Study Notes
Urogenital Anatomy: Posterior Abdominal Wall
- Lecture 1: Covers the posterior abdominal wall
- Lecturer: Ms Kerri Keet, Senior Lecturer, Division of Clinical Anatomy, [email protected]
- Location: Room 4021, Level 4, Tygerberg Campus
- Outcomes: Students should be able to name and describe bony components, muscles, and structures of the posterior abdominal wall, including origin, insertion, action, innervation, and blood supply.
Bony Components of the Posterior Abdominal Wall
- Contains five lumbar vertebrae and intervertebral discs
- Structure provides stability and support
- Important for spinal movement and weight distribution
Muscles of the Posterior Abdominal Wall
- Psoas Major & Minor: Located anterior to vertebral bodies. Originates from lumbar vertebrae. Inserts into the lesser trochanter of the femur. Innervated by anterior rami of L1, L2, and L3. Function: Flexes thigh at hip in conjunction with iliacus.
- Iliacus: Originates laterally on iliac fossa. Inserts into lesser trochanter of femur, and is innervated by femoral nerve. Function: Flexes the thigh at the hip joint
- Quadratus Lumborum: Originates from the iliolumbar ligament and iliac crest. Inserts into the transverse processes of L1 through L4 vertebrae inferior aspect of rib 12. Innervated by anterior rami of T12, L1,2,3, and L4. Function: Depresses ribs, stabilizes rib 12 and assists in lateral flexion of the trunk
Structures of the Posterior Abdominal Wall
- Nerves (Lumbar Plexus, Sympathetic nerves): Provides motor and sensory function in the area
- Arteries (abdominal aorta and branches): Deliver oxygenated blood to the region
- Veins (inferior vena cava and tributaries): Drain deoxygenated blood from the area
- Lymphatic vessels and lymph nodes: Drains lymph from the region
- Fascia: Layers of connective tissue supporting the abdominal wall
Diaphragm
- Structure & attachments: The diaphragm is a dome-shaped muscle separating the thoracic and abdominal cavities. It is composed of a central tendon and surrounding muscular sections (sternal, costal, and lumbar).
- Position: Position varies based on breathing, posture, and abdominal viscera position
- Blood supply: Inferior phrenic arteries and veins supply blood to the diaphragm
- Nerve: Phrenic nerves (C3, C4, C5) innervate the diaphragm
-
Openings and vertebral levels:
- Caval opening: Inferior Vena Cava: T8
- Esophageal hiatus: T10
- Aortic hiatus: T12
Retroperitoneal Space and Fascia
- Structures: The space behind the peritoneum lining the posterior abdominal wall includes structures like kidneys, ureters, and abdominal blood vessels.
- Retroperitoneal structures lie behind the peritoneum and supported by connective tissue layers, called fasciae (connective tissues).
- Fasciae named based on the structures (psoas, renal, thoracolumbar)
- Retroperitoneal spaces and membranes surround structures that are located behind the peritoneum
