what is the TFL and where is it located?
tensor fasciae latae
what is the iliotibial tract?
thickened portion of the fascia latae that extends from the iliac crest to the knee
obturator muscles
obturator externus (adduction)

what are intrinsic foot muscles?
- group of muscle that originate and insert within the foot
- 2 groups: plantar and dorsal
a pair of small triangle-shaped muscles found among the posterior hip
superior and inferior gemellus
what is the role of the intrinsic foot muscles?
they help to flex, extend, abduct, and adduct the toes
