MPP Week 5: Post-Break Quiz

The longitudinal arches of the foot primarily function to:

• Reduce hip strain

• Assist with balance on one foot

• Act as a lever for pushing off the ground

• Absorb shock and distribute body weight during movement

Answer explanation

The longitudinal arches of the foot are crucial for absorbing shock and distributing body weight during movement, which helps maintain stability and reduces the risk of injury.

The fibula primarily contributes to which of the following functions?

• Load-bearing during walking

• Formation of the knee joint

• Lateral ankle stabilization

• Articulation with the patella

Answer explanation

The fibula primarily provides lateral ankle stabilization, supporting the ankle joint and preventing excessive side-to-side movement. It does not bear significant load during walking or form the knee joint.

Which joint allows for dorsiflexion and plantarflexion of the foot?

• Subtalar joint

• Interphalangeal joint

• Talocrural joint

• Calcaneocuboid joint

Answer explanation

The talocrural joint, also known as the ankle joint, is responsible for dorsiflexion (lifting the foot) and plantarflexion (pointing the foot down). The other joints listed do not facilitate these specific movements.
