The umbilicus is the central landmark on the abdomen, often used as an entry site for laparoscopy and as a landmark for midline laparotomy incisions.[1][2][3]
Component Tissues
| Tissue | Layer/Position | Key Properties |
|---|---|---|
| Skin | Superficial | Minimal subcutaneous tissue; nearly direct contact with fascia at center |
| Umbilical fascia | Central | Provides characteristic "pop" tactile feedback on penetration |
| Transversalis fascia | Deep | Requires recognition and penetration |
| Peritoneum | Deepest | Entry confirmation through peritoneal breach |
