Question

identify the bone highlighted and indicated by the arrow.
answers: a - d
a ischium
b coccyx
c ileum
d pubis

Explanation:

The ilium is the largest and uppermost bone of the hip bone (coxal bone). In the image of the pelvic girdle, the highlighted and arrow - indicated part corresponds to the ilium. The ischium is the lower and posterior part of the hip bone, the coccyx is the tailbone (not part of the hip bone itself in the same sense as the coxal bone components), and the pubis is the anterior part of the hip bone.

Answer:

C. Ileum
