Periosteal cov hlab ntsha
Periosteal cov hlab ntsha yog cov cov hlab ntsha ntawm periosteum tshwj xeeb tshaj yog ntau hauv qab cov leeg thiab ligamentous txuas. Hauv qab periosteum lawv faib ua cov ceg ntoo thiab yog li nkag mus rau Volkmann cov kwj dej kom muab cov sab nrauv ib feem peb (1/3) ntawm lub cortex.
Tsis tas li lo lus nug yog, dab tsi yog txoj haujlwm ntawm cov hlab ntsha?
Lub hauv paus cov leeg kuj hu ua cov hlab ntsha nkag mus rau hauv cov pob txha los ntawm foramen thiab ceg ntoo rau hauv tus lej me dua cov hlab ntsha thiab arterioles muab cov cheeb tsam siab tshaj plaws ntawm cov pob txha neeg laus. Nws txhawb nqa cov ntshav siab kom mus txog qhov chaw nyob deb, feem ntau xaus rau hauv cov hlab ntsha tam sim no hauv metaphysis thiab endosteum.
Tsis tas li, cov pob txha puas muaj cov hlab ntsha? Skeleton Feem ntau cov pob txha muaj lub hauv paus tseem ceeb cov leeg thiab cov hlab ntsha uas nkag mus rau thaj tsam nruab nrab ntawm cov ncej los ntawm qhov hu ua cov khoom noj khoom haus, tab sis cov hlab ntsha kuj nkag mus rau hauv cov hlab ntsha. pob txha hauv lwm qhov chaw, tshwj xeeb tshaj yog nyob rau ob sab ntawm kab epiphyseal.
Zoo sib xws, nws tau nug, cov ntshav xa mus rau pob txha yog dab tsi?
Cov ntshav txaus rau pob txha yog xa mus rau endosteal kab noj hniav los ntawm cov hlab ntsha, ces ntws los ntawm cov pob txha sinusoids ua ntej tawm ntawm ntau me me. cov nkoj uas ramify los ntawm lub cortex.
Cov pob txha ntev li cas thiaj tau txais nws cov ntshav?
Hauv ib qho raug pob txha ntev , ntshav yog muab los ntawm peb lub tshuab cais: cov hlab ntsha muaj zog, cov hlab ntsha periosteal, thiab cov hlab ntsha epiphyseal. Cov mis nyuj contraction ntshav sab nraud, muab qhov centrifugal qauv ntawm ntws los ntawm cov as -ham cov hlab ntsha los ntawm cortex thiab tawm los ntawm cov leeg txuas.

Dab tsi yog qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha capillaries?
Piav qhia: Cov hlab ntshav nqa ntshav nyob hauv siab los ntawm lub plawv mus rau cov kabmob thiab cov nqaij. Lawv cov phab ntsa feem ntau yog tuab dua li cov leeg. Capillaries yog qhov sib txuas ntawm cov hlab ntsha thiab cov leeg thiab me me heev, Cov ntaub so ntswg qee zaum pom tawm thiab rov nco qab los ntawm cov qog ntshav thiab rov qab los rau cov leeg ntshav
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Dab tsi yog cov hlab ntsha thiab cov hlab ntsha capillaries?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Dab tsi yog cov hlab ntsha tseem ceeb ntawm cov hlab ntsha?
Cov hlab ntsha, cov hlab ntsha thiab lymphatic system yog cov hlab ntsha tseem ceeb hauv lub cev circulating system. parasympathetic - lub luag haujlwm rau vasoconstriction
