Answer 12

pubic arch

Question 13

located more easily when you do hip flexion. crease by your groin. goes from ASIS to pubis and helps with flexibility and provides the lower border for your abdomen. also serves as a major source of muscular attachments

Question 30

primary functional role of the patella

Answer 30

knee extension
