c) anterior superior iliac spine (asis)
d) ischial spine

1. the pubic symphysis is a joint between:

a) the two hip bones anteriorly
b) the hip bone and sacrum
c) the hip bone and femur
d) ilium and ischium

1. the obturator foramen is largely covered by a membrane and is formed by the:

a) ilium and ischium
b) ischium and pubis
c) ilium and pubis

Explanation:

Question 5

The large sciatic notch is located between the ischial spine and ischial tuberosity. ASIS and PSIS are related to iliac spines, pubic tubercle and iliac crest are different structures, and greater/lesser trochanters are on the femur. So option b is correct.

The anterior superior iliac spine (ASIS) marks the anterior limit of the iliac crest. PSIS is posterior, AIIS is inferior, and ischial spine is not related to iliac crest's anterior limit. So option c is correct.

The pubic symphysis is a joint between the two hip bones anteriorly. The hip - sacrum joint is sacroiliac, hip - femur is hip joint, and ilium - ischium are parts of hip bone. So option a is correct.

Answer:

b) Ischial spine and ischial tuberosity
