Flashcards in Joints, Muscle And Blood Supply Deck (30)
What does arthroses mean? What are types of arthroses?
Synarthroses and diarthroses
What type of joints connect bones to bones via tissue? Its function
Stabilziation rather than movement
What are two types of synarthroses?
Where are suture joints founded? Where are Gomphosis founded?
Flat bones of skull (dense short fiber)
Short dense fiber btw tooth and tooth socket
What joints held together by ligament? How is it fibrous tissue compare to suture's?
What type of joint suture, gomphosis & syndesmosis are?
What joint is primary in cartilaginous joint?
What joint made of hyaline cartilage? Where is it?
Sternum & ribs
What joint made of fibrocartilage? Where is it?
What joint that bone indirectly connect via the joint capsule?
What are components of synovial joint?
Joint capsule made of fibrous tissue
Joint cavity enclosed by capsule
Synovial membrane lining capsule
Synovial fluid covering joint surface
Hyaline cartilage cover joint surfaces
How does hyaline cartilage get its nutrients? Why?
From joints movement. Because it doesnt have blood supply
What ligament and tendons do to diarthrose? Labrum? Fat pads?
Where else fibrocartilaginous disks founded?
In diarthroses - joint capsule
How diarthroses categorized?
Based on degree of freedom
Uniaxial? What are those joints?
Flexion and Extension
Where do you find hinge joint?
Interphalanges and elbow joint
How does pivot joint work?
Rotation about an axis
What is biaxial? Where do you find them?
Flexion and Extension + adduction and abduction
Condyloid: metacarpal joints
What is triaxial? Where you can find them?
Flex/ext + abd/add + circumduction
Ball and socket: hip and shoulder
What joint motions are there?
When closed-packed joints happen?
When bones are the closest, joint space is smaller/ ligament and tendons are tight
Example o closed packed joint?
What are main factors for stabilization joints?
Shape of articulating surface
Presence of ligaments
What is dynamic stability?
When muscles stabilizes joint so it can move
What blood come to your arm?
Split into common coratid and subclavian
Is there subclavian trunk on the left?
Vertebral blood supply what?
B5 to part of spinal cord
