GENERAL HISTOLOGY

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: -The most easily found sesamoid bone is the patella, or the kneecap. It is embedded within the patellar tendon that attaches the quadriceps to the tibia.

Detailed explanation-3: -These small, round bones are commonly found in the tendons of the hands, knees, and feet. Sesamoid bones function to protect tendons from stress and wear. The patella, commonly referred to as the kneecap, is an example of a sesamoid bone.
