Manus muscles Flashcards
flexor retinaculum
accessory carpal
attaches on palmar aspect of medial carpal bones
creates space called carpal canal
interflexorii
Tendinous strips arising from DDF, passes through the canal
lumbricales
found between tendons of DDF, insert on capsule of metacarpophalangeal joint
palmar annular ligament
Held onto deep scutum.
Hold the SDF and DDF tendons in place at the metacarpophalangeal joint
interosseous - flex the MCPj, prevent over extension
proximal end of MC2-5 via sesamoid bones paired to…
- paired tubercles on phalanx 1 of digits 2-5
- via tendinous slips pass around digits to exgensor tendons
proximal and distal digitial annular ligaments
binding tendons to p1 and p2
flexor retinacula
carpal FA - accessory to medial carpals, forms carpal canal
palmar annular ligament - proximal sesamoid bones
proximal digital annular ligament holds tendons against p1
distal digital annular ligament - holds tendons against palmar p2
carpal check ligament
ddft
radial check ligament
sdft
extensor slips
Pass dorsally around P1 to blend with the common digit extensor tendon
straight ligaments
palmar to proximal p2
oblique ligaments
palmar distal p1
cruciate ligaments
palmar proximal p1
short ligaments
palmar proximal p1
collateral ligaments
pastern and coffin joint. also receives extra support from axial and abaxial palmar ligaments
