General Joints Info Flashcards
What are the three ROM classifications a joint can have, and what do each of them mean?
Synarthrosis - Joint cannot move
Amphiarthrosis - Joint can only move a little bit
Diarthrosis - Joint can move
What is a bursa and what is its function?
Fluid-filled sac like cavity, to help with movement of a muscle or tendon over a bony area.
Give examples of synarthrosis joints.
Suture, Gomphosis and Synchondrosis
Give examples of amphiarthrosis joints.
syndsmosis and symphysis
Give examples of diarthrosis joints.
Synovial
What components does a synovial joint have?
Menisci, Burase, Fat pads, Ligaments, Capsule, synovial fluid, articular cartilage, joint cavity
What are the types of synovial joints?
Ball and socket, hinge, saddle, pivot, gliding and ellipsoidal.
What are the three types of movement a synovial joint can make?
Glide, angular movements and rotations
What ranges of motion can a synovial joint have regarding planes and axis?
Non-axial - gliding, Uni-axial - in one plane, Bi-axial - two planes, Multi-axial - in and around all planes and axis.
What movements can synovial joints make?
All of them. Flexion - extension, adduction - abduction, circumduction, hyperextension and rotation.
List the factors that limit synovial joint range of motion.
Surface, bony contact, ligaments, muscles, interposition of soft tissue, menisci and synovial fluid.
What is symphysis?
A fibrocartilaginous fusion between two bones, slight movement is possible (amphiarthrosis)
What is Syndesmosis?
A fiberous joint between bones linked by a ligament and strong membrane. Amphiarthrosis
What is Synchondrosis?
Immovable joint between bones bound by cartilage. Synarthrosis
What is Gomphosis?
Fiberous joint between tooth and socket. Synarthrosis.
