Articulations/Joints Flashcards
Classification of Joints
Functional and Structural
Synarthrosis
No Movement (Fibrous)
Amphiarthrosis
Small Movement
Diarthrosis
Most Mobile (Synovial)
Examples of Synarthrosis
Sutures (interlocking skull), Gomphosis (Tooth socket), Synchodroses (Cartilage), Synotoses (Fused Bones)
Examples of Amphirathrosis
Syndesmosis (Ligaments), Symphsis (Fibrous Cartilage)
Examples of Diarthrosis
Long Bones, Articular Capsules lined with Synovial Membrane
Articular Cartilage
Smooth Surface, No Perichondrium, Rough if matrix breaks down
Synovial Membrane
Separates cartilage, Lubricates joints
Meniscus (Articular Disk)
Distributes weight and creates a even plane
Fat Pads
Protects the Cartilages
Ligaments
Connects Bone to Bone, Supports Bones
Intracapsular
In Joint Ligament
Extracapsular
Outside Ligament
Sprain
Torn Ligament
Tendon
Connects Muscle to Bone
Bursae
Pocket of Synovial Fluid
Dislocation/ Luxation
Surfacing forced out of position
Subluxation
Partial Dislocation
Structures of Joints
Fibrous, Synovial, Cartilage
Fibrous
Sutures, Syndesmosis, Gomphoses
Synovial
Plane, Hinge, Piviot, Ball and Socket ect…
