Question

Patella, the kneecap is the example of
A) Cartilage gland
B) Replacing bone
C) Sesamoid bone
D) None of the above

Answer 1

Hint: Our skeleton system is composed of several different bones that help in providing strength and structure to the body. Its bones are involved in the protection and movement of the body parts.

Complete Answer:
- It is found in the front portion of the knee joint and it involves the protection of the joint from getting damage.
- It is the largest sesamoid bone of our body that is located within the quadriceps tendons. The bone was involved in the origin of several ossification centers that started its development from age three to six.
- It is a flat, thick, triangular bone with an apex with lateral and medial border. The apex develops to the patellar ligaments that inserts inside the tibial tuberosity of the anterior surface called tibia.
- The middle of the patella has many vascular openings that are used for penetration of arteries that supply to the bone. The stability is maintained by the tension in the medial retinaculum found in the patella bone.
- During the extension of the knee patella bone is involved, as it is found in the anterior surface of the femoral condyles it increases the quadriceps tendon angle that pulls on the tibia this results in the smooth movement of the knee or we call it flexibility and extension.

Hence, the correct answer is ‘C’. Sesamoid bone.

Note: Cartilage is the smooth tissue that has elasticity or we can say a rubber like padding that is found at the end of every long bone to protect the bone in joining with the nerves. It is found in the nose, ears, rib cage, bronchial tubes, and intervertebral discs.
