MICROANATOMY

Detailed explanation-1: -The patella is a sesamoid bone located in the major extensor tendon of the knee joint, in the hindlimb of many tetrapods. Although numerous aspects of knee morphology are ancient and conserved among most tetrapods, the evolutionary occurrence of an ossified patella is highly variable.

Detailed explanation-2: -Its name is derived from the Greek word for ‘sesame seed’, indicating the small size of most sesamoids. Often, these bones form in response to strain, or can be present as a normal variant. The patella is the largest sesamoid bone in the body.

Detailed explanation-3: -The patella, also known as the kneecap, is a flat, rounded triangular bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint.

Detailed explanation-4: -The patella, commonly referred to as the kneecap, is an example of a sesamoid bone.

Detailed explanation-5: -The patella is the largest sesamoid bone in the human body and is located anterior to knee joint within the tendon of the quadriceps femoris muscle, providing an attachment point for both the quadriceps tendon and the patellar ligament.
