Patella (noun)

The knee cap, a small bone in the front of the knee that protects the knee joint and helps in movement.

Origin:

Derived from the latin word 'patina', meaning 'dish or platter'.

Examples:

1. The doctor examined the patient's patella and determined that it was not broken, but just badly bruised.
2. Some people are born with patella problems, such as patella dislocation, which can cause pain and discomfort in the knee.
3. Physical therapy can help to strengthen the muscles around the patella and reduce the risk of injury.
4. The patella is an important structure in the knee, and damage to it can greatly impact a person's mobility.
5. The patella is a unique bone, as it is the only bone in the body that is not directly connected to any other bone.
