A fatigue fracture is a small hairline fracture. It is due to constant stress being placed on a bone, rather than one major blow. It may occur after jogging, hiking, standing or even marching. There is usually pain and tenderness at the place where the fracture occurs.

Answer: Periosteum

The outside of bone consists of two layers of connective tissue. The first outer layer has blood vessels and nerves that nourish the bone. The second layer is the one that attaches the periosteum to the bone itself.

Answer: Acetabulum

The joint between the thighbone and hipbone is called a ball and socket joint. The thighbone fits into the lower pelvis so that the hip can move in many directions. Acetabulum means deep cuplike cavity.

Answer: Epiphyseal plate

Children's bones all have growth plates at the ends of them. This plate is made up of cartilage, where all the necessary growing takes place. When puberty hits, the plates become calcified.

At the top third of the front of the tibia bone is a small area of raised bone. The quadriceps tendon crosses the kneecap and joins onto this area of extra bone. When children play too much sport, this area becomes inflamed and painful. When this happens, Osgood-Schlatter disease is named as the problem.

Answer: Carpals, metacarpals and phalanges

The eight carpal bones are small pebble-like bones that make up the wrist. They are arranged in two layers of four bones. The long thin metacarpal bones are joined to the carpal bones. The phalanges (4 fingers and 1 thumb) are joined to the metacarpal bones via the knuckles of the hand. The phalanges have 3 segments of bones called the proximal, intermediate and distal phalanges.

Answer: Ligaments

Ligaments are made of very strong connective tissue, that contains a lot of fibers. They ensure that the bone to bone connection is strong enough to prevent movement between them.

Answer: All of these

The three types of bone cell work together to repair, grow and keep the shape of bones. The osteoblast is responsible for growth of bone. The osteocytes are mature bone cells which cannot divide. The osteoclast digest bone tissue to make new cells.

Answer: Hamate

The hamate bone is a small hook-shaped bone of the wrist.

Answer: Maxilla

The maxilla is a large bone of the upper jaw and the mandible is a large bone of the lower jaw. They are joined together by a joint called the temporomandibular joint. When certain face muscles contract, they all work together to make chewing food and talking possible.
