Forensic Medicine: Bone Identification

2011-01-28



Assalamualaikum w.b.t


Buat sahabat2 yang study Forensic Medicine & Toxicology sekarang ni, ni saya ade siapkan table untuk bone identification. Usually bone identification ni kita study samada grossly means via bones or kita study radiologically via x- rays films. Saya ringkaskan daripada buku Forensic Medicine & Toxicology by Krishnan Vij. Buku ni salunya di gunakan oleh student2 yg pakai syllabus India eg: Banglore IMS, Shah Alam IMS and Manipal.

Semoga sama2 mendapat manfaat InsyaAllah :)
