Final answer:
The palpable hip bone projections in the front of the body are the anterior superior iliac spines and the pubic tubercles, which are parts of the ilium and pubis regions of the hip bone, respectively.
Step-by-step explanation:
The palpable hip bone projections in the front of the body are known as the anterior superior iliac spines and the pubic tubercles. These projections are part of the hip bone, which consists of three regions: the ilium, ischium, and pubis. The pubis forms the anterior portion of the hip bone. On the pubic body, which is the enlarged medial portion of the pubis, there is a small bump called the pubic tubercle. The anterior superior iliac spines are located at one end of the iliac crest, which is the superior margin of the ilium. These bony landmarks are used as guides in various medical and athletic practices.
