Joints lecture 5 & 6 Flashcards
Whats my mnemonic for remembering
Harry potter shouldnt ever consider playing basketball
What are the 7 synovial joint types
Hinge, pivot, saddle, ellipsoid, condyler, plane, ball and socket
joint type of sutures on skull
fibrous joint
name of the joint between the vertebrae or between os coxae
cartilaginous
Saddle joint: axis, movements, example
thumb first carpometacarpal joint, biaxial, extend & flex, abduct and add also opposition
Hinge joint: axial movement, movements and example
elbow, uniaxial flexion and extension
pivot joint, axis, movement and example
uniaxial, rotation, the C1 and C2 vertebrae
delete
delete
ellipsoid, axis, movement and example
biaxial, flexion, extension, abduction and adduction, circumduction, not rotation, wrist joint
condylar joint: axis, movement and example
biaxial, extension and flexion, rotation when flexed, knee joint
Plane joint; axis, movement, example
intercarpal joints are multiaxial as they slide past one another in all directions
Ball and socket: movement, example and axis
multiaxial, shoulder, flexion, extension, adduction, abduction, circumduction, rotation
Whats joint loading
force on the tissues of the joints, like menisci, which compresses them forcing them to absorb nutrients.
Where does the ACL connect:
Anterior of tibia to posterior of femur
Where does PCL connect
posterior of tibia and anterior of femur
difference between joint class and type
class is the overarching group, so fibrous, cartilagenous or synovial, type is what HPSECPB it is within class
where does the medial collateral ligament connect
tibia to femur
where does the lateral collateral ligament connect
femur to fibula
what is the process of f transforming cartilage to
bone called
endochondral ossification
whats the function of fibrocartilage
resist compression and tension
function of hyaline cartilage
resist compression
two examples of fibrous joint
sutures and distal tibiofibular joint. As this fibrous is why we can supinate these bones, they must provide more support
structure of ligaments
have high elastin which allows them to stretch and recoil,. They can keep the bone where its meant to be easily for this fact. DFCT, collagen aussi
structure of tendons
As fibres are alinged in these structures they resist tension well. little elastin more collagen
Ligaments and tendons are made of what generally
dense fibrous connective tissue. Made of collagen and elastin, hardly any ground substance, instead they are mostly cartilage.
what kinds of cells work in DFCT
Fibroblasts make the DFCT and fibroblasts destroy it.
risk factors of osteoporosis
age, female( post menopausal) lifestyle factors like diet and nutrients and that, peak bone mass
collateral ligaments can also be called
capsular ligaments
cruciate ligaments can also be called
intracapsular ligaments
what provides nutrients to avascular structures
synovial fluid
