What are the three types of Joints?
Fibrous Joints, Cartilaginous joints and Synovial Joints
What is a Synarthosis Joint?
A joint which is immovable.
What is a Amphiarthrosis?
A joint which is slightly moveable.
What is a Diarthrosis Joint?
A joint which is freely moveable?
What are examples of Fibrous Joints?
Sutures, Gomphoses, and Syndesmoses.
Where are sutures found?
Between flat bones and skull.
Where are gomphoses found?
Where teeth articulate with their sockets in upper or lower teeth.
What is a syndesmoses?
Bones held by interosseous membrane.
What type of tissue are fibrous joints connected by?
Fibrous tissue.
What are examples of a Cartilaginous joint?
Synchondroses and Symphyses.
What is the synchondroses?
Joint between diaphysis and epiphysis of a growing long bone.
What is an example of a Symphyses?
The Pubis symphysis and intervertebral disc.
What tissue are Cartilaginous joints connected by?
Cartilage; fibrocartilage and hyaline cartilage.
What are synovial joints?
Articular surfaces within the joint capsule.
What are the seven types of synovial joints?
Hinge, Pivot, Ellipsoid, Ball and Socket, Plane, Saddle, Condyloid
What movements can hinge joints carry out?
What is an example of a hinge joint?
Flexion and Extension.
E.g Humero-ulnar joint.
What movements do Pivot joints perform?
What is an example of a pivot joint?
Rotation.
E.g Radio-ulnar joint.
What movements do Ellipsoid joints perform?
What is an example of an Ellipsoid joint?
Ellipsoid joints are bi-planer thus they can perform Flexion / Extension and Abduction / Adduction.
E.g Radio-carpal joint.
What movements do Ball-and-socket joints perform?
What is an example of a Ball-and socket joint?
Ball-and-socket joints are tri-planer thus they can perform; Flexion/Extension, Abduction/Adduction and Rotation.
E.g Coxofemoral Joint
What movements do Plane joints perform?
What is an example of a plant joint?
Rotation and Translation (sliding).
E.g Intercarpal and Intertarsal joint.
What movements do Saddle joints perform?
What is an example of a saddle joint?
saddle joints are bi-planar thus they can perform; Flexion/Extension and Abduction/Adduction.
E.g Sternoclavicular joint
What movements do Condyloid joints perform?
What is an example of a Condyloid joint?
They can perform a combination of
Flexion/Extension and Abduction/Adduction
Or
Flexion/Extension an Axial rotation.
E.g Tibiofemoral joint.
What are some characteristics of Fibrous Joints?
Fibrous Joints are:
- Stabilized by dense C.T.
- Found where optimal stability is required.
- Designed to transfer force from bone to bone.
- Held together by ligaments.
What are some characteristics of Cartilaginous joints?
Cartilaginous joints are:
- Stabilized by forms of fibrous or hyaline cartilage.
- Found in midline, as well as Epiphyseal plates.
- Designed to allow more movement compared to fibrous joints.
- Meant to transfer force from bone to bone.
- Located where articulating bone is composed of cartilage.
