Question
Chapter 9, Problem 9CYU
Summary Introduction
To review:
The reason behind having a number of large muscles involved in the plantar flexion of the foot as compared to its dorsiflexion.
Introduction:
There are many intricate and muscle-controlled movements occurs in the feet as well as toes, which are involved in activities as seemingly simple as walking. The movements get more intricate as the activities get more complex. The feet and toes perform such movements.
