- 10Long bones have enlarged ends called __________ and an elongated shaft called the _____________.epiphyses; diaphysis
- 11Sutural bones are strictly speakingflat bones

- 20What is the periosteum?Periosteum is the name given to the outer connective tissue that covers the entire length of the bone. Periosteum fibres and those of ligaments and tendons unite to connect bone to bone or muscle to bone.
- 21Epiphyseal plates are thegrowth plates that occurs at various locations at the epiphyses of long bones
- 22What is the cortex?It is the exterior layer of bones. It is dense and smooth and of varying thickness depending on the type of the bone, the interior core consists of networks of fibres (Trabeculae) that mesh with blood vessels and the bone marrow.
