Question 1

Superior Surface of the Patella

Answer 1

Four quadriceps femoris muscles of the thigh converge on

Question 2

Patella Ligament

Answer 2

Arising from the the inferior border and extending to the prominent tibial tuberosity.

Question 3

Iliotibial tract

Answer 3

Location: posterior lateral aspect of the thigh
Function: thickening of fascia lata
Important stabilizing action at the knee joint.

Question 4

Biceps femoris

Answer 4

Posterior to the iliotibial tract

Question 5

Dorsiflexion

Answer 5

Motion of the foot

Location: bending the top dorsal surface of the foot to lift the toes

Question 6

Plantarflexion

Answer 6

Motion of the foot

moving the bottom or sole of the foot to raise the heel

Question 7

Inversion

Answer 7

Motion of the foot

rotation of the sole inward

Question 8

Eversion

Answer 8

Motion of the foot

rotation of the sole laterally

Question 9

Tibialis Anterior

Answer 9

Location: extends from the upper two thirds of the tibia to the medial cuneifrom and base of the first metatarsal bones
Function: acts to both dorsiflex and invert the foot

Question 10

Shin splints

Answer 10

Occurs when fibers of the tibialis anterior muscles separate from the tibia

Question 11

Peroneus Tertius

Answer 11

Location: originate from the fibula, tendon that crosses the top of the foot to attach to the 5th metatarsal bone
Function: assists the tibialis anterior muscle in dorsiflexion of the foot.

Question 12

Peroneus Longus

Answer 12

Location: Originates at the fibula. has long tendon that surves around the lateral malleolus of the tibula, crosses the sole of the foot to reach the medial cuneiform and the first metatarsal bones

Question 13

Peroneus Brevis

Answer 13

Location: originates at the fibula. Includes a tendon that curves around the lateral malleolus of the fibula, attaches to the nearby 5th metatarsal bone.

Question 14

Peroneus muscles (function)

Answer 14

alll act to evert the foot

Question 15

four muscles related to plantar flexion

Answer 15

Gastrocneumius, soleus, peroneus longus, and peroneus brevis.

Question 16

Gastrocnemius muscles

Answer 16

Location: arises from the medial and lateral condyles of the femur to embrace either side of the popliteal fossa located behind the knee joint,
Function: has two heads, because it crosses the knee joint, Action:flexion of the leg

Question 17

Soleus

Answer 17

Location: deep to the gastrocnemius and is quite flat, Originates from the tibia and fibula to join the gastrocnemius

Question 18

Achilles (Calcaneal) tendon

Answer 18

Shared common tendon btwn the soleus and gastrocnemius

Location: inserts on the calcaneus

Question 19

Gastrocnemius and soleus (Function)

Answer 19

calif muscles act in powerful plantarflexion of the foot, lifting the heel when we push off in walking and running

Extensor Digitorum Longus

Answer 20

Location: 4 tendons that reach the lateral four toes (Does not include the great toe)

Question 21

Extensor Digitorum Brevis

Answer 21

Location: 4 tendons that reach the medial four toes.

Extensor Hallucis Longus and Brevis

Answer 22

Location: tendon to the great big toe

Question 23

Longus muscles

Answer 23

Location: extrinsic (Outside the foot)

Question 24

Brevis

Answer 24

Location: intrinsic (Originating within the foot)

Question 25

Extensor Retinaculum

Answer 25

Holds down the tendons of the extrinsic muscles
Made of resilient fibers
Location: crossing the anterior and lateral surfaces of the ankle
