- E.
Naviculocuneiform
Correct Answer
D. CuboideonavicularExplanation
The cuboideonavicular joint is not a synovial joint. Synovial joints are characterized by the presence of a synovial fluid-filled cavity between the articulating surfaces, allowing for smooth movement. The talocalcneal, talonavicular, calcaneocuboid, and naviculocuneiform joints are all synovial joints found in the foot. However, the cuboideonavicular joint is a fibrous joint, which means it is connected by fibrous tissue rather than a synovial cavity.Rate this question:

All the following muscles are participating in dynamic support of your foot arches EXCEPT
- A.
Tibialis anterior
- B.
Gastrocnemius
- C.
Flexor hallucis longus
- D.
Fibularis longus
- E.
Tibialis posterior
Correct Answer
B. GastrocnemiusExplanation
The gastrocnemius muscle is not participating in the dynamic support of the foot arches. The foot arches are primarily supported by the tibialis anterior, flexor hallucis longus, fibularis longus, and tibialis posterior muscles. The gastrocnemius muscle is responsible for plantarflexion of the foot, not for providing support to the arches.Rate this question:

Muscle that inverts your foot & dorsiflex your ankle?
- A.
Tibialis posterior M
- B.
Tibialis anterior M
- C.
Extensor digitorum longus M
- D.
Flexor hallucis longus M
- E.
Soleus M
Correct Answer
B. Tibialis anterior MExplanation
The tibialis anterior muscle is responsible for both inversion of the foot and dorsiflexion of the ankle. Inversion refers to the movement of the foot towards the midline of the body, while dorsiflexion refers to the movement of the foot towards the shin. The tibialis anterior muscle is located on the front of the lower leg and plays a crucial role in stabilizing the ankle and foot during walking and running.Rate this question:

- A.
Calcaneus
- B.
Talus
- C.
Navicular
- D.
Three metatarsals
- E.
Three cuneiforms
- F.
All the above
Correct Answer
F. All the aboveExplanation
The bones that maintain the medial longitudinal arch of the foot are the calcaneus, talus, navicular, three metatarsals, and three cuneiforms. These bones work together to provide support and stability to the arch, allowing for proper weight distribution and shock absorption during walking and running.Rate this question:

Nerve cause Plantarflex your foot & flex your knee
- A.
Common fibular N
- B.
Tibial N
- C.
Femoral N
- D.
Sural N
- E.
Saphenous N
Correct Answer
B. Tibial NExplanation
The tibial nerve is responsible for innervating the muscles that plantarflex the foot and flex the knee. It is a major branch of the sciatic nerve and provides motor and sensory innervation to the posterior compartment of the leg and foot. Plantarflexion is the movement of pointing the foot downwards, while knee flexion is the movement of bending the knee. Therefore, the tibial nerve is the correct answer as it is directly involved in these movements.Rate this question:
