What are the functions of tubular, spongy, flat, and mixed bones?

The spongy bones are located where greater strength and high mobility are needed at the same time, these include the patella and the bones of the wrist. Flat, or wide, bones (scapula, pelvic bone, bones of the brain of the skull) form the walls of the cavities: chest, abdominal, skull – and perform the functions of support and protection. Mixed bones (vertebrae, bones of the base of the skull, etc.) consist of several parts having a different structure and shape. They also serve as support and protection.
