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
