Diagnostic Features of Histology Slides

موضوع مهم جدا..

عشان تفهم النظري كويس وعشان تحل في العملي كويس لازم تكون حافظ العلامات المميزة لكل شريحة..

مهو دة هيتكتب إن شاء الله في الكومينتس اللي بتتطلب منك بعد ما تكتب اسم الشريحة اللي شفتها تحت الميكروسكوب..

عشان كدة الموضوع دة مهم جدا ولازم يتحفظ صم..
وربنا معانا كلنا يا رب..

Diagnostic features

1-Thyroid gland:
