All of these answers are correct

Which of the following muscles can perform extension of the lesser toes when concentrically contracting?

Each toe has three interphalangeal joints, except the great toe, which only has two.

FALSE

Immediately prior to and during normal toe-off, the foot should be in pronation and the leg should be in external rotation.

FALSE

Inversion is turning the ankle and foot outward away from the midline of the body where the weight is on the medial edge of foot.

FALSE

Flexor digitorum longus

Which of the following muscles can perform flexion of the great toe when concentrically contracting?

Flexor hallucis longus

Flexor hallucis longus

Proximal interphalangeal joint motion occurs about the ________ axis.

Frontal

Which of the following muscles has its insertion on the posterior surface of the calcaneus?

Gastrocnemius

Which of the following is NOT considered to be a muscular compartment of the lower leg?

Medial compartment

Which of the following muscles has its origins on the head and upper 2/3rd of lateral surface of the fibula?

Which of the following muscles does NOT perform plantar flexion?

Peroneus (Fibularis) tertius

Which of the following muscles is included in the anterior compartment?

Peroneus (Fibularis) tertius

Which of the following muscles only performs plantar flexion?

Soleus

Heel-strike normally occurs by landing on the heel with the foot in supination and the leg in external rotation.

TRUE

Motions of the metatarsophalangeal joints of the toes include flexion, extension, abduction, and adduction.

TRUE

Pronation is a combination of ankle dorsiflexion, subtalar eversion, and forefoot abduction.

TRUE

The distal malleoli of the tibia and fibula serve as pulleys for the posterior tendons to increase the mechanical advantage of the respective muscles in performing inversion and eversion actions.

TRUE

The flexor hallucis longus muscle is innervated by the tibial nerve (L5, S1, S2).

TRUE

The gastrocnemius muscle is innervated by the tibial nerve (S1, S2).

TRUE

The most common type of ankle sprain results from excessive inversion that causes damage to the anterior talofibular ligament.

TRUE

The tibialis anterior performs dorsiflexion of the ankle in the sagittal plane.

TRUE

Toe flexion is movement of the toes toward the plantar surface of the foot.

TRUE

Which of the following muscles can perform inversion of the foot when concentrically contracting?

Tibialis anterior

Which of the following muscles has its insertion on the inner surface of the medial cuneiform and base of the 1st metatarsal bones?

Tibialis anterior

The "Tom, Dick, and Harry" phrase refers to the _________________, respectively.

Tibialis posterior, flexor digitorum longus, flexor hallucis longus
