Patellae is the plural form of the word "patella," which is a Latin term used in anatomy and biology. Patella refers to the kneecap, a small, flat, triangular bone located in the front part of the knee joint. It acts as a protective covering for the knee and plays a vital role in the movement and stability of the leg.
The patella is a sesamoid bone, meaning it develops within a tendon, specifically the quadriceps tendon. Its shape resembles that of a small shield or crescent and is situated between the femur (thigh bone) and the tibia (shin bone). The patellae not only protects the knee joint from external impacts but also provides leverage to the quadriceps muscles, aiding in the extension of the leg and facilitating movements such as walking, running, and jumping.
The patella has a smooth surface covered in cartilage, allowing it to glide smoothly over the corresponding groove at the end of the femur when the knee is flexed or extended. It is connected to the lower leg bones through the patellar tendon, which is thick and strong to withstand the tension generated during physical activities.
In summary, patellae refers to multiple kneecaps found in humans and certain animals. These bony structures form an integral part of the knee joint, protecting it and enhancing the function of leg muscles related to movement and stability.
