Ontogenesis coelom • 2-nd month. The source - splanchnopleura • Ventral mesentery • Dorsal mesentery • Major and minor omentums
Abdominal cavity Walls • Fascias • Spaces
Peritoneum Parietal layer Visceral layer
Abdominal cavity- • this space of the body, located lower than the diaphragm is filled with internal organs: predominantly digestive and urogenital systems
Walls of the abdominal cavity Walls of the peritoneal cavity • Superior-diaphragma • Anterolateral –abdominal muscles • Posterior – vertebral column and posterior abdominal wall • Inferior – perineum
Functions of the peritoneum • Fixation of internal organs • ligaments,mesentery, omentum • Motions of internal organs • Isolation of internal organs • Reflex area • Trophic • Protection • Regeneration • Reconstructive surgery
Hysterosalpingogram • Radiograph of the uterus and uterine tubesafter injection of radiocontrast material into the uterus through uterine ostium
LIGAMENTS PRIMARY SECONDARY
Division of the peritoneal cavity • Upper storey • Middle storey • Lower storey
Upper storey • above - diaphragm; • anteriorly - parietal peritoneum of anterior abdominal wall; • below – colon transversum and its mesentery • posteriorly - posterior abdominal wall;
Upper storey • Bursa hepatica • Bursa pregastrica • Bursa • omentalis • - Foramen epiploicum
Bursa hepatica • Above – diaphragm • Left side – lig. falciforme • Anteriorly - parietal peritoneum of anterior wall • Behind - right kidney, adrenal gland
BURSA PREGASTRICA • Above – diaphragm • Anteriorly- parietal peritoneum of anterior wall • Right side - lig. falciforme • Behind – stomach • Left side – spleen, its ligaments
BURSA OMENTALIS • Above - caudate lobe of the liver • Anteriorly – lesser omentum, the posterior wall of the stomach • Behind- parietal peritoneum • Below - mesentery of the transverse colon • Left side -ligaments of the spleen
FORAMEN EPIPLOICUM • Above - caudate lobe of the liver • Anteriorly - lig. hepatoduodenalis • Below – pars superior duodeni • Behind- parietal peritoneum
