Anatomy Bones and Muscles · MU Pleven

216. Topographico-anatomical regions of the abdomen.

Covers the ventro-lateral abdominal wall, starting with its boundaries above, laterally and below, then the layers from skin through the superficial fascias, the oblique and transverse muscles, transversalis fascia and parietal peritoneum. It also describes the superficial vessels and nerves, venous anastomoses around the umbilicus including caput medusae, and clinical points on hernias and surgical incisions such as McBurney's.

In this note

  1. VENTRO - LATERAL ABDOMINAL WALL
  2. Boundaries :
  3. Surface Anatomy:
  4. Blood vessels & Nerves:
  5. Venous Anastmoses:
  6. Clinical Significance :

Boundaries :

Sup: Inf. margin of costal arches + xiphoid process,

Laterally: Post. axillary lines

Inf.: inguinal canal, iliac crests + pubic symphysis.

Surface Anatomy:

  1. 1 Skin and subcutaneous tissue
  2. 1.1 Fatty layer (panniculus adiposus) – contains subcutaneous veins
  3. 1.2 Fascia of Camper – composed of fine fibrous fibers within subcutaneous fat
  4. 2 Fascia of Scarpa (fascia cutanea abdominis)
  • – a membranous layer of subcutaneous tissue (stratum membranosum telae subcutaneae)
  • – separates the subcutaneous and deep fatty layer
  1. 3 Deep fatty layer – thinner than the superficial fatty layer
  2. 4 Superficial abdominal fascia – the fascia of the external oblique
  3. 5 External oblique
  4. 6 Internal oblique
  5. 7 Transversus abdominis
  6. 8 Transversalis fascia – part of the parietal abdominal fascia
  7. 9 Parietal peritoneum

Superficial fascia

  • * Camper's fascia – consist of fatts,
  • thinner around the linea alba.
  • absent around the umbilicus.
  • Continues with the superficial fascia of the thigh.
  • * Scarp's fascia – membranous layer.
  • fuses inferiorly with the fascia lata of the thigh.
  • In males, it extends onto the dorsum of the penis, forming the fundiform ligament.
  • In females, it extends into the labia majora & connects to the Colle's fascia.
