Question

What is the function of (1) sacrotuberous ligament (2) sacrospinous ligament?

A) (1) Stabilizes the sacroiliac joint; (2) Supports the pelvic viscera
B) (1) Stabilizes the hip joint; (2) Connects sacrum to ischial spine
C) (1) Supports the pelvic viscera; (2) Stabilizes the sacroiliac joint
D) (1) Connects sacrum to coccyx; (2) Supports the hip joint

Answer 1

The sacrotuberous ligament stabilizes the sacroiliac joint, while the sacrospinous ligament supports the pelvic viscera. Both ligaments play roles in supporting and stabilizing the pelvis.

Step-by-step explanation:

The function of the sacrotuberous ligament and sacrospinous ligament is important for maintaining the stability of the pelvis and supporting the sacrum. The sacrotuberous ligament runs from the sacrum to the ischial tuberosity and helps to support and immobilize the sacrum as it carries the weight of the body, thus stabilizing the sacroiliac joint. The sacrospinous ligament extends from the sacrum to the ischial spine and also aids in supporting the sacrum. Additionally, both the sacrospinous and sacrotuberous ligaments contribute to the formation of the greater and lesser sciatic foramina.

The correct answer to the student's question is: A) (1) Stabilizes the sacroiliac joint; (2) Supports the pelvic viscera.
