chapter 16
Which two tarsals does the talus articulate with?
Calcaneus and navicular
Which of the following pairs of structures directly bears the body weight when standing?
Distal ends of the metatarsals; calcaneus
What is the function of the sesamoid bones in the tendons of the flexor hallucis brevis?
Hold the body's weight off the flexor hallucis longus tendon
Branches of which artery supply the leg and foot?
Medial plantar artery
Which of the following nerves innervates all the muscles below the knee?
Sciatic
Which compartment of the leg contains the major propulsive muscles, in human locomotion?
Superficial posterior
Which of the following is not a difference between a human foot and a human hand?
The extrinsic muscles of the foot have even greater differentiation than those of the hand
Which compartment of the leg contains muscles that dorsiflex the foot?
anterior
The superficial depressor muscles of the leg attach to the:
calcaneus
Intrinsic toe extensors lie superficial to the extrinsic muscle tendons on the dorsum of the foot.
false
Studies confirm that the popliteus muscle plays an important role during human walking.
false
Tendons of the fibularis muscles wrap around the medial malleolus on their course into the foot.
false
The fibula is weight bearing
false
The only toe flexor is an intrinsic, rather than extrinsic, foot muscle.
false
The tendon of the flexor digitorum longus muscle runs in a straight line to the toes.
false
The three muscles of the deep layer of the posterior compartment of the leg retain consistent organization as they pass into the foot.
false
The tibia and fibula can move, relative to each other, as much as the radius and ulna can in the forearm.
false
The tibial nerve courses deep to the deep flexor muscles in the posterior leg.
false
The tibialis anterior muscle is supplied by an anterior division nerve.
false
Medial and lateral plantar nerves are branches of:
tibial nerve
None of the muscles which dorsiflex the foot cross the knee joint.
true
The bones of the leg only contact one tarsal: the talus.
true
The joint between the tibia and talus only allows flexion and extension of the foot.
true
The mammalian heel is formed by the calcaneus.
true
The plantar aponeurosis supports the longitudinal arch of the foot.
true
The sciatic nerve consists of both an anterior and a posterior division nerve, bound together.
true
The sciatic nerve innervates all the muscles below the knee.
true
The tendons of the muscles of the deep layer of the posterior compartment of the leg wrap around the medial malleolus as they pass into the foot.
true
The thenar/hypothenar muscle equivalents of the lower limb contribute to maintaining the longitudinal arch.
true
