Lub paj hlwb loj venous sinuses. Lub cavernous sinuses yog inferior mus rau superior sagittal sinus nyob rau hauv lub hauv paus ntawm lub pob txha taub hau (Fig. 39-6). Cov kab mob hauv cov sphenoid thiab ethmoid sinuses tuaj yeem kis mus rau cov kab mob hauv lub qhov ntswg ntawm cov hlab ntsha me me, ua rau cov kab mob septic cavernous sinus thrombosis.

Dab tsi yog qhov tsis zoo ntawm lub qhov ntswg?

Lub inferior sagittal sinus yog ib lub dural venous sinuses thiab khiav raws qhov qis (dawb) ntug ntawm falx cerebri 1. Nws khiav ntawm anterior mus rau posterior, tib yam li lub superior sagittal sinus, thiab ntws mus rau hauv lub qhov ntswg ncaj.

Dab tsi yog qhov ua haujlwm ntawm qhov tsis zoo sagittal sinus?

Tus kab mob qis qis (tseem hu ua qhov ua tsis tau ntev ntev), nyob rau hauv tib neeg lub taub hau, yog thaj chaw hauv qab lub hlwb uas tso cai rau cov ntshav ntws tawm sab nraud los ntawm qhov nruab nrab ntawm lub taub hau..

Dab tsi yog qhov zoo tshaj sagittal sinus hauv lub hlwb?

Lub superior sagittal sinus (tseem hu ua superior longitudinal sinus), nyob rau hauv tib neeg lub taub hau, yog thaj chaw tsis sib xws raws cov npoo txuas ntawm falx cerebri Nws tso ntshav rau ntws los ntawm sab nraud ntawm lub paj hlwb hemispheres mus rau qhov sib txuam ntawm cov sinuses.

Yuav ua li cas rau qhov inferior sagittal sinus?

Cov kab mob tsis zoo sagittal yog tsim nyob rau hauv dawb ntug ntawm falx cerebri los ntawm kev sib txuas ntawm cov hlab ntsha ntws cov falx cerebri thiab khoob rau hauv qhov chaw ncaj. Lub sphenoparietal sinus txuas ob qho tib si rau lub cavernous sinus thiab mus rau superior sagittal sinus.
