the skeletal system

1. These are the bones in the face and vertebral column. They gave the body protection and shape. Examples are: mandible, cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, coccyx and clavicle (9, 5)
6. a cell which secretes the substance of bone. (10)
7. a large multinucleate bone cell which absorbs bone tissue during growth and healing. (11)
10. Sesamoid bones are found in locations where a tendon passes over a joint. They act to protect the tendon and to increase its mechanical effect sesamoid bone holds the tendon slightly farther away from the centre of the joint and increases the movemen (8, 5)

2. abnormal lateral curvature of the spine. (9)
3. These are the large bones in our legs and arms. They are used in the main movements of the body. Examples are: femur, humorous (4, 5)
4. These are the small bones at the joints of our hands and feet, allowing fine movements. Examples are: carpals, meta-carpals, tarsals, meta-tarsals and phalanges (5, 5)
5. These are the bones of the skull, shoulder girdle, ribs and pelvic girdle. They protect the vital organs of the body. Large muscles can be attached to the flat bones. Examples are: cranium, scapula, ribs and pelvis (4, 5)
8. keeps us balanced and distributes the weight across our skeleton (6, 6)
9. excessive outward curvature of the spine, causing hunching of the back. (8)
