Is the temporomandibular joint a synovial joint?
Is the temporomandibular joint a synovial joint?
The temporomandibular joint (TMJ), also known as the mandibular joint, is an ellipsoid variety of the right and left synovial joints forming a bicondylar articulation.
Is temporomandibular synovial?
Now that we’ve seen the mandible, let’s take a look at the joint that enables it to move: the temporomandibular joint. It’s a synovial joint, with articular cartilage on the bone surfaces, and a joint capsule that encloses synovial fluid.
Why temporomandibular joint is synovial joint?
It is a bilateral synovial articulation between the temporal bone of the skull above and the mandible below; it is from these bones that its name is derived. This joint is unique in that it is a bilateral joint that functions as one unit….

What is a synovial joint?
Synovial joints are the most common type of joint in the body (see image 1). The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule. This fluid-filled space is the site at which the articulating surfaces of the bones contact each other.
What kind of synovial joint is the TMJ?
Joint. TMJ is a synovial, condylar and hinge-type joint. The joint involves fibrocartilaginous surfaces and an articular disc which divides the joint into two cavities. These superior and inferior articular cavities are lined by separate superior and inferior synovial membranes.
What bones form the temporomandibular joint?
Top, The temporomandibular joint (TMJ) is formed at the meeting point of the temporal bone, which is part of the cranium (skull), and the lower jaw bone, called the mandible.
What type of synovial joint is temporomandibular?
Joint. TMJ is a synovial, condylar and hinge-type joint. The joint involves fibrocartilaginous surfaces and an articular disc which divides the joint into two cavities. The disc articulates with the mandibular fossa of the temporal bone above and the condyle of the mandible below.
Where are the synovial membranes?
joints
A layer of connective tissue that lines the cavities of joints, tendon sheaths, and bursae (fluid-filled sacs between tendons and bones). The synovial membrane makes synovial fluid, which has a lubricating function.
What are synovial joints examples?
The different types of synovial joints are the ball-and-socket joint (shoulder joint), hinge joint (knee), pivot joint (atlantoaxial joint, between C1 and C2 vertebrae of the neck), condyloid joint (radiocarpal joint of the wrist), saddle joint (first carpometacarpal joint, between the trapezium carpal bone and the …
What type of synovial joint is the elbow?
hinge joints
The elbow and knee joints are both hinge joints. A hinge joint is a type of synovial joint that works like the hinge on a door, allowing bending and straightening only.
What kind of synovial joint is found between the skull and Atlas?
atlanto-occipital joint
The atlanto-occipital joint (Capsula articularis atlantooccipitalis) is an articulation between the atlas bone and the occipital bone. It consists of a pair of condyloid joints. It is a synovial joint….
