| Question | Answer |
|---|---|

| What is the name of the ankle joint? | Talocrural |
| What is the agonist for plantar flexion? | Soleus |
| What muscle has the longest tendon in the body? | Plantaris |
| What muscle is known as the second heart pump due to its function of helping return blood to the body from the lower extremities? | Soleus |
| The Key that Unlocks the Knee | Popliteus |
| When a muscle isn't taking an action, it is relaxed and allowed to lengthen. We call this… | Stretching |
| Posterior calf muscle that inverts the foot | Tibialis posterior |
| O - proximal, posterior tibia and fibula and interosseous membrane I - medial arch of the foot | Tibialis posterior |
| O - middle posterior tibia I - distal phalanges of 2nd thru 5th toes | Flexor digitorum longus |
| O - middle posterior fibula I - distal phlange of the first toe | Flexor hallucis longus |
| Flexes the four lateral toes | Flexor digitorum longus |
| Flexes the big toe | Flexor hallucis longus |
| If a muscle or its tendon goes behind either malleolus, it will perform this action. | Plantar flexion |
| O - Lateral epicondyle of the femur I - Proximal, posterior aspect of the tibia | Popliteus |
| Turning the foot so that the sole is facing medially is called… | Inversion |
| Turning the foot so that the sole is facing laterally is called… | Eversion |
| Flexing the ankle so that the toes point down is called… | Plantar flexion |
| Flexing the ankle so that the toes point towards the shin is called… | Dorsiflexion |
| The joint of the ankle were the fibula meets the tarsals is called… | Talofibular |
| The ankle joint most often hurt during an inversion ankle sprain is the … | Talofibular |
| What is the proximal end of the fibula called? | Head |
| Tom, Dick, an' Harry refers to the order of structures located around this area. | Medial Malleolus |
| Largest sesamoid bone in the body | Patella |
| Name of the knee joint | Tibiofemoral |
| What kind of joint is the knee joint? | Modified hinge |
| All toe flexors are found on what part of the leg? | Posterior |
| This refers to the four lateral toes | Digitorum |
| This refers to the big toe | Hallucis |

| What is the distal end of the fibula called? | Lateral malleolus |
| What is the distal end of the tibia called? | Medial malleolus |
| What is the name of the ankle joint? | Talocrural |
| What is the proximal end of the fibula called? | Head |
| When a muscle isn't performing an action, it is relaxed and allowed to lengthen. We call this… | Stretching |
| If a muscle or its tendon goes in front of either malleolus, it will perform this action. | Dorsiflexion |
| Turning the foot so that the sole is facing medially is called… | Inversion |
| Turning the foot so that the sole is facing laterally is called… | Eversion |
| O - two-thirds lateral fibula I - Base of first metatarsal & medial cuneiform | Peroneus longus |
| Peroneus longus, Peroneus brevis & Peroneus tertius perform this action | Eversion |
| Peroneus longus and Peroneus brevis perform this action. Peroneus tertius does not. | Plantar flexion |
| Of the peroneals, only tertius performs this action. | Dorsiflexion O - Lower two thirds of fibula I – 5th metatarsal |
| Primary muscle of ankle inversion | Tibialis anterior |
| O - Upper lateral tibia & interosseous membrane I - medial cuneiform & base of first metatarsal | Tibialis anterior |
| Extends the four lateral toes | Extensor digitorum longus |
| Extends the big toe | Extensor hallucis longus |
| O - upper anterior fibula I - phalanges of 4 lateral toes | Extensor digitorum longus |
| O - middle anterior fibula & interosseous membrane I - distal phalange of big toe | Extensor hallucis longus |
| Everting the foot & plantar flexing the ankle would lengthen this muscle | Tibialis anterior |
| O - calcaneus (plantar surface) I - middle phalanges of 4 lateral toes | Flexor digitorum brevis |
| O - calcaneus ( dorsal surface) I - 4 lateral toes via extensor digitorum longus tendons | Extensor digitorum brevis |
| What is the only "brevis" muscle of this chapter that crosses the ankle joint and is found in the leg? | Peroneus brevis |
| A membrane found between bones | Interosseous membrane |
| Heel bone | Calcaneus |
| Middle long bones of the foot | Metatarsals |

| Fibrocartilaginous discs attached to the tibial condyles | Menisci |
| This artery branches from the femoral artery to pass through the popliteal fossa at the back of the knee. | Popliteal |
| This nerve branches off of the sciatic nerve and can be accessible and vulnerable along the posterior surface of the head of the fibula. | Peroneal |
| This is a thick, superficial band of fascia stretching from the heel to the ball of the foot that is located between the skin and the muscles of the foot. | Plantar aponeurosis |
| These sacs of synovial fluid found around joints help protect the joint and its surrounding structures. | bursae |
