Sesamoid bones are also found occasionally at the metacarpophalangeal joints of the middle and ring fingers, at the interphalangeal joint of the thumb and at the distal interphalangeal joint of the index finger.
In the lower extremity the largest sesamoid bone of the joints is the patella, developed in the tendon of the Quadriceps femoris.
Patella
The patella, also known as the kneecap, is a sesamoid bone. Sesamoid bones are bones that are embedded within tendons and provide protection and mechanical advantage to that tendon. The patella is located within the quadriceps tendon and acts as a fulcrum to increase the leverage of the quadriceps muscles during knee extension.
The patella, also known as the kneecap, is a sesamoid bone. This means it is a small, oval-shaped bone embedded within a tendon. Its function is to protect the knee joint and aid in the action of the quadriceps muscle.
The quadriceps group contains the patella, a large sesamoid bone, within its insertion tendon. The patella enhances the mechanical advantage of the quadriceps muscles by increasing the angle of pull and providing protection to the knee joint during movements.
The quadriceps muscle goes over the patella. The patella is encased in the quadriceps tendon. This tendon inserts on the tibia at the tibial tuberosity. Other muscles from the thigh have tendons which go underneath the patella.
The patella bone is classified as a sesamoid bone, which is a type of irregular bone. Sesamoid bones form within tendons where there is high friction and stress, such as the patella within the quadriceps tendon.
a sesamoid bone
A sesamoid is a small bone embedded within a tendon or muscle, typically found where tendons pass over joints. They help to reduce friction and provide leverage for muscles, aiding in movement. The patella (kneecap) is the largest sesamoid bone in the body.
The insertion tendon that contains a large sesamoid bone is the patella. Some people refer to the patella as the knee cap.
sesamoid bone
A sesamoid bone. This type of bone is found embedded within a tendon or a muscle, typically where it passes over a joint, to protect the tendon from excessive wear and pressure. An example of a sesamoid bone is the patella, embedded within the patellar tendon.
Patella is the sesamoid bone, which has developed in the patellar tendon. This tendon is attached to the tuberosity on the upper and anterior part of tibia bone.
