| Question | Answer |
|---|---|
| T/F: The peroneus magnus muscle is considered a muscle of the lower leg's anterior compartment. | False |
| The soleus muscle only plantar flexes the ankle, and its main antagonist muscle is the | Tibialis Anterior |
| T/F: The soleus, plantaris, gastrocnemius, and popliteus muscles are all posterior leg muscles that plantar flex the ankle joint. | False |
| T/F: The subtalar joint is formed by the articulation between the talus and the calcaneus. | True |
| T/F: The tibialis anterior muscle dorsiflexes and abducts the foot. | False |
| T/F: There are seven tarsal bones in the foot. | True |
| Together with the tendon of insertion of the gastrocnemius, what muscle also is part of the Achilles tendon? | Soleus |
| When the muscles attached to the Achilles tendon contract, which of the following actions occurs at the ankle joint? | Plantar Flexion |
| When the sole (plantar) portion of the foot is moved downward, away from the lower leg and knee, the ankle joint movement is | Plantar Flexion |
| When the top (dorsal) portion of the foot is moved toward the lower leg and knee, the ankle joint movement is | Dorsiflexion |
| Which of the following flexes all four toes? | Flexor digitorum brevis |
| Which of the following muscles assists with the adduction of the third, fourth, and fifth toes (metatarsophalangeal joint)? | Plantar interossei |
| Which of the following muscles is not considered a primary inverter of the ankle joint? | peroneus tertius |
| Which of the following muscles is not considered an extrinsic muscle of a posterior compartment of the lower leg? | Extensor digitorum longus |
| Which of the following muscles is not considered an extrinsic muscle of the anterior compartment of the lower leg? | Peroneus brevis |
| Which of the following muscles would not be involved as a plantar flexor of the ankle joint? | Peroneus tertius |
| T/F: All four muscles of the quadriceps group are innervated by the femoral nerve. | True |
| T/F: Blood flow to the lower extremity progresses from the femoral artery, to the popliteal artery, and then to the anterior and posterior tibial arteries. | True |
| In the foot and ankle, two sites are frequently used to determine a pulse in the lower extremity: One site is the dorsal pedis artery and the other site is the | Posterior tibial artery |
| T/F: The arcuate and deep plantar arteries are branches of the dorsal pedis artery. | True |
