Joints Flashcards
What are the 3 types of joints categorised by ROM
Immoveable (skull) Slightly moveable (tib and fib - joined by cartilege, vertebrae) Freely moveable joints
A freely moveable joint is always a s_____________ joint
synovial
what is the relationship between joint movement and injury likelihood
the more moveable a joint the less stable and more prone to injury
joints that need ability have less movement
What do ligaments connect
bone to bone
also support some internal organs
Is a flexible person more or less prone to injury
A flexible person is more prone to injury
What is the preferable way for scar tissue to lay down and how is that achieved
scar tissue is best laid down in smooth flat pattern - proper movement aids in the laying down of scar tissue in a beneficial way and can help untangle disorganised bundles of scar tissue
what are proprioceptors
The cells within ligaments that tells the body where the joint is and whether it is moving
The muscles respond to the communications from the proprioceptors to move and relax to keep us balanced
WHat is an example of an articular disc
knee - meniscus
what lubricates the articular discs
synovial fluid
How do you ensure a joint is properly lubricated with synovial fluid
full range of movement of the joint
what are bursae
fluid pockets allow muscles and tendons to glide over each other or around a joint
What is the job of synovial membrane
to secrete and absorb synovial fluid
What effects the viscosity of synovial fluid
temperature, joint movement, pH
what are the three jobs of synovial fluid
lubrication
nutrient distribution
shock adbsorption
