A. superb dexterity C. mobility B. manipulation D. stability The lower limb is designed for locomotion and is most adept for which of the following?

C. mobility D. stability The lower limb is designed for locomotion and is most adept for which of the following?

Back to Board The lower limb sacrifices mobility to gain the stability necessary to bear the body’s weight.

A. flexion C. rotation B. extension D. circumduction In order for a person to lift their leg to get into a car, what action of the hip must be achieved?

A. flexion C. rotation In order for a person to lift their leg to get into a car, what action of the hip must be achieved?

Back to Board Remember to flex your hip when you get into a car.

A. right C. left & right B. left D. not listed As a person lifts his/her right foot to walk, the hip abductors on which side of the body stabilize the hip?

A. rightB. left As a person lifts his/her right foot to walk, the hip abductors on which side of the body stabilize the hip?

Back to Board When the right foot is raised, left hip abductors contract to prevent the pelvis from tipping down to the unsupported side.

A. away from midline C. no change from midline B. toward midline D. along midline If a person laterally rotates their left hip, in what direction (relative to the body’s midline) will the left big toe move?

A. away from midlineB. toward midline If a person laterally rotates their left hip, in what direction (relative to the body’s midline) will the left big toe move?

Back to Board Lateral rotation of the hip moves the big toe away from midline.

A. abduction C. circumduction B. adduction D. flexion All of the muscles that move the thigh are responsible for what action?

C. circumduction B. adduction All of the muscles that move the thigh are responsible for what action?

Back to Board All muscles that move the thigh are used during circumduction.

A. hip C. ankle B. knee D. waist Where does leg flexion and extension occur?

A. hipB. knee Where does leg flexion and extension occur?

Back to Board The leg extends from knee to ankle, so flexion and extension of the leg occurs at the knee.

A. anterior cruciate C. medial collateral B. posterior cruciate D. lateral collateral For a child that has “bowed-legs”, which ligaments on both knees are under the most physical stress?

A. anterior cruciate D. lateral collateral For a child that has “bowed-legs”, which ligaments on both knees are under the most physical stress?

Back to Board In genu varus or bow-legs, the lateral collateral ligaments are most stretched.

A. dorsiflexion C. pronation B. plantarflexion D. supination When one presses the gas pedal in a car, what movement of the foot is taking place?

A. dorsiflexionB. plantarflexion When one presses the gas pedal in a car, what movement of the foot is taking place?

Back to Board Plantarflexion points the toe, while dorsiflexion brings the top of the foot, or dorsum, up toward the anterior surface of the leg.

A. inversion C. circumduction B. eversion D. rotation The sole of the foot moves toward the midline during what action of the ankle and foot?

A. inversionB. eversion The sole of the foot moves toward the midline during what action of the ankle and foot?

Back to Board Inversion brings the sole of the foot in to face medially; eversion moves the sole to face out laterally.

A. metatarsophalangeal C. distal interphalangeal B. proximal interphalangeal D. tarsometatarsal Which of the following joints is NOT involved in the flexion and extension of the toes?

A. metatarsophalangeal D. tarsometatarsal Which of the following joints is NOT involved in the flexion and extension of the toes?

Back to Board The tarsometatarsal joints provide very limited movement, and is not involved in toe flexion.

A. flexion C. inversion B. extension D. eversion When a runner wants to get a good jumpstart in a race, he or she depends on what action of the hallux to help him/her push off?

A. flexion C. inversion When a runner wants to get a good jumpstart in a race, he or she depends on what action of the hallux to help him/her push off?

Back to Board In pushing off, the big toe or hallux is flexed.

A. 1 st toe (hallux) C. 3 rd toe B. 2 nd toe D. 4 th toe Which toe serves as the point of reference when discussing the abduction and adduction of the toes?

C. 3 rd toe B. 2 nd toe Which toe serves as the point of reference when discussing the abduction and adduction of the toes?

Back to Board In the foot, ab- and adduction occur in reference to the 2nd toe.

Sorry, that is incorrect!
