Tibialis anterior muscle (3D)

The video tutorial explores the tibialis anterior muscle, focusing on its anatomy, attachment sites, and functional roles. It highlights the importance of dorsiflexion and inversion in maintaining balance and proper foot positioning. The tutorial also discusses the muscle's role in supporting the medial longitudinal arch during weight-bearing activities. Key concepts include the anatomy of the tibialis anterior, its interaction with joints, and its functions in dorsiflexion and inversion.

What is the primary movement associated with squatting that involves the ankle joint?

• Plantarflexion

• Dorsiflexion

• Inversion

• Eversion

Which nerve is responsible for innervating the tibialis anterior muscle?

• Superficial fibular nerve

• Sural nerve

• Deep fibular nerve

• Tibial nerve

Where does the tibialis anterior muscle originate from?

• Medial condyle of the femur

• Lateral condyle of the tibia

• Posterior surface of the fibula

• Anterior surface of the fibula

What is the primary function of the tibialis anterior muscle during walking?

• Flexion of the knee

• Dorsiflexion of the foot

• Plantarflexion of the foot

• Eversion of the foot

During which phase of the gait cycle is dorsiflexion particularly important?

• Pre-swing

• Terminal stance

• Midstance

• Initial contact

What movement is also known as supination of the foot?

• Eversion

• Dorsiflexion

• Inversion

• Plantarflexion

How does the tibialis anterior muscle contribute to the medial longitudinal arch of the foot?

• By elevating it during running

• By flattening it during walking

• By rotating it during jumping

• By supporting it during weight-bearing activities
