Final answer:
The prefix 'post' means a) 'after'. The ilium forms the superior part of the hip bone, and the ischial spine is located between the inferior pubic ramus and ischial ramus.
Step-by-step explanation:
The prefix "post" means after. In biology, this prefix is often used to describe something that occurs after a particular event or time. For example, posterior (or dorsal) refers to the back or the direction toward the back of the body, as in "The popliteus is posterior to the patella."
Addressing the student's anatomy question: The component that forms the superior part of the hip bone is the ilium. The ischial spine, mentioned in another question, is found between the inferior pubic ramus and ischial ramus.
