Which is an eccentric function of the flexor hallucis brevis?
A)restrains/slows extension of the big toe (toe number one)at the metatarsophalangeal joint
B)restrains/slows inversion of the foot at the subtalar joint
C)restrains/slows flexion of the big toe (toe number one)at the metatarsophalangeal joint

Question

Quizplus · Accepted Answer

The flexor hallucis brevis is a muscle of the foot that primarily acts to flex the big toe at the metatarsophalangeal joint. In an eccentric function, where the muscle lengthens under tension, it would help to control or slow down the extension of the big toe, making option A correct. Options B, C, and D are incorrect as they describe actions not associated with the eccentric function of the flexor hallucis brevis or involve different joints or limbs.
