1. Common Carotid Artery
Wax walba waxay ka bilaabmaan Common Carotid Artery.
Waxaa jira laba dhinac:
- Right Common Carotid Artery
- Left Common Carotid Artery
Labadaas waxay dhiig u keenaan madaxa iyo qoorta.
Markay qoorta kor ugu socdaan, mid kasta wuxuu ku dhammaadaa isagoo u kala baxa laba artery:
External Carotid Artery
iyo
Internal Carotid Artery
Waxaan hadda raacaynaa Internal Carotid Artery.
2. Internal Carotid Artery — qaybta qoorta
Internal Carotid Artery wuxuu ka bilaabmaa meesha uu Common Carotid Artery ku kala baxo.
Wuxuu qoorta kor ugu socdaa isagoo u socda madaxa.
Waxa muhiimka ah:
Internal Carotid Artery qaybta qoorta badanaa laamo muhiim ah kama bixiyo.
Wuxuu u sii socdaa madaxa si uu dhiigga ugu geeyo:
- maskaxda
- isha
3. Carotid Canal
Markuu Internal Carotid Artery gaaro salka skull-ka, wuxuu galaa Carotid Canal.
Carotid Canal waa tunnel ku dhex jira:
Petrous Part of Temporal Bone
Haddaba saddexdaas kala saar:
- Temporal Bone = laf
- Petrous Part of Temporal Bone = qayb adag oo ka mid ah laftaas
- Carotid Canal = tunnel ku dhex jira qaybtaas
- Internal Carotid Artery = artery-ga dhex maraya tunnel-ka
4. Petrous Part of Internal Carotid Artery
Qaybta Internal Carotid Artery ee ku dhex socota Carotid Canal waxaa loo yaqaan:
Petrous Part of Internal Carotid Artery
Inta uu ku jiro carotid canal, wuxuu ku dhex socdaa lafta petrous-ka.
Qaybtani waa qayb ka mid ah skull base, mana aha qaybta maskaxda lafteeda.
Waxaa muhiim ah:
Internal Carotid Artery halkan wuxuu BADANAA MARAYAA, ma aha meesha uu ku bixinayo laamihiisa waaweyn ee maskaxda.
5. Ka dib Carotid Canal
Markuu Internal Carotid Artery ka soo gudbo carotid canal, wuxuu u sii gudbaa gudaha skull-ka.
Wuxuu xiriir dhow la yeeshaa:
Cavernous Sinus
6. Cavernous Sinus
Cavernous Sinus waa meel venous ah oo ku taal salka gudaha skull-ka.
Waxay ku dhowdahay:
Sella Turcica
Sella Turcica waa meesha ku taalla Pituitary Gland.
Cavernous Sinus wuxuu ku yaallaa labada dhinac ee Sella Turcica.
Waxa kale oo uu ku dhow yahay Middle Cranial Fossa.
7. Cavernous Part of Internal Carotid Artery
Marka Internal Carotid Artery uu dhex maro Cavernous Sinus, qaybtaas waxaa loo yaqaan:
Cavernous Part of Internal Carotid Artery
Halkan artery-gu wuxuu sameeyaa qalloocyo.
Sidaas darteed hadda waa inaad kala garataa:
Petrous Part
Internal Carotid Artery wuxuu ku jiraa Carotid Canal, gudaha Petrous Part of Temporal Bone.
Cavernous Part
Internal Carotid Artery wuxuu dhex maraa Cavernous Sinus.
8. Nerves-ka la xiriira Cavernous Sinus
Cavernous Sinus waa meel aad muhiim u ah sababtoo ah nerves badan ayaa ku dhow.
Waxaa ka mid ah:
Oculomotor Nerve
Trochlear Nerve
Ophthalmic Nerve
Maxillary Nerve
Abducens Nerve
Laakiin dhammaantood ma aha laamo ka yimaada Internal Carotid Artery.
Tusaale:
Oculomotor Nerve = nerve
Trochlear Nerve = nerve
Ophthalmic Nerve = nerve
Maxillary Nerve = nerve
Abducens Nerve = nerve
Halka:
Internal Carotid Artery = artery.
9. Internal Carotid Artery wuxuu ka baxaa Cavernous Sinus
Markuu ka gudbo qaybta cavernous, Internal Carotid Artery wuxuu u gudbaa qaybta intracranial.
Halkan ayuu muhiimaddiisu aad u weynaanaysaa.
Sababtoo ah hadda wuxuu bilaabayaa inuu bixiyo laamaha dhiigga u qaada maskaxda iyo isha.
10. Ophthalmic Artery
Mid ka mid ah laamaha muhiimka ah waa:
Ophthalmic Artery
Tani waa laan ka timid Internal Carotid Artery.
Waxay u socotaa orbit-ka.
Waxay dhiig siisaa qaabab ay ka mid yihiin:
- eyeball
- optic nerve qayb ka mid ah
- retina
- orbital structures kale
Waxay gashaa orbit-ka iyadoo maraysa:
Optic Canal
Halkaas waxaa jira laba qaab oo aad muhiim u ah:
Optic Nerve
iyo
Ophthalmic Artery
Labaduba waxay maraan Optic Canal.
Laakiin:
Optic Nerve ma aha laan ka timid Internal Carotid Artery.
Ophthalmic Artery waa laan ka timid Internal Carotid Artery.
11. Posterior Communicating Artery
Internal Carotid Artery wuxuu kaloo bixiyaa:
Posterior Communicating Artery
Artery-gan wuxuu xiriirinayaa qaybta hore ee wareegga dhiigga maskaxda iyo qaybta dambe.
Wuxuu qayb ka yahay:
Circle of Willis
12. Anterior Choroidal Artery
Internal Carotid Artery wuxuu sidoo kale bixiyaa:
Anterior Choroidal Artery
Artery-gan wuxuu dhiig siiya qaybo qoto dheer oo maskaxda ah.
Waxa ka mid ah qaybo la xiriira:
- optic tract
- lateral geniculate body
- qayb ka mid ah internal capsule
- qaybaha medial temporal region
Sidaas darteed Internal Carotid Artery wuxuu leeyahay laamo badan oo shaqooyin kala duwan leh.
13. Dhammaadka Internal Carotid Artery
Hadda waxaan gaaraynaa meesha aad markii hore iga weydiisay:
“Anterior Cerebral Artery iyo Middle Cerebral Artery xaggee bay joogaan?”
Marka Internal Carotid Artery uu gaaro dhammaadka qaybtiisa intracranial, wuxuu u kala baxaa laba laamood oo waaweyn:
Anterior Cerebral Artery
iyo
Middle Cerebral Artery
Kuwani waa terminal branches ee Internal Carotid Artery.
14. Anterior Cerebral Artery
Anterior Cerebral Artery wuxuu u socdaalaa dhinaca hore iyo gudaha maskaxda.
Wuxuu dhiig siiya qaybaha medial surface ee:
- frontal lobe
- parietal lobe
Gaar ahaan wuxuu door weyn ku leeyahay qaybaha medial-ka maskaxda ee la xiriira lugta.
15. Middle Cerebral Artery
Middle Cerebral Artery wuxuu u socdaalaa dhinaca lateral-ka maskaxda.
Wuxuu dhiig siiya qayb weyn oo ka mid ah:
- frontal lobe
- parietal lobe
- temporal lobe
Sidaas darteed markii aad i weydiisay:
“Internal Carotid Artery temporal lobe ma waraabiyaa?”
Jawaabtu waa:
Haa, Internal Carotid Artery wuxuu qayb ka qaataa dhiigga temporal lobe, gaar ahaan isagoo adeegsanaya laamihiisa sida Middle Cerebral Artery iyo Anterior Choroidal Artery.
Laakiin ma aha in la yiraahdo temporal lobe oo dhan Internal Carotid Artery ayaa waraabiya. Qaybo ka mid ah temporal lobe waxaa sidoo kale dhiig siiya Posterior Cerebral Artery.
16. Haddaba Middle Cranial Fossa xaggee ayay ku jirtaa?
Tani waa meesha aan rabay inaan si cad kuugu xiro wax walba.
Middle Cranial Fossa waa qayb ka mid ah floor of cranial cavity.
Ma aha maskaxda lafteeda.
Temporal Lobe ee maskaxda wuxuu ku yaallaa gudaha cranial cavity, wuxuuna ku dul yaallaa gobolka middle cranial fossa.
Internal Carotid Artery wuxuu maraa gobolkaas isagoo qaybihiisa skull-base-ka ah iyo cavernous segment-ka uu ku jiro.
Laakiin:
Middle Cranial Fossa ma aha meesha Internal Carotid Artery uu ku dhammaysto.
Wuxuu halkaas ka sii gudbaa ilaa uu gaaro qaybtiisa intracranial, halkaas oo uu ka bixiyo laamaha maskaxda.
17. Safarka oo dhan hal mar
Hadda isku xir dhammaan casharka:
Common Carotid Artery
waxaa laga helaa qoorta.
Waxay u kala baxdaa:
External Carotid Artery
iyo
Internal Carotid Artery
Kadib Internal Carotid Artery wuxuu kor ugu socdaalaa qoorta.
Wuxuu galaa:
Carotid Canal
oo ku dhex yaalla:
Petrous Part of Temporal Bone
Qaybta artery-ga halkaas ku socota waxaa la yiraahdaa:
Petrous Part of Internal Carotid Artery
Kadib wuxuu gaarayaa:
Cavernous Sinus
Qaybta artery-ga halkaas ku socota waxaa la yiraahdaa:
Cavernous Part of Internal Carotid Artery
Kadib wuxuu ka baxaa Cavernous Sinus oo wuxuu galaa qaybta intracranial.
Halkaas wuxuu bixiyaa:
Ophthalmic Artery
Posterior Communicating Artery
Anterior Choroidal Artery
Kadib dhammaadkiisa wuxuu u kala baxaa:
Anterior Cerebral Artery
iyo
Middle Cerebral Artery
Labadan waxay dhiig u qaadaan qaybo badan oo maskaxda ah.
Xusuusta ugu muhiimsan
Petrous Part
= gudaha Carotid Canal
Cavernous Part
= gudaha Cavernous Sinus
Ophthalmic Artery
= laan ka timaadda Internal Carotid Artery, waxayna u socotaa orbit-ka
Anterior Cerebral Artery
= terminal branch
Middle Cerebral Artery
= terminal branch
Optic Nerve
= nerve, ma aha laan artery
Middle Cranial Fossa
= qayb ka mid ah skull base, ma aha maskaxda lafteeda.
Tani waa silsiladda aad hadda maskaxda ku hayn karto:
Qoorta → Carotid Canal → Petrous Part → Cavernous Sinus → Cavernous Part → Intracranial Part → Ophthalmic Artery + laamo kale → Anterior Cerebral Artery + Middle Cerebral Artery → maskaxda.
