A sesamoid bone isa)Palatineb)Patellac)Pterygoidd)PresphenoidCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

This small round bones sesamoid bone commonly found in tendons of the hands, knees and feet.
So answer is patella.

Answer

Sesamoid bones are small more or less rounded masses embedded in certain tendons and usually related to joint surfaces. Their functions probably are to modify pressure, to diminish friction, and occasionally to alter the direction of a muscle pull.

Answer

Sesamoid bones can be found on joints throughout the body, including: In the knee—the patella (within the quadriceps tendon). This is the largest sesamoid bone.

Answer

Patella is the small bone in knee joint between femur and tibia. It is a sesamoid bone developed in the tendon of quadriceps femoris etc

Answer

Sesamoid bones are commonly found on joints.... n one of them is found in patella. So the opt is B.

Answer

A sesamoid bone is the patella.

Explanation:

A sesamoid bone is a type of bone that is embedded within a tendon or muscle. It is named after the sesame seed, as it is small and round in shape, resembling the seed. The patella, commonly known as the kneecap, is the largest and most well-known sesamoid bone in the human body.

Function of the Patella:

The patella plays a crucial role in the functioning of the knee joint. It acts as a fulcrum, increasing the leverage of the quadriceps muscles as they extend the leg. This allows for more efficient movement and helps to protect the knee joint from excessive stress and strain.

Anatomy of the Patella:

The patella is a flat, triangular bone located in front of the knee joint. It is situated within the tendon of the quadriceps muscle and is held in place by ligaments and other soft tissues. The superior surface of the patella is smooth and articulates with the femur, while the inferior surface is rough and attaches to the patellar tendon.

Development of the Patella:

The patella is a unique bone because it does not develop through the process of ossification from a cartilage precursor. Instead, it forms within the tendon of the quadriceps muscle during fetal development. Over time, the patella gradually ossifies and becomes a fully formed bone.

Conclusion:

In summary, a sesamoid bone is a bone that is embedded within a tendon or muscle. The patella, also known as the kneecap, is an example of a sesamoid bone. It plays a crucial role in the functioning of the knee joint, acting as a fulcrum for the quadriceps muscles. Understanding the anatomy and function of the patella is important for studying the musculoskeletal system and its related disorders.
