السلام عليكم و رحمة الله و بركاته
أرحب بكم أعزائي اطباء المستبقل و أشارككم بأول موضوع لي في هذا المنتدى الجميل!
و بدون المزيد من المقدمات أقدم لكم how to pith & dissect a frog
a- Pithing: Damaging the nerve system NS
Before Dissecting the from we need to PITH it
1st step:Blow the frog's head with a heavy object (Don't use chemicals in order not to harm the frog's internat organs) a
2nd Step: Use your needle (in dissecting set ) to enter the (OCCIPITO-VERTABRAL GROOVE located: behind the eyes on the median plane and feels like a deppression) at an angle in order to destroy the spinal cord and brain, and move in circular motion
P.S in order to make sure your frog is completley pithed>>> check its Corneal reflex by touching the frog's eye>>>if frog does NOT blink then the brain is damaged
if the legs dont move >>> this means the spinal cord is damaged
and now you are ready for dissecting
Benifits of Pithing: the frog wont feel pain, and it cannot move during dissection
إنشاء الله أكون أفدتكم
طبعا هذه الخطوات من فهمي للتشريح...و إن شاء الله تفهموها و إن وجدتوا بعض الصعوبات لا تتردوا ... فأنا موجود في خدمتكم
و شكرا لكم
و ان شاء الله اكملكم الدايسكشن قريبا
