20
Q

Whats the largest foramen in the skeleton + what is it surrounded by?

A

Obturator foramen

Surrounded by ramus + pubis.

21
Q

Define the ramus

A

Where ischium fuses w. pubis.

22

POSTERIORLY w/ sacrum at sacroiliac joint

37
Q

Define the acetabulum notch

A

Deep indentation on the inferior side of the acetabulum.
