Answer 2

sacrospinous and sacrotuberous ligaments bound lesser sciatic notch to form lesser sciatic foramen.

Question 3

Answer 6

Internal pudendal A, V, pudendal N (entering ischioanal fossa)

Question 7

Answer 7

OUT of pelvis via infrapiriform foramen;
OVER sacrospinous ligament;
UNDER sacrotuberous ligament;
THROUGH lesser sciatic foramen;
INTO ischioanal fossa.
