Exam 10: The Ankle and Foot Joints

Which of the following muscles may be palpated on the upper lateral side of the tibia; just distal to fibular head and down to immediately posterior to lateral malleolus?

Which of the following muscles has its insertion on the base of the distal phalanx of each of the four lesser toes and causes movement posteriorly about the frontal plane when contracting concentrically?

The ankle and foot joints are composed of 26 bones in each foot if not considering the sesamoid and accessory bones.

Which of the following muscles are agonist in all of their concentric actions at the talocrural joint?

Dorsiflexion, the dorsal aspect of the foot moving toward the anterior tibia, occurs through eccentric contractions of the tibialis anterior, extensor digitorum longus, extensor hallucis longus and fibularis tertius.

The distal malleoli of the tibia and fibula serve as pulleys for the posterior tendons of the posterior tibialis and peroneus brevis to increase the mechanical advantage of these muscles in performing inversion and eversion actions, respectively.

Pronation is a combination of ankle dorsiflexion, subtalar eversion, and forefoot abduction, whether actively or passively.

The soleus muscle can perform muscular actions only in the sagittal plane about a frontal axis.

Motions of the toe metacarpophalangeal joints include flexion, extension, abduction, and adduction.

Which of the following has the most potential for requiring emergency care?

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

The gastrocnemius is more effective as a plantar flexor when the knee is:

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

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

Which of the following muscles are agonist to each other when performing eccentric actions in the frontal plane?

Both the tibialis anterior muscle and the extensor digitorum longus muscle are innervated by the tibial nerve (L5, S1).

The only foot extrinsic muscle involved in extending all of the metacarpophalangeal and interphalangeal joints of the four lesser toes is the extensor digitorum longus.

Which of the following statements is not true regarding "shin splints?"

Each toe has three phalanxes except for the great toe which has only two.

Which of the following insert on the base of the 5 ^th metatarsal?
