Question

The ilium, ischium, and pubis fuse into a single bone called the
A) patella.

D) coccyx.

Accepted Answer

The fusion of the ilium, ischium, and pubis forms the coxal bone, also known as the hip bone. The other options are not correct, as the patella is the kneecap, the pelvic girdle is made up of two coxal bones and the sacrum, the pectoral girdle is the shoulder girdle, and the coccyx is formed from the fusion of small vertebrae at the base of the spine.
