Development of arteries Flashcards

فلما أن جاءه البشر ألقاه علي وجهه فارتد بصيرا قال ألم أقل لكم إني أعلم من الله مالاتعلمون
Asthma
◼ Asthma is a Heterogeneous disease characterized
by chronic airway inflammation.
◼ It is defined by the history of respiratory symptoms
such as wheeze, shortness of breath, chest
tightness, and cough, that vary overtime and in
intensity.
◼ Together with variable expiratory airflow limitation
(i.e. difficulty breathing air out of the lungs)
Type 2 Asthma ?
- allergic
- aspirin exacerbated late onset eosiophilic ashtma
Non type 2 athma ?
Obesity
Pacugrenulocte mediated asthma smooth muscles medaiated
smoking mediated neutrophilic asthma
Factors that influence the risk of
asthma can be divided into:
• Host Factors: those that cause the development of
asthma
• Environmental Factors: those that trigger asthma
symptoms
How is asthma diagnosed?
Diagnosis should be based on: I- History of Present illness II- Past medical history III- Family history IV- Physical examination V -Investigations
• Only hepatocytes and enterocytes
can effectively excrete cholesterol from
the body.
Some of the cholesterol in the intestine
is modified by bacteria before excretion,
giving rise to coprostanol (the major
sterol in stools)
All tissues especially liver, intestine, adrenal cortex, and reproductive
tissues.
• All the carbons provided by acetyl CoA
• It needs NADPH and ATP in the synthesis.
Synthesis requires enzymes in both the cytosol and the
membrane of the smooth endoplasmic reticulum (ER)
indication of hydralazine artriolar VD
- HF: with nitrates but ACEI is better
2. Hypertension: IV in eclampsia
Mention the sets of aortic vessles ?
the aortic sac the dilated cranial part of TA truncus arteriosus it is
Ventral to pharynx
the 2 dorsal aortae passing dorsal to the primitve gut then unite caudally to form single dorsal aorta
the aortic arches 6 pairs connecting the dorasal aorta to the ventral aortic sac each pair runs in the coressponding pharyngeal archalong the side of pharynx
Arch or aorta is multiple source vessel ?
This due to its formation by the stem and left horn of the Aortic Sac
proximal part of the arch!
and middle fromt the left 4th arch
distal by the left dorsal aorta part between the 4th arch and the left 7th intersegmental artery
The bracicephalic artery source?> conitues as?>
The right horn of aortic sac and
contiues with the
right subclavian and
right common carotid artery
Dorsal aorta give intersgmental arterirs what are they ?
They are arterirs passing between somites to supply the body wall muscles and skin like thoracic wall edx: intercostal arteries
Dorsal aorta give lateral splanchnic arteris what are they ?
arteries supplying the intermediate cell mass mesoderm like urogenital system
like renal arteris
Dorsal aorta give ventral splanchmic arterirs what are they ?
arteries supplying the gut
1- the vitlline supplying the gut
2-umbilical function during ebryogensis after birth they are obliterated
Dorsal aorta give ventral splanchmic arterirs what are they ?
arteries supplying the gut
1- the vitlline supplying the gut
2-umbilical function during ebryogensis after birth they are obliterated
Vitlline arteries Remenatnts mention ?
supply yolk sac and gut
1- Coeliac Trunlk foregut
2-Superior Mesenteric artery midgut
3-inferior mesenteric artery hindgut
Umbilical artery connect ?
the placenta with develooping viscera
First and second origin of the Umbilical artery
1st dorsal aorta
2nd common iliac artey
fate of the umbilical artery ?>
the proximal part forms internal iliac artery
the distal part contiues as the umbilical artetry
External iliac source?:
its orginated as a bud from the common iliac artery
Dorsal aorta gives?
intersegmental
lateral splanchnic
visceral splanchnic

عَن أَبِي هُرَيْرَةَ رضي الله عنه أَنَّ رَسُولَ اللهِ ﷺ قَالَ: (مَنْ كَانَ يُؤمِنُ بِاللهِ وَاليَوْمِ الآخِرِ فَلْيَقُلْ خَيْرَاً أَو لِيَصْمُتْ، وَمَنْ كَانَ يُؤمِنُ بِاللهِ وَاليَومِ الآخِرِ فَلْيُكْرِمْ جَارَهُ، ومَنْ كَانَ يُؤمِنُ بِاللهِ واليَومِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ) رواه البخاري ومسلم.
