Intro Chap 1-7 Flashcards
Define fibrous joint
Held together by thin layer of periosteum
Define Cartilaginous joint and alternate name
Hyaline cartilage or fibrocartilage separate bone alternate name amphiarthrodial joint
Define synovial joint and alternate name
Bones are encapsulated and surrounded by synovial fluid
Types of fibrous joint and characteristic
Synarthrosis. Syndesmosis. Gomphosis. Provide great stability
Define synarthrosis and give example
Bones interlock, essentially no motion provides strength stability and shape. Skull sutures
Define syndesmosis and give example
Broad areas of ligaments and interosseous membranes hold the joint together allowing small amount twisting or stretching. Distal tibia/fibular joint
Define gomphosis and give example
Bolted together. Tooth socket
Define cartilaginous joint and characteristic
Allows small amount of bending,twisting or compression. Great stability
Alternate name for cartilaginous joint and example joint
Amphiarthrodial. Symphysis pubis, vertebrae and 1st sternocostal joint
Define synovial joint and Characteristic
Joint capsule made of strong fibrous tissue, filled with synovial fluid, articular surfaces smooth covered in hyaline cartilage. Less stable great mobility
Alternate name for synovial joint and examples
Diarthrodial. Knee hip elbow and shoulder
Synovial joint classifications
Biaxial, nonaxial, triaxial, uniaxial
Define biaxial and give example
Motion at 2 planes at condyloid or saddle joint. Wrist or cmc of thumb
Define nonaxial and give example
Gliding motion. Carpal bones-plane joints
Define traxial and give examples
A ball and socket joint allows motion I. All three planes. Shoulder hip
Define uniaxial and give example
Motion in one plane occurs at a hinge or pivot joint. Elbow
Define osteokinematics
End feel of joint motion can be measured by goniometer
Arthrokinematics define
Joint surface motion cannot be measure
Accessory motions 5
- Traction of distraction
- Approximation or compression
- Shearing
- bending
- rotary
Define traction or distraction
Joint surfaces pulling apart
Approximation or compression
Joint surfaces pushed together
Shearing
Both ends move parallel to and in opposite direction from each other
Bending
Compression on concave side and distraction on convex side
Rotary
Combination of compression and shearing
Arthrokinematic motion 3
Roll
Glide/slide
Spin
