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

Extensor Digitorum Longus

Which of the following muscles can perform extension of the greater toe when concentrically contracting?

Extensor Hallucis Longus

Which of the following muscles is innervated by the deep peroneal nerve (L4, L5, S1)

Extensor hallucis longus

T/F: Both the tibialis posterior and the flexor digitorum longs are innervated by the tibial nerve (S1, S2)

False

T/F: Each toe has three interphalangeal joints, except the great toe, which only has two.

False

T/F: 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

T/F: Supination is a combination of ankle dorsiflexion, subtalar eversion, and forefoot abduction

False

T/F: The most common type of ankle sprain results from excessive eversion that causes damage to the anterior talofibular ligament

False

Flexor Digitorum Longus

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

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

Peroneus (fibularis) longus

Which of the following muscles only performs plantar flexion?

Soleus

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

Tibialis Posterior, Flexor digitorum longus, Flexor hallucis longus

T/F: During midstance, the foot should be in pronation and the leg should be in internal rotation

True

T/F: Heel-strike normally occurs by landing on the heel with the foot in supination and the leg in external rotation. _______

True

T/F: Motions of the metatarsophalangeal joints of the toes include flexion, extension, abduction, and adduction

True

T/F: 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

T/F: The flexor hallucis longus muscle is innervated by the tibial nerve (L5, S1, S2)

True

T/F: The gastrocnemius muscle is innervated by the tibial nerve (S1, S2).

True

T/F: The tibialis anterior performs dorsiflexion of the ankle in the sagittal plane

True

T/F: Toe flexion is movement of the toes toward the plantar surface of the foot

True
