Examples of gomphosis joints in the following topics:
-
- 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.
-
- 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.
-
- 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 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.
-
- 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).

- 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.
-
- 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
-
- 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.
