Muskeln des Fußrückens

This tutorial explores the anatomy of the foot, focusing on two main muscles: the extensor digitorum brevis and the extensor hallucis brevis. It covers their origins, functions, and innervation by the nervus peroneus profundus. The tutorial highlights the dorsal and plantar regions of the foot, explaining the role of these muscles in toe movement and the formation of the dorsal aponeurosis. Additionally, it notes the absence of these muscles' influence on the little toe, which is instead affected by the extensor digitorum longus.

What are the two main regions of the foot discussed in the tutorial?

• Medial and lateral sides

• Superior and inferior sides

• Plantar and dorsal sides

• Anterior and posterior sides

Which nerve is responsible for the innervation of the two muscles discussed?

• Tibial nerve

• Femoral nerve

• Nervus peroneus profundus

• Sural nerve

Where does the extensor digitorum brevis muscle originate?

• Plantar surface of the foot

• Medial surface of the foot

• Dorsal and lateral surface of the heel

• Anterior surface of the tibia

What movement is caused by the extensor digitorum brevis muscle?

• Plantar flexion

• Eversion

• Dorsal extension

• Inversion

Which joints are involved in the movement caused by the extensor digitorum brevis muscle?

• Metatarsophalangeal joint and proximal interphalangeal joint

• Distal interphalangeal joint and talocrural joint

• Ankle joint and subtalar joint

What is the primary function of the extensor hallucis brevis muscle?

• Adduction of the big toe

• Abduction of the big toe

• Dorsal extension of the big toe

• Flexion of the big toe

Which muscle is responsible for lifting the little toe?
