what are two ways of classifying joints |
structural classification functional classification |
|
|
what is the functional classificaion of a synovial joint |
Diarthrosis |
|
|
what are the key features of the synovial joint and what are their functions |
-capsule - strength and support -synovial membrance - produces synovial fluids/ lines the capsule and non articular structures - Synovial fluid – within the capsule/joint space – it is an essential lubricant and nutrient supply to the cartilage -Hyaline cartilage – lines articular surfaces |
|
|
what are examples of synovial joints |
ball and socket - hip/shoulder
hinge join - elbow plane or gliding joint - posterior vertebral joints sellar(saddle joint) - first carpometacarpal joint |
|
|
what are fibrous joints |
joints where bone margins are united by a layer of fibrous tissue. because they are immovable they can also be called synarthroses. |
|
|
what are examples of fibrous joints |
the inferior tibofibular joint in the ankle |
|
|
what are cartilaginous joints |
joints that move slightly - amphiarthrosis - the bone ends are united by cartilage |
|
|
what are examples of cartliaginous joints |
joints between the pubic bones and between vertabral bodies |
|
|
why is a cartilaginous joint also known as a symphysis joint |
because the joint surfaces are covered in hyaline cartilage and are seperated by a disk of fibrocartilage which functions as a shock absorber |
|
|
what type of joint does and elbow have? and what movement does it do? |
elbow = hinge joint range of movement: extension + flexion +pivot |
|
|
what type of joint does and knee have? and what movement does it do?
|
knee = modified hinge join ROM: extension+flexion+piviot with extended knee |
|
|
what type of joint does and shoulder have? and what movement does it do?
|
shoulder= ball and socket joint ROM: extension+flexion+abduction+aduction |
|
|
where is the acromioclavicularjoint found and what type of joint is it and what is it ROM |
it is in the shoulder and is a gliding/plane joint. ROM includes: gliding |
|
|
where is the proximal radioulna joint found and what type of joint is it and what is it ROM
|
it joins the ulna and radius to the humerus - it is a pivot joint and ROM includes rotation |
|
|
what is an example of a saddle joint |
first carpometacarpal joint - in the base of the thumb ROM - flexion extension aduction abduction rotation |
