Ligaments of the Pelvis Flashcards
Q: What is the main function of the anterior sacroiliac ligament?
A: The anterior sacroiliac ligament stabilizes the sacroiliac joint by connecting the sacrum to the ilium and helping to support the weight of the upper body.
Q: Where is the posterior sacroiliac ligament located?
A: The posterior sacroiliac ligament runs from the sacrum to the ilium at the posterior aspect of the sacroiliac joint, contributing to its stability.
Q: What are the functions of the sacrotuberous ligament?
A: The sacrotuberous ligament extends from the sacrum to the ischial tuberosity, providing stability to the sacroiliac joint and limiting the movement of the sacrum.
Q: Describe the location and function of the sacrospinous ligament.
A: The sacrospinous ligament runs from the sacrum and coccyx to the ischial spine. It helps stabilize the sacroiliac joint and limits sacral movement.
Q: How does the pubic symphysis contribute to pelvic stability?
A: The pubic symphysis, though not a ligament but a cartilage joint, provides stability to the pelvis by connecting the left and right pubic bones.
Q: What is the role of the iliolumbar ligament?
A: The iliolumbar ligament connects the lumbar vertebrae to the ilium, stabilizing the lumbosacral joint and supporting the pelvis.
