Final answer:
The anterior superior iliac spine is a bony landmark on the ilium, and it serves as an attachment point for thigh muscles.
Step-by-step explanation:
The anterior superior iliac spine is a rounded, anterior termination of the iliac crest, which can be felt at the anterolateral hip. It serves as an attachment point for muscles of the thigh. The iliac crest itself is a curved, superior margin of the ilium, one of the three regions of the hip bone. The ilium forms the large, fan-like region of the hip bone, and it also has other bony landmarks like the anterior inferior iliac spine.
