ACTIONS

Question 1

ABDUCTOR HALLUCIS M

Answer 1

abducts the hallux (moves it away from the midline of the foot); aids in plantar flexion of the hallux

Question 2

ABDUCTOR DIGITI MINIMI M

Answer 2

abducts the 5th toe; aids in plantar flexion of the 5th toe

Question 3

FLEXOR DIGITORUM BREVIS M

Answer 3

plantar flex the lesser digits, begins at the proximal interphalangeal joints then the metatarsophalangeal joints

Question 4

QUADRATUS PLANTAE M

Answer 4

modifies the direction of pull of the flexor digitorum longus muscle (modifies the action of the flexor digitorum longus muscle); the flexor
digitorum longus muscle will pull in a more posterior direction instead of
a medial posterior direction

Question 5

LUMBRICALS

Answer 5

plantar flex / flex the metatarsophalangeal joints and dorsiflex / extend the proximal and distal interphalangeal joints (PIPJs and DIPJs) of the lesser
toes, simultaneously (the bye-bye muscles); ex. 1st lumbrical muscle acts
upon the 2nd toe, etc.

Question 6

FLEXOR HALLUCIS BREVIS M

Answer 6

plantar flexes / flexes the hallux at the metatarsophalangeal joint

Question 7

FLEXOR DIGITI MINIMI BREVIS M

Answer 7

plantar flexion (flexion) of the 5th digit at the metatarsophalangeal joint; some abduction of the 5th digit often occurs

Question 8

ADDUCTOR HALLUCIS M

Answer 8

adducts the hallux (toward the midline of the foot); aids in plantar flexion of the hallux

Question 9

PLANTAR INTEROSSEI M

Answer 9

adduct digits 3, 4 and 5, respectively (toward the midline of the foot) ex. the
1st plantar interosseous muscle adducts the 3rd toe, the 2nd plantar interosseous muscle adducts the 4th toe and the 3rd plantar interosseous
muscle adducts the 5th toe

Question 10

DORSAL INTEROSSEI M

Answer 10

abduct toes 2, 3 and 4 (from the midline of the foot), 1st and 2nd abduct the
2nd toe, 3rd abducts the 3rd toe and 4th abducts the 4th toe
