gomphosis joints

(noun)

Joints of very limited mobility. These are found at the articulation between teeth and the sockets of maxilla or mandible (dental-alveolar joint).

Examples of gomphosis joints in the following topics:

  • Gomphoses

    • A gomphosis is a fibrous joint that binds the teeth to bony sockets in the bones of the maxilla mandible.
    • A gomphosis is a joint that anchors a tooth to its socket.
    • Each tooth has bony protrusions or pegs that latch into the socket with the assistance of the gomphosis.
    • This particular joint is an example of a synarthrosis, a joint with limited to no movement.
    • One disorder that can affect the gomphosis is scurvy, a disease of connective tissue.
  • Functional Classification of Joints

    • This category includes fibrous joints such as suture joints (found in the cranium) and gomphosis joints (found between teeth and sockets of the maxilla and mandible).
    • Most joints in this category include cartilaginous joints such as those found between vertebrae and the pubic symphysis.
    • An example is the elbow joint.
    • Multiaxial – Includes the ball and socket joints.
    • An example is the hip joint.
  • Structural Classification of Joints

    • Joints provide the means for movement.
    • Gomphosis is a type of joint found at the articulation between teeth and the sockets of the maxilla or mandible (dental-alveolar joint).
    • They allow more movement than fibrous joints but less than that of synovial joints.
    • (a) Sutures (b) Syndesmosis  (c) Gomphosis.
    • Image demonstrates a synchondrosis joint with epiphyseal plate (temporary hyaline cartilage joint) indicated (a) and a symphysis joint (b).
  • Fibrous Joints

    • Fibrous joints are also called fixed or immovable joints because they do not move.
    • There are three structural classifications of joints:
    • These joints are also called fixed or immovable joints because they do not move.
    • Fibrous joints have no joint cavity and are connected via fibrous connective tissue.
    • The movement of the root within a gomphosis has a threefold effect.
  • Types of Synovial Joints

    • Anatomical joints may consist of a combination of two or more joint types.
    • The atlanto-axial joint, proximal radioulnar joint, and distal radioulnar joint are examples of pivot joints.
    • Examples include the wrist joint (radiocarpal joint) and the temporomandibular joint.
    • The knee joint is an example of a compound joint/modified hinge joint where different types of joints combine.
    • Collection of Joint Movements (Example): Wave your arm (hinge joint) and hand (condyloid joint) while nodding your head (pivot joint), and giving a thumbs up (saddle joint).

  • Classification of Joints on the Basis of Structure and Function

    • The structural classification divides joints into fibrous, cartilaginous, and synovial joints depending on the material composing the joint and the presence or absence of a cavity in the joint.
    • Synovial joints are the only joints that have a space between the adjoining bones .
    • Synovial joints are capable of the greatest movement of the three structural joint types; however, the more mobile a joint, the weaker the joint.
    • Knees, elbows, and shoulders are examples of synovial joints.
    • Synovial joints are the only joints that have a space or "synovial cavity" in the joint.
  • Synovial Joint Movements

    • A synovial joint, also known as a diarthrosis, is the most common and most movable type of joint in the body of a mammal.
    • Structural and functional differences distinguish synovial joints from cartilaginous joints (synchondroses and symphyses) and fibrous joints (sutures, gomphoses, and syndesmoses).
    • There are six types of synovial joints.
    • The six types of joints include:
    • Saddle joints - permit the same movement as condyloid joints and combine with them to form compound joints
  • Types of Synovial Joints

    • The shape of the joint affects the type of movement permitted by the joint.
    • These joints allow for gliding movements; therefore, the joints are sometimes referred to as gliding joints.
    • Examples of ball-and-socket joints are the shoulder and hip joints .
    • (e) The radiocarpal joint of the wrist is a condyloid joint.
    • The metacarpophalangeal joints in the finger are examples of condyloid joints.
