Idea for the Q&A below: The relevant sentence in the passage is: The ends of epiphyses are covered with hyaline cartilage ("articular cartilage").

Q: The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility. They grow primarily by elongation of the diaphysis, with an epiphysis at each end of the growing bone. The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland.

What is the connective tissue that covers the epiphyses of a long bone?
A: hyaline cartilage ( `` articular cartilage '' )
