What does the Perineal Muscle do?
|
Reinforces the floor of the front part of the pelvis, essential the urogenital triangle

|
What is the Lacunar Ligment and where is located?
|
It attaches to the pectin pubis and as the inguinal ligament reaches the pubic tubercle it reflects backward and lateralward to attach to the Pectin Pubis. This posterior projection of the inguinal ligament is called the lacunar ligament.
