Musculus tibialis anterior

The video tutorial explains the tibialis anterior muscle, part of the extensor group in the lower leg. It details the muscle's location, origins, and structure, including its attachment points and tendon pathway. The innervation by the peroneal nerve and its functions, such as dorsal extension and inversion, are also covered.

Which group of muscles does the tibialis anterior belong to?

• Flexor group of the upper leg

• Extensor group of the lower leg

• Adductor group of the thigh

• Rotator group of the hip

What is the primary origin of the tibialis anterior muscle?

• Upper third of the fibula

• Medial tibial facies

• Upper two-thirds of the lateral tibial facies

• Lower third of the tibia

Where does the broad attachment tendon of the tibialis anterior muscle attach?

• Lateral base of the fifth metatarsal

• Dorsal surface of the talus

• Medial and plantar surface of the first metatarsal

• Lateral surface of the calcaneus

Which nerve is responsible for the innervation of the tibialis anterior muscle?

• Peroneal nerve per fundus

• Tibial nerve

• Femoral nerve

• Sciatic nerve

What is one of the functions of the tibialis anterior muscle?

• Plantar flexion of the foot

• Flexion of the knee
