Q1. What is the shape of the proximal articular surface of the navicular?
- Cylindrical
- Flat and nonarticular
- Convex
- Concave
Q2. How many principal distal facets does the navicular have for the cuneiforms?
- Three
- One
- Two
- Five
Q3. Which cuneiform articulates with the largest medial distal facet of the navicular?
- Cuboid
- Lateral cuneiform
- Medial cuneiform
- Intermediate cuneiform
Q4. Which ligament supports the head of the talus immediately inferior to the talonavicular region?
- Long plantar ligament only
- Plantar calcaneonavicular ligament
- Anterior talofibular ligament
- Calcaneofibular ligament
Q5. Why is the navicular tuberosity readily palpable?
- It is covered by the fibula
- It projects medially in the superficial medial midfoot
- It lies deep within the ankle mortise
- It is located on the plantar calcaneus
Q6. How does tibialis posterior help support the medial longitudinal arch through the navicular?
- It pulls only on the fifth metatarsal
- It acts only at the knee
- Its navicular insertion helps dynamically support the medial arch
- It inserts exclusively on the calcaneus
Q7. Which joint combines with the calcaneocuboid joint to form the transverse tarsal joint?
- Talonavicular joint
- Metatarsophalangeal joint
- Ankle joint
- First tarsometatarsal joint
Q8. Which bone may have a variable articulation with the lateral side of the navicular?
- Calcaneus
- Cuboid
- Fibula
- First metatarsal
Q9. What lies directly distal to the navicular in the medial column of the foot?
- Calcaneus
- Talus
- Cuneiform bones
- Proximal phalanges
Q10. Why is the navicular often described as a keystone region of the medial longitudinal arch?
- It forms the posterior heel
- It lies outside the weight-bearing foot
- It creates the lateral malleolus
- Its position links the talar head to the distal medial column near the arch summit
