Step 1: Primary Autopsy Incisions. Primary incisions are initial cuts to access body cavities. Common types include:
- I-shaped (D): Vertical cut from neck to pubic bone.
- Y-shaped (B): Incisions from shoulders meet at sternum, then to pubic bone. This is the most common.
- Modified-Y (C): A variation of the Y-incision.
Step 2: Non-Standard Incisions.
- U-shaped (A): Not a standard primary incision for full autopsy.
- T-shaped (E): Also not a standard primary incision.
Step 3: Conclusion. Standard autopsy procedures use Y-shaped, I-shaped, and Modified-Y incisions as primary types. U-shaped and T-shaped incisions are not primary. Therefore, A and E are correct.
