do the intrinsic muscles of the foot connect to the leg?
no, attach in the foot
how many layers of instrinsic muscles are there in the foot?
3
name the muscles responsible for short extension of the toes
2 dorsal muscles
name the muscles responsible for flexion of the foot?
sole muscles
name the muscles responsible for abduction/adduction of the toes
