FLEXOR DIGITORUM LONGUS M

Question 1

when is the FDL active?

Answer 1

end of contact-mid propulsion

Question 2

when does the FDL begin function?m(in terms of muscle working)

Answer 2

before the FHL because the lesser digits contact the ground first

Question 3

what are the pulleys that affect the FDL?

Answer 3

medial malleolus and sustenaculum
-allows FDL to function as supinator
transverse metatarsal ligament
-stabilizes the digits plantarly

Question 4

what is the primary function of the FDL?

Answer 4

maintains stability of the lesser digits against ground during propulsion (major role)

• applies posterior compression on phalanges of lesser digits against met heads during midstance and propulsion
• -this relies on quadratus plantae for this

Question 5

this is a good supinator(plantarflexion and adductor) of forefoot relative to rearfoot?

Answer 5
