Question 3

Answer 3

Kinins

Question 4

Explain 2ry Hyperalgesia ?

Answer 4

Site : healthy skin
Skin ; healthy
Site of lesion :mech: Convergence -Facilitation in spinal cord
Pain sensation : Painful become more painful
Pain threshold : Normal
الفكرة ان العصب الثاني في المسار تقابل مع العصب بتاع الالتهاب فعمله تقريب من الثيرشولد فلما تضرب علي الجلد الكويس هينقل في العصب الاول عادي لغاية العصب الثاني المستعد اصلا فيطلع فيه اكثرمن جهد حركة واصلا قوة الحركة بتعتمد علي عدد جهود الحركة الماشية للجهاز العصبي المركزي

Question 5

Hepres zoster and pain

Answer 5

بص يا سيدي الهربس ممكن يجيلك وتخف منه بس هيتسخبي منك في الدرج ؟
Dorsal root ganglion in a segment of spinal cord
المهم يفضل مستخبي متسخبي لغاية ما مناعتك تقل يقول اشطاااا! انا طالع
المهم يعمل تهييج للعقدة في الجذر الخلفي الظهري و ينشط اعصاب الألم فيها
تروح للدماغ تقوله يابا في حتة جلد بتوجعك وانت مش واخد بالك فالدماغ يقولك اه صح ! قانون الاسقاط فتبدأ الديرماتوم المسئول عنها الدرج ده توجعك
بعدين الهربس ميسكتش لأ ..!
ينتقل عن طريق العصب الطرفي لغاية مايوصل تحت الجلد
ويعملك طفح جلدي وحويصلات فيها مايه
Unilateral limited Rash and Vesicles

Question 8

Referred pain explain

Answer 8

It is called Radiating pain
يعني الالم ده بيسمع فين ؟
It is pain in area of skin supplied by the same dermatome of a diseased Viscera
meaning : Supplied by the same Dorsal root

Appendic around umbilicus
Renal ; Back and inguinal and testes
Cardiac : Retrosternal - outerchest - Neck Root - Inner arm

Question 11

Theories of radiation

Answer 11

Convergence Facilitation theory
Convergence Projection Theory

Question 12

بgr

تصبح علي خير يا غالي ^^

Answer 12

صباح الخير :)
فكان في النيل بهواءه العليل سكون للعليل

Question 13

اشرحلي Convergence Projection theory of Referred pain

Answer 13

The afferent nerves transmitting pain from skin and viscera converge on the same cell on SGR .. Stimulating pathway to the same point in the cortex and whatever was the stimul from skin or viscera it would only be felt at skin

Question 14

اشرحلي convergence Facilitation theory of referred pain
اللي عجبت عبد الحميد قوي

Answer 14

The afferent nerves from skin and diseased viscera rely on different two points on SGR then the afferent of diseased viscera faciitate the second afferent from the skin to activate its pathway fron SGR to Cortex casuing pain at skin at the same time the pathway from diseasd viscera arrive another point at cortex casuing its pain

Question 15

Why do you feel pain at skin even if it is not hurt in light of CF Theory

Answer 15

Because second order neuron at SGR from skin pathway is facilitated by nerve from the diseased viscera activiating the pathway of skin pain from SGR to Cortex casuing referred pain or Radiating الالم المسمع

Question 15

Why do you feel pain at skin even if it is not hurt in light of CF Theory

Answer 15

Because second order neuron at SGR from skin pathway is facilitated by nerve from the diseased viscera activiating the pathway of skin pain from SGR to Cortex casuing referred pain or Radiating الالم المسمع
