Describe the Structure of the Knee Joint

It is the weight-bearing component of the knee joint. Knee joint anatomy involves looking at each of the different structures in and around the knee.

At the junction of the knee the large femur bone of the thigh connects to both the tibia and fibula of the leg as well as to the patella or knee cap.

. The knee joint is a synovial joint this means it contains a fluid that lubricates it. Tibiofemoral medial and lateral condyles of the femur articulate with the tibial condyles. The joint surfaces are lined with hyaline cartilage and are enclosed within a single joint cavity.

It consists of bones meniscus ligaments and tendons. By definition a joint is a point where two bones meet to provide a framework that permits movement. The knee joint is the largest and one of the most complex joints in the human body.

The tibio-femoral is the joint where the tibia meets the femur The patellofemoral joint where the kneecap or patella meets the femur There are two menisci or meniscus solitary in the knee. The knee is formed by the articulation of the femur bone in the thigh with the tibia in the lower leg. The thigh bone the shin bone and the kneecap articulate through tibiofemoral and.

Primarily composed of cancellous spongy bone each epiphysis typically articulates with another bone forming a joint and helps transmit weight-bearing forces across regions of the body. The role of joints and connective tissue Connective tissues consist. The inner layer or intima consists of a sheet of cells thinner than a piece of paper.

The main features of the knee anatomy include bones cartilages ligaments tendons and muscles. These are the main restaining retinacular structures of the lateral knee. The knee is the joint where the bones of the lower and upper legs meet.

Articular Capsule of the Knee Joint. It holds together the articulating bones and supports the underlying synovium. An inside look at the structure of the knee.

A joint is a place where two or more bones meet and is also called an articulation. The knee consists of three bones. Bones are attached to one another by tissues called ligaments.

The knee Forms Two Main Joints. The lateral knee has two distinct functional layers. It consists of two layers.

These two joints are aligned in such a way that they work together to form a modified type of hinge joint. Knee joint Hinge joint.

Femur the upper leg bone or thigh bone. The largest joint in the body the knee moves like a hinge allowing you to sit squat walk or jump. Overview of the knee joint anterior and posterior views Anatomy edit edit source Articulating Surfaces edit edit source.

In the knee joint the femur articulates with the tibia and the patella. The knee is a hinge joint that is responsible for weight-bearing and movement. The knee can bend flex and rotate which allows a person to stand up walk their dog play sports with friends and sit down.

There are various muscles that control movement ligaments that give stability special cartilage to absorb pressure and various other structures to ensure smooth pain-free movement. Articular cartilage lines the articular surface of each epiphysis acting as a shock absorber between joints. The knee is designed to fulfill a number of functions.

The outer layer consists of superficial and deep retinacular fibers iliotibial band lateral collateral biceps tendon and fabellofibular ligament. Fibrous layer outer consists of white fibrous tissue known the capsular ligament. The knee is a type of synovial hinge joint.

The knee joint which actually consists of several different connection between four bones happens to be the biggest synovial joint in the human body. The outer layer or subintima can be fibrous fatty or loosely areolar. The morphology of synovial membranes may vary but it often consists of two layers.

Joints can be classified based on structure and function. It is constructed by 4 bones and an extensive network of ligaments and muscles. Allows bending flexion and straightening extension.

The knee is an amazing joint. The knee joint consists of two articulations tibiofemoral and patellofemoral. The joints help us to rotate our shoulder bend our knees and elbows swivel our neck and more.

The knee joint is one of the largest and most complex joints in the body. Knee joint is a bicondylar synovial joint between the femur and the tibia allows flexion extension and some medial and lateral rotation of the leg. A patella or knee cap covers the front of the joint.

The articular capsule surrounds the joint and is continuous with the periosteum of articulating bones. A synovium surrounding the knee joint produces synovial fluid that nourishes protects and supports the joint. Articulating bones are femur and tibia the patella is not classed as part of the joint nor is the fibula.
