntawm daim tawv nqaij yog heev tham, tab sis koj muaj peev xwm nkag siab txog nws. Tsuas yog peb khaubncaws sab nraud povtseg, thiab thawj thawj tug uas tsim nyog paub - papillary. Yog vim li cas lawv hu rau nws? Vim hais tias nws yog tus thawj txheej muaj cov "papillae" uas txeem lub epidermis. Nws muaj xws li dozens ntawm "Cheebtsam". Qhov no cov ntaub so ntswg basophils, macrophages thiab ntau lwm lub hlwb uas ua rau kom qhov kev siv ntawm cov kev tiv thaiv nuj nqi ntawm peb tsis muaj zog.

Qhov thib ob txheej yog hu ua ib tug Mesh. Nws cov ntaub ntawv ib tug tuab fibrous connective cov ntaub so ntswg. Nruj me ntsis hais lus, qhov no yog - lub ntsiab yog ib feem ntawm lub dermis. Nws yog nyob rau hauv lub mesh txheej muaj cov feem ntau hwj chim collagen fibers ua rau kom siv cov nyiaj them yug muaj nuj nqi.

Qhov kawg txheej no yog hu ua cov epidermis. Nws txawm hu cov subcutaneous cov ntaub so ntswg fatty. Nws yog situated ncaj qha nyob rau hauv lub dermis. Thiab, raws li yuav tsum to taub los ntawm cov npe, tsim los ntawm fatty cov ntaub so ntswg. Nws yog vim nws nyob rau hauv daim tawv nqaij ua li dej thiab as-ham. Nyob rau hauv tas li ntawd, lub hypodermis pab thermoregulation.

Function: kev tiv thaiv thiab purification

Yog li ntawd, dab tsi yog ib daim tawv nqaij analyzer tseeb. Tam sim no nws yog ua tau mus rau cov hloov lub ce ntawm nws functions.

Tus thawj - ib tug tiv thaiv. Raws li twb tau hais, epidermis los ntawm qhov ncaj tus ntawm ib puag ncig tiv thaiv qab haus huv, ntaub so ntswg, thiab cov hlab ntsha. Cov tawv nqaij muaj sebaceous qog. Lawv txiav txim ntawm 300 000. Thiab thaum lub sij hawm lub hli lawv tso ib tug nruab nrab ntawm 500-800 grams rog. Nws lubricates qhov chaw ntawm daim tawv nqaij, tiv thaiv nws li los ntawm ntau yam kev kho mob.

Qhov thib ob muaj nuj nqi - cleansing. Ntawm daim tawv nqaij yuav paim hws. Yog li ntawd nws thiaj li los tso rau hauv lub cev ntawm ib tug kab mob rau adversely tshuaj nkag tau rau hauv nrog cov tshuaj los yog khoom noj. Interestingly, ntawm daim tawv nqaij yog hais txog 2 lab hws qog.

Cai, noj mov thiab ua tsis taus pa

Nws - kuj ntawm daim tawv nqaij analyzer zog uas ib txwm muaj rau cov tub ntxhais.

Yog li ntawd kev cai. Ntawm daim tawv nqaij cov ntshav tawm thaum sab nraum kub hauv qab no yog tej yam uas yog peculiar rau lub cev. Nws muaj cov lus rov nyhuv nyob rau hauv lub rov qab cov ntaub ntawv. Yog hais tias lub ambient kub siab heev, lub cutaneous nqaij yog relaxed, yog li ntawd cov hlab ntsha dilate thiab lub tshav kub efficiency yog nce los ntawm lub cev. Cov ntshav yuav khiav yog tseem ceev. Raws li ib tug tshwm sim - tawm fws.

Ua hwj chim muaj nuj nqi kuj ua rau qhov chaw ntawm daim tawv nqaij analyzer. Nws yog los ntawm peb cover txeem mus rau hauv lub cev, tsiaj thiab zaub cov rog. Solutions thiab cream yog absorbed vim lawv kev qauv. Tsis muaj lub zem no kom hniav zoo nkauj agents feem ntau yog hu ua "cov as-ham".

Ua pa muaj nuj nqi, nyob rau hauv tus, yog yus muaj los ntawm cov tib yam ntxwv. Vim lub ntxeem tau qauv ntawm cov sab sauv txheej ntawm daim tawv nqaij yog faib 2% carbon dioxide. Muaj tseeb tsis txhua leej txhua tus paub hais tias nyob rau hauv 24 teev peb qhia npog txog 800 grams dej vapor!

neural kev sib txuas

Saum toj no nws yog ib tug ntau hais txog dab tsi yog tib neeg daim tawv nqaij. Tus qauv thiab nws cov kev khiav dej num yog kev txaus siab. Thiab ib tug yuav tsis tab sis cuam tshuam rau cov xim lub npe ntawm qab haus huv, uas peb "plhaub" tas nruab nrog.

Yuav kom muab tso rau hauv mus siv cuag lus, daim tawv nqaij - qhov no yog ib tug zoo teb, dotted nrog receptors. Lawv yog lossi, txhua txhua ob, perceive stimuli ntawm cov xwm sib txawv los ntawm lub sab hauv thiab sab nraud ib puag ncig.

Paj fibers thiab kaw (ob encapsulated thiab dawb) - qhov no yog dab tsi Ntau muaj xws li tib neeg daim tawv nqaij. Qauv thiab lawv cov kev khiav dej num. Lub paj hlwb nyob rau hauv lub epidermis thiab dermis. Lub hypodermis lawv yog yuav luag muaj. Nyob rau hauv nws xwb txeem paj yeej txoj kev ua plexus ntawd, ntawm uas cov fibers cuag mus rau hauv lub dermis. Los yeej muaj - mus rau lub hauv paus plaub hau, cov leeg, cov hlab ntsha thiab hws qog.

Lub paj txoj muaj lawv tus kheej npe. Piv txwv li, ua tsaug rau flasks Krause daim tawv nqaij hnov zoo li no. Ib tug Meissner corpuscles pab rau lub xaav ntawm kov. Vim Ruffini corpuscles peb sov. Daim ntawv teev cov yuav ua tau ntev. Tab sis qhov tseem interesting tshaj plaws yog hais tias nyob rau hauv ib tug square centimeter ntawm daim tawv nqaij tso nyiaj rau txog 200 mob, tshav kub 2, 12 thiab 20 ntawm txias tactile receptors.

ntshav

Lawm, tus qauv ntawm daim tawv nqaij analyzer nws muaj nws ib qho nta, ua tsaug rau uas cov ntshav ncig.

Yog li ntawd, nyob rau hauv lub hypodermis, nyob rau hauv tas li ntawd mus paj fibers thiab txoj yog loj hlab ntsha. Muaj txawm ib leeg. Lawv xeeb los ntawm lub thiaj li hu ua arterial network, nyob saum lub fascia. Kuv tham txog lawv nyob rau hauv thaum pib.

Los yeej muaj, tus arterial network ncua ntxiv - nyob rau hauv lub deepest qhov chaw ntawm lub reticular txheej. Thiab los ntawm muaj - ncaj nraim rau lub papillary.

Nws yog ib qho tseem ceeb kom paub hais tias daim tawv nqaij khaubncaws sab nraud povtseg yog tsis tsuas cov hlab ntsha thiab venules, thiab arterioles, thiab tshaj. Leej twg tau ncaj qha kev koom tes nyob rau hauv cov kev cai ntawm muaj quag vascular kuj (tag nrho cov peripheral vascular kuj). Arteriolar laus yog qho tseem ceeb heev. Tom qab nyob peripheral kuj, uas txiav txim ntshav siab los ntawm nws. Ntawm no yog cov yam ntxwv ntawm daim tawv nqaij analyzer. Txawm li cas los, nws tsis yog xav tsis thoob. Tom qab tag nrho, peb yuav tau tham txog ib zaug xwb, tag nrho cov kab mob, nyob rau hauv uas kiag li txhua yam yog sib thooj,.

rhiab heev

No lub ntsiab yog tseem muaj nqis ntsoov teev cov xim. Muaj xws li ib tug tshaj plaws raws li ib tug tawv-nqaij rhiab heev. Nws cov keeb kwm yog ib qhov tseeb. Tom qab tag nrho, feem ntau nyob rau hauv cov nqaij muaj feem xyuam rau kov ub kov no yav tas los rau ntawm daim tawv nqaij. Noj, piv txwv li, tib zaws.

Tab sis tshwj xeeb daim tawv nqaij rhiab heev. Nws yog tsim los ntawm cov sib txawv analyzers. Qhov kev txiav txim ntawm kov, rau Piv txwv li - yog ib tug complex lawm uas tshwm sim los ntawm txoj kev xav ntawm kev kawm. Tactile ncus ua si ib qho tseem ceeb luag hauj lwm no. Analyzers, perceiving siab thiab kov, muab peb cov lus qhia txog tus kwv ceev, nws zoo lawm, kub, kev mob, loj, me, thiab ntau dua. Tshwj xeeb tshaj yog muaj ntau receptors yog feeb meej nyob rau ntawm lawv cov ntsis ntiv tes. Nws yog rau lawv pib lub "txoj kev" ntaub ntawv Pib ntsais koj teeb kis tau mus rau lub hlwb.

lwm

Nws yog ntawm ob hom. Tus thawj yog hu ua physiological. Nws yog ib tug ib txwm, tej yam ntuj tso txoj kev uas yuav cell daim ntawv rov ntxiv. Nws tshwm sim nyob rau cov zaub mov, lub cev noj qab haus huv thiab tib neeg tiv thaiv. Qhov no, nyob rau hauv lem, kev cuam tshuam rau cov tsos thiab hluas zog tuaj ntawm daim tawv.

Ib tug reparative lwm implies cover restoration tom qab txhua yam kev puas tsuaj. Tom qab muab hlais tawm lawm, piv txwv li. Tus txheej txheem yog heev nthuav. Thawj theem ntawm lub o tshwm sim - tsis los ntshav, o tshwm sim, nias rau qab haus huv thiab yuav ua tau rau mob. Ces, loj hlob pib. Cov txhab uas muaj cov hlab ntsha thiab connective cov ntaub so ntswg - li collagen. Cov theem kawg yuav lub tsim ntawm caws pliav. Nws tub num tsoom sau tus txheej txheem ntawm sau qhov chaw ntawm yeej epithelial cov ntaub so ntswg.

Ib txhia nti yuav tau ua txhua xyoo. Thiab cia ntawm daim tawv nqaij yus tsuaj, tsis muaj ib tug kab ntawm kev puas tsuaj tsis dhau. Vim hais tias nws yuav tsum tau kho nrog saib xyuas.

nthuav lus tseeb

Lawv yuav tsum ua tiav rau zaj dab neeg uas yog ib tug tawv-nqaij rhiab heev (cov qauv ntawm cov analyzer thiab nws muaj nuj nqi, peb kuj saib). Tseeb, ib co nthuav cov lus tseeb, thiab hais tias ib yam ntawm lawv yog noteworthy:

• Nws yog ib qhov nyuaj rau xav txog tej yam tag nrho saum npoo ntawm peb cov tawv nqaij yog hais txog li tsib lab cov plaub mos mos!
• Nyob rau hauv cov neeg laus tib neeg daim tawv nqaij los ntawm 60% muaj dej. Cov me nyuam - mus txog rau 90% (tab sis qhov no yog lub siab tshaj plaws).
• Ib square centimeter ntawm daim tawv nqaij ntog rau hauv 100 ces.
• Nyob rau nruab nrab cover nce mus txog 1-2 millimeters nyob rau hauv thickness.
• Nws yog ib lub ntxhib daim tawv nqaij nyob rau hauv lub qab xib taws. Feem ntau cov nyias thiab pob tshab - nyob rau tawv muag.
• Thoob plaws hauv nws lub neej, hais txog 18 kilograms ntawm hard daim tawv nqaij yog hloov los ntawm ib lub tshiab.

Zoo, koj muaj peev xwm qhia rau ib tug ntau nthuav ntau yam uas hais txog peb npog, nws cov qauv thiab cov kev nta. Tab sis qhov yooj yim lub cev ntawm cov kev cai uas teev tseg saum toj no, thiab yuav pab tau kom koj nco ntsoov txhua leej txhua tus, vim hais tias lub npe kev txhawj xeeb rau peb tag nrho cov ncaj qha.
