Fibularis longus muscle (3D)

The video tutorial explores the fibularis longus muscle, detailing its anatomy, the joints it affects, and its key functions. It highlights the muscle's role in foot eversion, plantar flexion, and support of foot arches, emphasizing its importance in activities like running and walking. The tutorial also discusses potential issues arising from damage to the muscle or nerve, such as over-supination and reduced shock absorption.

What is the primary function of the fibularis longus muscle during running?

• To extend the hip

• To flex the toes

• To lift the heel off the ground

• To stabilize the knee joint

Which nerve is responsible for the innervation of the fibularis longus muscle?

• Deep fibular nerve

• Tibial nerve

• Sural nerve

• Superficial fibular nerve

The fibularis longus muscle primarily affects which joint for foot eversion?

• Knee joint

• Hip joint

• Subtalar joint

• Ankle joint

What is the role of the fibularis longus in preventing excessive inversion of the foot?

• It flexes the toes

• It stabilizes the knee

• It supports the medial arch

• It returns the foot to a neutral position

How does the fibularis longus assist in plantar flexion?

• By extending the knee

• By drawing the heel upwards

• By lifting the toes

• By stabilizing the ankle

Which arches of the foot does the fibularis longus help support?

• Medial and lateral arches

• Transverse and lateral longitudinal arches

• Transverse and medial longitudinal arches

• Lateral and medial longitudinal arches

What condition can result from damage to the fibularis longus tendon?

• Overpronation

• High arches

• Flat feet

• Over supination
