Study Notes
Bony Pelvis
- The main function of the bony pelvis is to support the spine, protect the internal organs, and serve as an attachment site for muscles.
- The back wall of the bony pelvis is formed by the sacrum and the two auricular surfaces of the hip bones.
- The two hip bones articulate with each other at the symphysis pubis.
- In the correct orientation of the bony pelvis relative to the trunk, the front of the symphysis pubis and the anterior superior iliac spines should lie in the same horizontal plane.
- The pelvic brim is formed posteriorly by the sacral promontory.
- The sacral surface faces upward and backward in the anatomic position.
- The pelvic cavity forms part of the abdominal cavity and supports the abdominal contents.
- The pelvic cavity is bounded by the lumbar vertebrae, the iliac fossae, iliacus muscle, and the lower part of the anterior abdominal wall.
- The birth canal is the bony canal through which the child passes during birth.
- The boundaries behind the pelvic inlet are formed by the sacral promontory, the alae of the sacrum, and the posterior superior iliac spines.
- The perineum is bounded posteriorly by the coccyx, laterally by the ischial tuberosities, and anteriorly by the pubic arch.
- The sacrospinous and sacrotuberous ligaments divide the sciatic notches into greater and lesser sciatic foramina.
- The coccyx forms part of the perimeter of the pelvic outlet and makes it diamond-shaped.
- The pelvis has an inlet, an outlet, and a cavity.
- The pelvic inlet is bounded by the symphysis pubis, the iliopectineal lines, and the sacral promontory.
- The pelvic cavity forms part of the abdominal cavity and supports the gravid uterus.
