Is the tibial tuberosity an articular surface?
Inferior and lateral to it is the articular facet for the head of the fibula where the tibia and fibula articulate via the superior/proximal tibiofibular joint. At the anterior surface of the proximal end is the tibial tuberosity.
What connects to the tibial tuberosity?
Structure. The tuberosity of the tibia gives attachment to the patellar ligament, which attaches to the patella from where the suprapatellar ligament forms the distal tendon of the quadriceps femoris muscles. The quadriceps muscles consist of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius …
What structure inserts on the tibial tuberosity?
The quadriceps femoris is a four-headed muscle that inserts onto the tibial tuberosity. It extends the knee, and one head (rectus femoris) flexes the hip. The patella is a sesamoid bone that lies within the quadriceps tendon.
What is the tibial tuberosity made of?
The proximal tibia has two ossification centers, the proximal tibial epiphysis and the tibial tuberosity, which are separated by a cartilage bridge (see the image below). Before ossification, the tibial tuberosity is composed of fibrocartilage that has good tensile strength.
What is the tibial tuberosity of the tibia?
The tibial tuberosity is the bump on the top of the tibia (shinbone) where the patellar tendon connects. Tendons connect muscles to bones. The patellar tendon stretches over the top of the patella (kneecap). The patellar tendon connects the large quadriceps muscle on the front of the thigh to the tibial tuberosity.
Where is the tibial tuberosity and what does it serve as?
Description: The tibial tubercle is the secondary ossification center of the proximal tibia. The primary ossification center is the tibial epiphysis, and the tibial tubercle extends distally from the anterior aspect of the proximal epiphysis and serves as the point of attachment of the patellar tendon.
What structure attaches the patella to the tibial tuberosity?
The patellar ligament envelopes the inferior third of the patella and attaches the bone to the tibial tuberosity.
What is tuberosity of the tibia?
The tibial tuberosity is the bump on the top of the tibia (shinbone) where the patellar tendon connects. Tendons connect muscles to bones. The patellar tendon stretches over the top of the patella (kneecap).
What is a tuberosity?
Tuberosity – A moderate prominence where muscles and connective tissues attach. Its function is similar to that of a trochanter. Examples include the tibial tuberosity, deltoid tuberosity, and ischial tuberosity. Tubercle – A small, rounded prominence where connective tissues attach.
Where is the tuberosity?
Which of the following attaches to the anterior surface of the tibia?
The proximal anterior surface of the tibia is prominent, forming the tibial tuberosity, to which is attached the patellar ligament. The proximal end of the fibula articulates with the tibia at a facet beneath the overhang of the lateral tibial condyle.
What is the tibial tuberosity?
The tibial tuberosity is a large, quadrangular process found at the proximal and cranial aspect of the tibia.
Where is the tibial nerve located in the popliteal area?
Proximally, the tibial nerve is the most superficial structure within the popliteal fossa. This relatively posterior position protects the nerve in most surgical approaches involving the knee.
What is the popliteal artery?
The popliteal artery is a continuation of the femoral artery, a large artery that enters the lower extremity through the femoral sheath after passing under the inferior margin of the inguinal ligament. This major artery of the lower extremity gives off a deep femoral branch proximally in the anterior thigh, then continues its course inferiorly.
What is the popliteal fossa?
The popliteal fossa is the space on the posterior side of the knee joint created by the border of four muscle bellies. Superomedially is the semimembranosus muscle, superolaterally is the biceps femoris muscle, and inferomedially and inferolaterally are the medial and lateral heads of the gastrocnemius, respectively.
