Study Notes
Pelvis Anatomy
- The pelvis is a region enclosed by pelvic bones and the lower spine.
- It's divided into two parts: the false (greater) pelvis (part of the abdominal cavity) and the true (lesser) pelvis (containing the pelvic cavity).
- The pelvic cavity continuous with the abdominal cavity above.
- The pelvic inlet is completely surrounded by bone.
- The pelvic floor separates the pelvic cavity from the perineum.
- The perineum, situated below the pelvic floor, is bordered by the pelvic outlet.
- It contains openings for the digestive and urinary systems, reproductive tract, and external genitalia.
Pelvic Bones
- The pelvis's bony structure includes two pelvic bones, the sacrum, and the coccyx.
- The sacrum connects to the fifth lumbar vertebra (L5) at the lumbosacral joint.
- Pelvic bones connect posteriorly to the sacrum (sacroiliac joints) and anteriorly to each other (pubic symphysis).
- Each pelvic bone is somewhat irregular and has two sections.
- The upper section, above the oblique line, forms the lateral wall of the false pelvis.
- The lower section, below the oblique line, forms the lateral wall of the true pelvis.
- The linea terminalis, the lower two-thirds of the oblique line, forms part of the pelvic inlet.
- Each pelvic bone contains the acetabulum, a socket that forms the hip joint with the femur's head.
- Below the acetabulum is the obturator foramen, mostly covered by a membrane.
- The obturator canal, a small opening through the membrane, connects the lower limb and pelvic cavity.
- The posterior margin of the pelvic bone comprises the greater sciatic notch, lesser sciatic notch, and ischial tuberosity.
- The anterior margin includes the anterior superior iliac spine, anterior inferior iliac spine, and pubic tubercle.
