Orientation

Membranes in the Ventral Body Cavity

• Serous Membrane or Serosa– Double layered

membrane that covers the walls of the ventral body cavity and outer surface of the organs

– Parietal serosa and visceral serosa

Membranes in the Ventral Body Cavity

• Parietal serosa– The outer layer of the

serous membrane that lines the cavity walls

Membranes in the Ventral Body Cavity

• Visceral Serosa– The inner layer of the

serosa that covers the organs of the ventral body cavity

Membranes in the Ventral Body Cavity

• Serous fluid– Separates the serous

membrane– Thin layer of lubricating

fluid

Regions

• Umbilical Region– Centermost region– Surrounding the navel

Regions

• Epigastric Region– Superior to the umbilical

region– Epi = upon, above– Gastri = belly

Regions• Hypogastric (pubic)

Region– Located below the

umbilical region– Hypo = below

Regions

• Right and Left Iliac (Inguinal) Regions– Located lateral to the

hypogastric region – Iliac = superior part of

the hip bone

Regions

• Right and Left Hypochondriac Region– Flank the epigastric

region laterally– Chondro = cartilage

Quadrants

• Right Lower Quadrant– RLQ

Quadrants

• Left Upper Quadrant– LUQ

Quadrants

• Left Lower Quadrant– LLQ
