Fußmuskulatur

The tutorial provides a comprehensive overview of the muscles in the foot, detailing their origins, functions, and innervations. It covers the flexor digitorum brevis, quadratus plantae, lumbrical, interossei, small toe lodge, big toe lodge, and back of the foot muscles, explaining their roles in foot movement and stability.

Which muscle is primarily responsible for flexing the second to fifth toes at the base and middle joints?

• Abductor hallucis

• Quadratus plantae

• Extensor digitorum brevis

• Flexor digitorum brevis

What is the main function of the quadratus plantae muscle?

• Extension of the second to fourth toes

• Flexion of the big toe

• Support of the flexor digitorum longus

• Abduction of the little toe

Which nerve supplies the first lumbrical muscle?

• Medial plantar nerve

• Tibial nerve

• Lateral plantar nerve

• Common fibular nerve

The interossei plantaris muscles are responsible for which movement?

• Dorsal extension

• Adduction

• Plantar flexion

• Abduction
