Which joints are primarily responsible for the flexion and extension of the toes?
Understand the Problem
The question is asking about the specific joints in the foot that facilitate the movement of flexion and extension of the toes. It presents multiple choice answers to identify which joint type is primarily involved in this action.
Answer
Interphalangeal joints are responsible for toe flexion and extension.
The interphalangeal joints are primarily responsible for the flexion and extension of the toes.
Answer for screen readers
The interphalangeal joints are primarily responsible for the flexion and extension of the toes.
More Information
Each of the toes, except the great toe, has both proximal and distal interphalangeal joints that facilitate flexion and extension, while the great toe has only one interphalangeal joint.
Tips
Do not confuse the interphalangeal joints with the metatarsophalangeal joints which also allow for toe movement but have additional functions.
