Fibrous Joints: Synarthroses ���Sutures ���
The calvaria or brain case is made up of the frontal, parietal, temporal and occipital bones. The joints between these bones are called the sutures.

Telemark Skiing• The combination of torsional
stress and valgus force (distal segment deviates laterally) on the knee results in the common MCL/ACL injury shown in the animated sequence here on the right.
• This injury is commonly found when the skier catches the inner edge of a lightly weighted or non-weighted ski.
• This can occur when the uphill ski, early in the initiation of a turn, in not weighted properly or is flat on the snow instead of being used to carve the early part of the turn.
Tissue-engineered scaffolding may help the body repair weakened knees and joints.

• In only two weeks, cartilage—one of the most difficult tissues to repair—was regrown in a rabbit knee joint. The newly restored cartilage, stained dark purple on the right, was rebuilt using a new biomaterial that fosters cartilage growth. With further study, this biomaterial may one day help to repair cartilage damage due to injury.
