Cov tus txha nqaj qaum uas tawm los qaum qaum yog suav raws li vertebra ntawm lawv tawm cov qaum kem Yog li, cov qaum paj hlwb T4, tawm cov qaum kem hla lub foramen hauv 4th thoracic vertebra.
Ntxiv mus, qhov twg ua rau cov leeg txha nraub qaum tawm ntawm kab vertebral?
Cov tus txha nqaj qaum tawm ntawm vertebral kab los ntawm qhov intervertebral foraminae. Ib txhia tus txha nqaj qaum yog intermingled nyob rau hauv plexuses, los ntawm uas peripheral paj hlwb yog tsim, txhua paj hlwb muaj cov fibers los ntawm ntau qhov qaum kab txaij.
Tsis tas li ntawd, cov cheeb tsam ntawm lub cev ua rau cov hlab ntsha hauv lub cev? Cov Ncauj tsev menyuam plexus yog tsim los ntawm ventral rami ntawm plaub sab saud ncauj tsev menyuam thiab sab sauv ib feem ntawm tsib ncauj tsev menyuam ventral ramus. Lub network ntawm rami nyob sib sib zog nqus mus rau sternocleidomastoid hauv caj dab. Cov ncauj tsev menyuam plexus sab hauv cov leeg ntawm caj dab thiab thaj chaw ntawm daim tawv nqaij ntawm lub taub hau, caj dab thiab hauv siab.
Ib yam li ntawd, nws tau nug, qhov twg cov hlab ntsha tuaj tawm ntawm tus txha caj qaum?
Cov paj hlwb cag dhau tawm ntawm tus txha nqaj qaum kwj dej los ntawm lub intervertebral foramen, qhov chaw uas lawv pub lub cev anteriorly (lub cev muaj zog) los yog posteriorly (sensory). Lub anterior divisions muab rau pem hauv ntej ntawm lub qaum nrog rau cov nqua. Kev sib cais tom qab yog faib rau cov leeg tom qab qaum.
Yuav ua li cas cov hlab ntsha nkag mus thiab tawm ntawm tus txha caj qaum?
Dorsal thiab ventral cag nkag thiab tawm ntawm kab lus vertebral feem los ntawm intervertebral foramen ntawm cov vertebral ntu sib xws rau cov qaum ntu. Daim duab 8, 12, 5, 5 thiab 1 ncauj tsev menyuam , hauv siab, lub lumbar , sacral thiab coccygeal tus txha nqaj qaum thiab lawv tawm los ntawm vertebrate, feem.

Cov hlab ntsha thiab cov hlab ntsha nyob qhov twg?
Txawm hais tias txoj hlab ntsha yog ib txwm ntseeg tias taug kev hauv qhov zawj ntawm qhov tsis zoo ntawm tus tav nrog rau cov hlab ntsha thiab cov leeg leeg, cov hlab ntsha kuj tseem tuaj yeem nyob nruab nrab ntawm cov tav. Cov paj hlwb intercostal nyob tob rau hauv cov leeg nqaij intercostal thiab sab nraud rau lub pleura
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
Cov nqaij ntshiv dab tsi nyob rau sab nraub qaum sab nraub qaum?
Lub posterior compartment ntawm ob txhais ceg (feem ntau hu ua 'calf') txuas ntxiv mus rau qhov sib txawv ntawm sab nrauv thiab qhov sib sib zog nqus sib sib zog nqus los ntawm transverse intermuscular septum. Qhov loj dua, txheej sab saud ntawm cov ceg qis muaj gastrocnemius, soleus (GS) thiab cov leeg cog
