What connects to ischial spine?

Your ischial tuberosity is the lower part of your pelvis that’s sometimes referred to as your sit bones. It helps to absorb your weight when you sit. However, it can also cause pain when a nearby fluid-filled sac, called the ischial bursa, becomes inflamed and causes ischial bursitis.

What muscles are attached to the pubic bone?

Muscles that insert on the pubis:

  • rectus abdominis muscle (lateral head) just lateral to pubic crest.
  • pyramidalis muscle just below the attachment of rectus abdominis.
  • levator ani muscle (levator prostatae and puborectalis)
  • conjoint tendon at the pecten pubis.

Do men have ischial spines?
