Which type of joint is most common?

Synovial joints

What is the structure of a joint?

Joints, particularly hinge joints like the elbow and the knee, are complex structures made up of bone, muscles, synovium, cartilage, and ligaments that are designed to bear weight and move the body through space.

What is the function of a joint capsule?

The joint capsule, ligaments, and tendons serve to stabilize the joint, distribute the biomechanical load on the joint and protect the joint by limiting its normal range of motion. The joint capsule is comprised of fibrous connective tissue and inserts into the bone near the articulating surfaces.

What are some examples of hinge joints?

What are hinge joints?

  • elbow.
  • knee.
  • finger joints (interphalangeal joints)
  • toe joints (interphalangeal joints)
  • ankles (tibiotalar joint)

What is a Ginglymus joint?

The hinge, or ginglymus, joint is a modified sellar joint with each mating surface ovoid on its right and left sides. This modification reduces movement to a backward-forward swing like that allowed by the hinge of a box or a door.

Which two bones form a hinge joint?

Anatomy. The elbow joint as a whole is a trochlea arthrosis or ginglymus (hinge) joint, allowing flexion and extension of the humerus over the radius and ulna.

What are the fixed joints?

Joints hold your bones together and allow your rigid skeleton to move. Fixed joints. Some of your joints, like those in your skull, are fixed and don’t allow any movement. The bones in your skull are held together with fibrous connective tissue. Slightly movable joints.

Is the knee joint a pure hinge joint?

The knee joint is not a pure hinge joint but moves with a complex set of translations and rotations. The ligaments of the knee joint include the patellar ligament, the medial and lateral collateral ligaments, and the anterior (ACL) and posterior (PCL) cruciate ligaments.

Why knee joint is considered as hinge joint?

The knee joint is a hinge joint, meaning it allows the leg to extend and bend back and forth with minimal side-to-side motion. It is comprised of bones, cartilage, ligaments, tendons, and other tissues.

What type of joint is the knee joint?

synovial joint

What type of joint is the tibiofemoral joint?

hinge synovial joint

What type of joint is the radiocarpal joint?

condyloid synovial joint

What type of joint is the finger?

The finger joints The joints of the fingers include the metacarpophalangeal joints and the interphalangeal joints. They’re all synovial joints with synovial membranes and fibrous joint capsules.

What is knuckle joint called?

Each metacarpal bone connects to one finger at a joint called the metacarpophalangeal joint or MCP joint. This joint is also commonly referred to as the knuckle joint.

What is a PIP joint in the finger?

Proximal Interphalangeal Joint (PIP Joint) The PIP joint is the first joint of the finger and is located between the first two bones of the finger. The PIP joint can bend and extend the finger. It becomes stiff easily after injury and has very limited side to side motion.
