Cov lub hlwb yog tsim los ntawm medulla, pons, thiab cerebellum. Lub medulla nyob ib sab ntawm tus txha caj qaum thiab tswj kev ua haujlwm sab nraud ntawm kev nco qab, xws li ua pa thiab ntshav ntws.
Raws li, peb lub hauv paus tseem ceeb ntawm hindbrain yog dab tsi?
Lub paj hlwb yog ib qho tseem ceeb tshaj plaws ntawm tag nrho lub hauv paus paj hlwb, vim nws txuas lub hlwb mus rau tus txha caj qaum thiab tswj hwm ntau yam haujlwm tseem ceeb, xws li ua pa thiab lub plawv dhia. Muaj peb ntu tseem ceeb ntawm hindbrain - pes , lub paj hlwb , thiab medulla oblongata.
Ib sab saum toj no, puas yog hindbrain tib yam li lub hlwb? Lub sij hawm lub hlwb hais txog qhov qub tshaj plaws (evolutionarily hais lus) feem ntawm peb lub hlwb, uas yog tsim los ntawm cov hlwb (ua los ntawm pons thiab medulla oblongata) thiab cerebellum.
Kuj tseem paub, dab tsi yog qhov haujlwm ntawm hindbrain?
Hindbrain, tseem hu ua rhombencephalon, thaj tsam ntawm kev loj hlob vertebrate hlwb uas yog tsim los ntawm medulla oblongata, pons, thiab lub paj hlwb . Lub hindbrain tswj kev ua haujlwm uas yog qhov tseem ceeb rau kev ciaj sia, suav nrog kev ua pa ntawm kev ua pa, kev ua kom lub cev muaj zog, pw tsaug zog, thiab tsaug zog.
Cov qauv dab tsi nyob hauv midbrain?
Cov cheeb tsam tseem ceeb ntawm midbrain yog tectum , cerebral aqueduct, tegmentum, thiab cerebral peduncles. Rostrally lub midbrain adjoins lub diencephalon ( thalamus , hypothalamus , etc.), thaum caudally nws adjoins lub lub hlwb ( pes , medulla thiab lub paj hlwb ).

Dab tsi yog cov txheej txheem txheej txheem ntawm cov pob txha ua los ntawm?
Cov txheej txheem sab nraud, uas yog ua los ntawm cov organic matrix (30%) muaj cov proteoglycans (tab sis tsawg dua pob txha mos), glycosaminoglycans, glycoproteins, osteonectin (thauj cov pob txha pob txha mus rau collagen) thiab osteocalcin (calcium khi protein)
Lub luag haujlwm ntawm cov txheej txheem mastoid thiab txheej txheem styloid yog dab tsi?
Cov txheej txheem styloid nyob rau sab xub ntiag thiab nruab nrab rau cov txheej txheem mastoid, thiab nyob nruab nrab ntawm lawv yog stylomastoid foramen. Cov foramen no tso cai rau cov leeg nqaij ntawm lub ntsej muag lub ntsej muag tawm ntawm pob txha taub hau thiab mus rau sab hauv txhawb cov leeg ntawm lub ntsej muag
