The structures present in the knee joint are 10

The answer is C and D. That's for sure.

1.Articular labrum: an annular fibrocartilage plate, attached to the periphery of the socket, which can increase and deepen the depth of the socket and make the joint more stable. For example, the shoulder joint (ball-and-socket joint) and hip joint (clubbing joint) have articular lips, but the knee joint (uniaxial joint) does not.

2.Femoral head ligament: The femoral head ligament located in the hip joint capsule is a bundle of flat fibers in the joint cavity, mainly starting from the transverse acetabular ligament and ending in the femoral head concave.

3.Articular disc and meniscus: The articular disc is a fibrocartilaginous plate located between two joints; The meniscus is a fibrocartilaginous plate located in the knee joint, so the meniscus can be considered to belong to the articular disc.

There are only 4 parts of the body that have the articular disc tissue: the temporomandibular joint, the sternoclavicular joint, the knee joint, and the radial carpal joint.

4.Biceps tendon: The biceps brachii muscle is located on the anterior side of the upper arm, with a long and short biceps at the upper end.

The long head of the biceps brachii arises from the supraglenoid tuberosity of the scapula with the long head tendon, and the short head rises from the coracoid process of the scapula with the biceps tendon. The long and short biceps converge in the middle of the humerus to form the muscular abdomen, descend to the lower end of the humerus, and integrate the biceps tendon to terminate at the radial tuberosity and the tendon of the forearm.

Clear?? It is recommended that if it is a professional exam, read more books to review and summarize.

c and d, in fact, the meniscus is the joint disc, but in the knee joint this is called the meniscus.

Structural Composition:

The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella, which is the largest and most complex joint in the human body, and belongs to the trochlear joint. The knee joint is composed of tissues such as the femoral condyle, tibial plateau, patella and its surrounding synovium, joint capsule, ligaments, meniscus, and muscles. The lateral condyle is high, limiting patellar dislocation.

The anterior and posterior cruciate ligaments are used to stabilize the knee joint: the anterior cruciate ligament restricts the excessive anterior displacement of the tibia, and the posterior cruciate ligament restricts the excessive posterior movement of the tibia, both of which together limit the hyperextension of the knee joint, the rotation of the tibia, and the lateral movement of the extended.

Movement characteristics: The knee joint is the most complex structure, the largest joint, and the strongest lever force in the whole body. Although it is a flexion joint, its motion is two-dimensional. Although the range of motion is not as wide as that of the shoulder and hip joints, it has a more precise and complex pattern.

Articular structureThe knee joint includes the medial and lateral tibialfemoral joints, which are formed by the lower end of the femur and the upper end of the tibia, and the patellofemoral joint, which is composed of the patella and femoral trochlea.

Enlargement of the lower end of the femur. It is the medial condyle and the lateral condyle, which is the intercondylar fossa, and the transverse diameter of the internal condyle is longer than that of the lateral condyle. The longitudinal diameter (anterior-posterior diameter) is shorter than that of the lateral condyle, and the cartilaginous surface of the medial and medial condyles is associated with the upper end of the tibia, and the cartilaginous surface between the anterior two condyles is associated with the cartilaginous surface behind the patellae.

Which of the following structures make up a knee joint? （）

a.Medial tibial aurisa condyle.

b.Tibia lifts lateral condyle of the parabone.

c.The femur pays homage to the medial condyle.

d.Lateral femoral condyle.

e.Patella. Correct answer: ABCDE

Answer]: C Which boring guide for the test] The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella, which is the largest joint in the human body and the most complex structure of the bend of the body. The patella is connected to the patellar plane of the femur, and the medial and lateral condyles of the femur are opposite the medial and lateral condyles of the tibia.

a.The joint capsule is broad and flaccid.

b.There are many ligaments around the capsule that are reinforced.

c.There is a meniscus inside the joint capsule.

d.There are biceps femoris tendons in the joints.

e.There are cruciate ligaments within the joint capsule.

Correct answer: d
