Final answer:
The dorsiflexors terminate their action by the end of the terminal stance phase of the gait cycle.
Step-by-step explanation:
In regards to a normal gait pattern, the dorsiflexors terminate their action by the end of the terminal stance phase. The sequence of gait begins with the heel strike of one foot and ends with the push off of the toes of that same foot to initiate the heel strike of the other foot. Therefore, the correct answer to the question would be: C. The end of terminal stance
The terminal stance phase is where the heel of the foot starts to lift off the ground, and the body prepares for the swing phase.
At this point, the dorsiflexors are ending their action to allow the foot to begin plantar flexion in preparation for the toe-off and the subsequent swing phase.
