- The temporomandibular joint is the joint of the jaw and is frequently referred to as TMJ. The TMJ is a bilateral synovial articulation between the mandible and temporal bone.The name of the joint is derived from the two bones which form the joint: the upper temporal bone which is part of the cranium (skull), and the lower jawbone or mandible.ach TMJ is classed as a ginglymoarthrodial joint since it is both a ginglymus (hinging joint) and an arthrodial (sliding) joint. The condyle of the mandible articulates with the temporal bone in the mandibular fossa. The mandibular fossa is a concave depression in the squamous portion of the temporal bone.

Gliding Joint Gliding Joint A gliding joint, also known as a plane joint or planar joint, is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. Gliding joints allow the bones to glide past one another in any direction along the plane of the joint — up and down, left and right, and diagonally. Slight rotations can also occur at these joints, but are limited by the shape of the bones and the elasticity of the joint capsule surrounding them.

-  The most common joint type is the diarthrosis of articulating joints, which has a fibrous connective tissue capsule (ligament), continuous with the periosteum of the two bones and which permits a degree of freedom of movement between the two bones.

What is an Immovable Joint? There are several examples of these joints in the human body, including joints between the bones of the skull, joints in the pelvis and joints between the teeth and the mandible, or lower jaw, and the maxilla, or upper jaw.Another name for an immovable joins is a synarthrosis, which simply means immovable.The two types of immovable joints are fibrous joints and cartilaginous joints. Among fibrous joints, there are two types that are considered to be an immovable joint: a suture joint and a gomphoses joint.In a suture joint, the edges of the joined bones fit tightly together much like pieces of a puzzle.here are several examples of these joints in the human body, including joints between the bones of the skull, joints in the pelvis and joints between the teeth and the mandible, or lower jaw, and the maxilla, or upper jaw.

temporomandibular joint one of a pair of joints connecting the mandible of the jaw to the temporal bone of the skull. It is a combined hinge and gliding joint, formed by the anterior parts of the mandibular fossae of the temporal bone, the articular tubercles, the condyles of the mandible, and five ligaments.emporomandibular joint (TMJ) a bicondylar joint formed by the head of the mandible and the mandibular fossa, and the articular tubercle of the temporal bone. See also temporomandibular joint disorder.

fibrous joint facet j's the articulations of the vertebral column. fibrous joint a joint in which the union of bony elements is by continuous intervening fibrous tissue, which makes little motion possible; the three types are suture, syndesmosis, and gomphosis. Called also immovable or synarthrodial joint and synarthrosis.ibrous joint, any one of many slightly movable joints, such as those of the skull segments, in which a fibrous tissue or sometimes a form of cartilage connects the bones. The three kinds of articulation associated with fibrous joints are syndesmosis, sutura, and gomphosis.

gliding joint Called also arthrodial joint and plane joint. hinge joint a synovial joint that allows movement in only one plane, forward and backward. Examples are the elbow and the interphalangeal joints of the fingers. The jaw is primarily a hinge joint but it can also move somewhat from side to side.nee joint the compound joint between the femur, patella, and tibia. pivot joint a synovial joint in which one bone pivots within a bony or an osseoligamentous ring, allowing only rotary movement; an example is the joint between the first and second cervical vertebrae (the atlas and axis).

Joints that unite bones with cartilage are called cartilaginous joints. There are two types of cartilaginous joints: (1) A synchrondosis is an immovable cartilaginous joint. One example is the joint between the first pair of ribs and the sternum.(2) A symphysis consists of a compressable fibrocartilaginous pad that connects two bones. This type of joint allows for some movement.2) The fibrous articulations between the teeth and the mandible or maxilla are called gomphoses and are also immovable. (3) A syndesmosis is a joint in which a ligament connects two bones, allowing for a little movement (amphiarthroses). The distal joint between the tibia and fibula is an example of a syndesmosis.

Background Mandible dislocation is the displacement of the mandibular condyle from the articular groove in the temporal bone. Different types of dislocations can result from traumatic and nontraumatic processes. Most dislocations are managed and reduced in the emergency department with elective follow-up.

ARTICULATIONS (JOINTS) Joints permit varying degrees of movements. Joints are classified into three groups: immovable, slightly movable and freely movable. Arthroscopy is the science concerned with the study of joints or articulations. The articulations of the body are classified into three areas:one forming slightly movable joints. The bones forming slightly movable joints are separated by a layer of cartilage or fibrous connective tissues. Eg. The joints formed by adjacent vertebrae contain intervertebral disc formed of cartilage.

Joint Classification A joint or articulation (or articular surface) is the connection made between bones in the body. They are constructed to allow for different degrees and types of movement. Sutures between the bones of the skull permit very little movement. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis.

ARTICULATIONS (JOINTS) The junction between two bones forms joints or an articulation. Joints permit varying degrees of movements. Joints are classified into three groups: immovable, slightly movable and freely movable. Arthroscopy is the science concerned with the study of joints or articulations. The articulations of the body are classified into three areas: a. Fibrous joints: in these joints, the bones are held together by fibro-cartilagenous tissue and the joints have no cavities. b. Cartilagenous joints: In cartilaginous joints, the bones are held together by cartilage.

Fibrous joints A gomphosis is a fibrous mobile peg-and-socket joint. The roots of the teeth (the pegs) fit into their sockets in the mandible and maxilla and are the only examples of this type of joint. Bundles of collagen fibres pass from the wall of the socket to the root; they are part of the circumdental, or periodontal, membrane.

- Articulation:1. In speech, the production and use of speech sounds. 2. In dentistry, the contact of the occlusal surfaces of the teeth.3. In anatomy, a joint (an area where two bones are attached for the purpose of motion of body parts). An articulation, or joint, is usually formed of fibrous connective tissue and cartilage.

6 Types of Synovial Joints There are six types of synovial joints: gliding, condoloid, saddle, hinge, ball and socket, and pivot joints. Gliding joints allow for smooth movement in several directions along a plane or other smooth surface.The articulation is like two plates sliding across each other. An example would be the carpal bones of the wrist, which form a gliding synovial joint.liding joints allow for smooth movement in several directions along a plane or other smooth surface.
