Wound healing ❤️‍🩹

لو كان الجرح mild مجرد الي يصير هو ان الجرح يطيب بدون الحاجة لfibrous tissue الخلايا الي بجوار الinjury parenchyma cells تبدي يصيرلها proliferation and differentiation وتكون الخلايا الاصلية بينما لو كان الجرح كبير مثل الحروق او بالعمليات الجراحية severe injury لا هنا الجرح deep ف يتكون مثل gap هذا الgap تجي الfibroblast تبدي تكون collagen type 3 هواي علمود تعوض عن الtissue الي صارله damage لكن بعدين collagen type3 converted into collagen type1 to strength the scar فتكون بالنهايةاكو ندبة Scar tissue وطبعا تعتمد على نوع الخلايا اكو خلايا ما يصيرلها regeneration مثل عظلة القلب

4) A 28-year-old woman complains of fatigue that
increases throughout the day. At the end of her work-day, she says her eyes feel “heavy” and “droopy,” although she does not feel particularly tired. Pyridostigmine is prescribed to treat her myasthenia gravis. Which of the following is a potential side effect
of this therapy?

answer is B: Diaphoresis. Myasthenia gravis is
characterized by muscle weakness caused by autoantibodies blocking nicotinic acetylcholine receptors on
skeletal muscle. Pyridostigmine is an acetylcholinesterase inhibitor, potentiating the effects of acetylcholine
released into the neuromuscular junction. This excess
acetylcholine can overcome the effects of antibodies
blocking some of the receptors. Pyridostigmine will
block acetylcholinesterase throughout the body,
however, not only at the neuromuscular junction.
This can lead to cholinergic symptoms such as dia-
phoresis, miosis, diarrhea, bradycardia, and urination.
(A) Constipation is a common side effect of opioids, but
increasing acetylcholine with pyridostigmine use would
cause increased GI motility leading to diarrhea. (C) This is an adrenergic side effect. (D) This is an adrenergic side effect. (E) This is an adrenergic side effect.

الوقت المثالي للدراسة يكون ما بين الرابعة صباحا للعاشرة صباحا تعرفون ليش لان adrenal gland تحديدًا الكوتيكس تبدي تفرز الكورتيزول بوقت من 4 الصبح لحد ما يوصل الpeak الثامنة صباحا ويبدي يقل تدريجيًا لهيج نشوف اكو اتفاق عالمي الامتحانات للطلاب لازم تكون عند الثامنة صباحا 😭😍
الكوتيزول يزيد تحفيز الادرينالين و NE وذول يزيدون من activity of reticular formation تحديدا RAS او ascending reticular formation الي تنقل الاشارات العصبية نحو cerebral cortex الدماغ وبالتالي تخليك more awareness 😍😎وحتة الدماغ هنا يبدي يحول الذاكرة قصيرة الامد نحو الذاكرة طويلة الامد وحتة تشوفون اغلب المرضى اذا يشتكون يشتكون بليل من الالم الي سنه يوجعة جماعة المفاصل، المرة الحامل تجيب غالبا بليل تعرفون شنو السبب؟ شاركونا😍😅❤️

هاي القناة بيها كورسات يمكن اسعارها توصل لالف ونص دولار

بس كون جهازك تفرغه لان اذا تنزلهن كلهن تحتاج ما يقل عن واحد تيرا😂😂😂

This is what happened to your eye in morphine addiction 😕
Pint point miosis😳

9) A 40-year-old woman presents with a painless lesion on her right ear lobe (shown in the image). She reports that her ears were pierced 4 months ago. Which of the following best explains the pathogenesis of this lesion?

The answer is E: Maturation arrest of collagen assembly. Keloid is an exuberant scar that tends to progress beyond the site
of initial injury and recurs after excision. Dark-skinned persons are more frequently affected by keloids than light-skinned people. Keloids are characterized by changes in the ratio of type III to type I collagen, suggesting a “maturation arrest”
in the healing process. Further support for maturation arrest
as an explanation for keloids and hypertrophic scars is the
overexpression of fi bronectin in these lesions. Keloids are
unsightly, and attempts at surgical repair are always problematic.
The other choices do not address the pathogenesis of keloids.
Diagnosis: Keloid
