Tibialis posterior muscle (3D)

The video tutorial explores the tibialis posterior muscle, starting with a beach scenario to introduce the topic. It covers the anatomy of the muscle, including its location and attachment points. The functions of the tibialis posterior, such as inversion, support of the medial arch, and plantar flexion, are discussed. The tutorial also addresses potential injuries, like flat foot and over-pronation, and concludes with a recap of the key points.

What is the primary focus of the introduction in the video?

• An overview of common injuries related to the tibialis posterior muscle

• A discussion on the anatomy of the tibialis posterior muscle

• A scenario illustrating the importance of the tibialis posterior muscle

• A detailed explanation of the tibialis posterior muscle's functions

Where does the tibialis posterior muscle originate?

• Posterior surface of the tibia and fibula

• Medial surface of the tibia

• Lateral surface of the fibula

• Anterior surface of the tibia

Which joint is primarily involved in the inversion of the foot?

• Metatarsophalangeal joint

• Intertarsal joints

• Subtalar joint

• Talocrural joint

What role does the tibialis posterior play when the foot is on the ground?

• It assists in dorsiflexion of the foot

• It stabilizes the lateral arch of the foot

• It supports the medial longitudinal arch during weight bearing

• It helps in lateral rotation of the foot

What can result from an injury to the tibialis posterior tendon?

• Increased arch height

• Stronger plantar flexion

• Enhanced foot flexibility

• Flat foot condition

Which function is the tibialis posterior not primarily responsible for?

• Supporting the medial arch

• Plantar flexion of the foot

• Inversion of the foot

• Dorsiflexion of the foot

What is the role of the tibialis posterior during plantar flexion?

• It is the main muscle responsible for plantar flexion

• It stabilizes the foot during plantar flexion

• It prevents plantar flexion

• It assists in dorsiflexion
