What is the functional classification of the Talocrural joint?
The ankle joint, also known as the talocrural joint, is a synovial joint that connects the bones of the leg, the fibula and tibia, with the talus of the foot. It is a complex hinge joint composed of two articulations.
What bones articulate at the Talocrural joint and what movements are permitted at this joint?
The talus articulates inferiorly with the calcaneus and anteriorly with the navicular. The upper surface, called the trochlear surface, is somewhat cylindrical and allows for dorsiflexion and plantarflexion of the ankle.
Which of the following joints would be an example of a symphysis?
The hip bones, connected by the pubic symphysis, and the vertebrae, connected by intervertebral discs, are two examples of symphyses.
What functional type of articulation is a synovial joint?
A synovial joint, also known as a diarthrosis, is the most common and most movable type of joint in a mammal’s body. Diarthroses are freely movable articulations. In these joints, the contiguous bony surfaces are covered with articular cartilage and connected by ligaments lined by synovial membrane.
What is the function of the ankle joint?
The ankle joint allows up-and-down movement of the foot. The subtalar joint sits below the ankle joint, and allows side-to-side motion of the foot.
What are the two articulating bones in the Femoropatellar joint?
The femoropatellar joint is between the patella and distal femur. The patella, a sesamoid bone incorporated into the tendon of the quadriceps femoris muscle of the anterior thigh, serves to protect this tendon from rubbing against the distal femur during knee movements.
What is the function of symphysis joint?
Symphyses (singular: symphysis) are secondary cartilaginous joints composed of fibrocartilage (and hence also known as fibrocartilaginous joints). They are considered amphiarthroses, meaning that they allow only slight movement and are all found at the skeletal midline.
What are the 3 functional classifications of joints?
Joints can be classified by the type of the tissue present (fibrous, cartilaginous or synovial), or by the degree of movement permitted (synarthrosis, amphiarthrosis or diarthrosis).
What are the classification of synovial joints?
Synovial joints are often further classified by the type of movements they permit. There are six such classifications: hinge (elbow), saddle (carpometacarpal joint), planar (acromioclavicular joint), pivot (atlantoaxial joint), condyloid (metacarpophalangeal joint), and ball and socket (hip joint).
Is the Talocrural joint a hinge joint?
The talocrural joint is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus.
