General Anatomy- Some Joints Flashcards
TMJ- classification, innervation, movement
Compound hinge + gliding jt (covered by fibrocartilage- more resistant to damage)
Intra articular disc separates an upper and lower compartment
inn. Auriculotemporal, deep temporal, mesenteric branches of CNv3
Where does protraction + retraction and elevation + depression occur in the TMJ
Upper- protraction and retraction
Lower- elevation and depression
What inn the glenohumeral jt
Axillary and suprascap n
Sternoclavivular jt- type, classification, inn
type- synovial with an intra articular disc
Classification- saddle type but behaves like ball and socket
inn- medial branch of supraclavicular nerves C3
Elbow jt type, classification and inn
type- synovial
classification- hinge
innervation- radial and musculocutaneous nerves
Prox + distal radioulnar jts - type, classification, inn
synovial pivot jt
inn- median, ulnar and radial
Wrist jt- type, classification, inn
synovial
condyloid
inn. radial, medial, ulnar
1st carpometacarpal jt- type, classification, inn, bones involved
synovial saddle type joint
Trapezium + 1st metacarpal bone
Inn- radial and median nerves
metacarpophalangeal jt- type, classification, inn
synovial condyloid jt
Inn- median, ulnar and radial
What mm adducts/abducts the mcps
add- palmar interossei (PAD)
Abduction- dorsal interossei (DAB)
Interphalangeal jt- type, classification, inn
synovial hinge jt
inn- median, ulnar and radial nerves
Hip joint type, classification and inn
Synovial ball and socket
inn- femoral, obturator and nerve to quadrates femoris
What is the intra articular lig of the hip jt (+ what does it contain)
round lig of tea of the femur- from transverse acetabular lig and the rim of acetabular notch to fovea centralis
What are the extra articular ligs of the hip jt (+what do each limit/run from)
- Iliofemoral- asis to femoral neck (prevents hyperext)
- Pubofemoral- sup pubic ramus to lower capsule (prevents hyperabduction)
- Ischiofemoral- ischium to post part of capsule (prevents hyperextension)
Knee joint- type, classification, inn
Synovial modified hinge
inn- femoral, tibial, common peroneal
acl and mcl- origin + insertion
ACL- ant part of intercondylar ridge and attached to post medial aspect of lat condyle of femur
PCL- post part of intercondylar ridge to lat aspect of medial condyle of femur
what is the medial meniscus attached to
attached to MCL
semilunar shape
Ankle joint type, classification and innervation
synovial hinge joint
inn- tibial and deep perineal nerves
