The patella is found in many tetrapods, such as mice, cats, birds and dogs, but not in whales, or most reptiles. In humans, the patella is the largest sesamoid bone (i.e., embedded within a tendon or a muscle) in the body. Babies are born with a patella of soft cartilage which begins to ossify into bone at about four years of age.
Leg bones are the bones found in the leg. These can include the following: Femur – The bone in the thigh. Patella – The knee cap; Tibia – The shin bone, the larger of the two leg bones located below the knee cap; Fibula – The smaller of the two leg bones located below the patella
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
The patellar tendon is a strong, flat ligament, which originates on the apex of the patella distally and adjoining margins of the patella and the rough depression on its posterior surface; below, it inserts on the tuberosity of the tibia; its superficial fibers are continuous over the front of the patella with those of the tendon of the quadriceps femoris.
The major bones of the leg are the femur (thigh bone), tibia (shin bone), and adjacent fibula, and these are all long bones. The patella (kneecap) is the sesamoid bone in front of the knee . Most of the leg skeleton has bony prominences and margins that can be palpated and some serve as anatomical landmarks that define the extent of the leg.
Above, the reflection appears lifted from the bone by underlying periosteal connective tissue. [2] In a standing posture, the suprapatellar bursa is seemingly redundant. It is however also referred to as the suprapatellar synovial recess as it gradually unfolds as the knee is flexed; to open up completely when the knee is flexed 130 degrees. [ 3 ]
In anatomy, a sesamoid bone (/ ˈ s ɛ s əm ɔɪ d /) [1] [2] is a bone embedded within a tendon or a muscle. [3] 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, [4] or can be present as a normal variant. The patella is the
Sesamoid bones vary in number and placement from person to person but are typically found in tendons associated with the feet, hands, and knees. The only type of sesamoid bone that is common to everybody is the kneecap (patella, pl. patellae) which is also the largest of the sesamoid bones. [1]
