Which of the following synovial joint types is multiaxial?
Ball and Socket
Synovial: Ball and Socket A ball and socket joint is an articulation between the rounded head of one bone (ball) and the concavity of another (socket). This type of joint is multiaxial: it permits flexion/extension, abduction/adduction, and rotation.
What are multiaxial joints examples?
The shoulder and hip joints are multiaxial joints. They allow the upper or lower limb to move in an anterior-posterior direction and a medial-lateral direction. In addition, the limb can also be rotated around its long axis.
What is the type of synovial joint working at the ankle?
Overview. The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion). However, when the range of motion of the ankle and subtalar joints (talocalcaneal and talocalcaneonavicular) is taken together, the complex functions as a universal joint (see the image below).
Are synovial joints multiaxial?
Synovial joints can also be classified as nonaxial, monoaxial, biaxial, and multiaxial. The various movements permitted by synovial joints are abduction, adduction, extension, flexion, and rotation.
What are the two types of joints that involve the sternum?
Sternocostal joints
| Type | Sternochondral joint 1: Primary cartilaginous joint (synchondrosis) Sternochondral joints 2-7: Synovial planar joints, nonaxial, uniplanar |
|---|---|
| Articular surfaces | Sternal ends of costal cartilages of the true ribs, costal notches on sternum |
Which structure attaches a muscle to bone and helps stabilize a synovial joint?
Tendons connect muscle to bone and move the bones or structures to which they are attached. A bursa (plural bursae) is a small, fluid-filled sac lined by synovial membrane with an inner capillary layer of fluid (synovial fluid) with the consistency of raw egg white.
What is multiaxial joint?
A joint that allows for the several directions of movement is called a multiaxial joint (polyaxial or triaxial joint). This type of diarthrotic joint allows for movement along three axes (Figure 3). The shoulder and hip joints are multiaxial joints.
What is meant by multiaxial joint?
[ mŭl′tē-ăk′sē-əl, -tī- ] n. A joint in which movement occurs in a number of axes.
Which type of fibrous joint connects the tibia and fibula?
syndesmosis
A syndesmosis is a slightly movable fibrous joint in which bones such as the tibia and fibula are joined together by connective tissue. An example is the distal tibiofibular joint. Injuries to the ankle syndesmosis are commonly known as a “high ankle sprain”.
Which type of synovial joint is multiaxial allowing motion in more than one plane of movement?
Spheroidal (ball and socket) joints are universal joints that permit multiaxial movements. Examples include the hip and shoulder. Ellipsoid joints (oval and socket) are shallower articulations that allow movements in at least two planes.
What is the synovium of the ankle joint?
The ankle joint comprises of strong connective tissue surrounding the joint known as the joint capsule. The joint capsule is lined with specialized tissue known as the synovium (or synovial membrane) which is responsible for secreting lubricating fluid (synovial fluid) into the ankle joint, therefore reducing friction…
What are the articulations of the atlantoaxial joint?
The atlantoaxial joint, between the atlas and axis, consists of three articulations. The paired superior articular processes of the axis articulate with the inferior articular processes of the atlas. These articulating surfaces are relatively flat and oriented horizontally.
What kind of stretches can I do for ankle synovitis?
Hold the stretch position for a minimum of 20 seconds and then repeat with the opposite leg. Leaning Heel-Back Achilles Stretch (1:17) Stand upright while leaning against a wall and place one foot behind the other. Make sure that both toes are facing forward and your heel is on the ground.
What is the function of synovial fluid in the ankle?
The ankle joint comprises of strong connective tissue surrounding the joint known as the joint capsule. The joint capsule is lined with specialized tissue known as the synovium (or synovial membrane) which is responsible for secreting lubricating fluid (synovial fluid) into the ankle joint, therefore reducing friction during ankle movements.
