General Osteology Flashcards
Example of peg and socket joint.
Gomphosis - dentoalveolar syndesmosis.
Fibrous connection between tooth and its socket is known as periodontal ligament.
Complex joint.
Two or more articulating surfaces with articulate disc or meniscus in between.
Another name for synovial joints.
Diarthroses - freely movable joints.
Examples of fibrous joints.
Sutures.
Syndesmoses.
Gomphosis.
Types and examples of cartilaginous joints.
Primary - synchondrosis.
Secondary - symphysis.
Only type of cartilage which contains type 1 collagen.
Fibrocartilage.
Part of the bone not supplied by nutrient artery.
Epiphysis - Epiphyseal arteries.
Classification used for epiphyseal plate fracture in children.
Salter-Harris classification.
Types of epiphysis.
Pressure.
Traction.
Atavistic.
Aberrant.
Periosteum.
Layers.
Blood and nerve supply.
Thick fibrous layer which covers the outer surface of bones.
Continuous with the capsule of the joint.
2 layers - outer fibrous layer and inner cambium/osteogenic layer.
Blood supply by periosteal arteries.
Rich nerve supply - making it most sensitive part of the bone.
What connects periosteum to bone surface.
Sharpey’s fibres.
Types of bones.
Membranous.
Cartilaginous.
Membrano-cartilaginous.
Fabella.
Sesamoid bone found in the tendon of lateral head of the gastrocnemius muscle behind the lateral condyle of the femur.
Examples of pneumatic bones.
Sphenoid, ethmoid and maxilla.
Composition of bones connective tissue.
Inorganic calcium salts - make it hard and rigid - resistance to compressive forces and impact forces.
Organic connective tissue - make it tough and resilient - resistance to tensile forces.
