Question
Chapter 11, Problem 13CYU
Summary Introduction
To review:
The name of the two muscles working as synergists as well as prime movers in plantar flexion.
Introduction:
Anatomical compartments are formed by the means of dense fibrous connective tissue which is responsible for the division of muscle mass into various compartments. The leg region contains three compartments which include posterior, anterior, and lateral compartments.

What are two factors which allow the gastrocnemius and soleus muscles to generate greater plantar flexion torque than all the other muscles capable of plantarflexion?
Explain the role of agonist, antagonist, synergist, and fixator muscles. Give two examples of each.

Provide an example to illustrate the use of each criterion.arrow_forwardIdentify the muscles that are involved in the following movements: Knee Extension Knee Flexsion Knee Fytenarrow_forwardDistinguish between a synergist, antagonist, and fixator. Explain how each of these may affect the action of a prime mover.arrow_forward
- Describe each of the below muscle actions and list at least one muscle that creates the action.Lower Extremity Muscle Actions: · Knee flexion · Knee extension · Knee medial rotation · Knee lateral rotation · Dorsiflexion · Plantarflexion · Foot inversion · Foot eversion · Foot digits flexion · Foot digits extension· Hip flexion · Hip extension · Hip medial rotation · Hip lateral rotation · Hip abduction · Hip adduction *PLEASE ANSWER ALL IF POSSIBLE.arrow_forwardDescribe the roles of plantar flexion and dorsiflexion inwalking. What muscles produce these actions?arrow_forwardWhy can you lift a larger load when your elbow is slightly flexed and your biceps muscle is at an intermediate length than you can when your elbow is fully extended?arrow_forward
- Define a lever.arrow_forwardWhat muscles are being used in this picture? (hint: there are quite a few – write down each joint movement and the muscles that are responsible)arrow_forwardAn isometric exercise is one in which the joint angle does not change during the application of muscle force. For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.arrow_forward
