Muskeln der Mittelhand

The video tutorial provides an in-depth look at the intrinsic muscles of the hand, focusing on the metacarpal muscles. It covers three main groups: Interossei Palmaris, Interossei Dorsalis, and Lumbrical muscles. Each section details the origins, approaches, and innervation of these muscles, highlighting their unique features and differences. The tutorial emphasizes the importance of understanding these muscles for anatomical studies and practical applications.

What distinguishes intrinsic hand muscles from extrinsic ones?

• Intrinsic muscles originate on the forearm.

• Intrinsic muscles have long tendons.

• Intrinsic muscles lie directly on the hand bones.

• Intrinsic muscles are located in the foot.

Which muscle group is highlighted in green in the illustrations?

• Interossei Palmaris

• Flexor Digitorum

• Interossei Dorsalis

• Lumbrical Muscles

Where does the first Interossei Palmaris muscle originate?

• On the ulnar side of the fourth metacarpal bone

• On the radial side of the fourth metacarpal bone

• On the ulnar side of the second metacarpal bone

• On the radial side of the second metacarpal bone

What is the innervation source for the Interossei Palmaris muscles?

• Median nerve

• Radial nerve

• Deep branch of the ulnar nerve

• Superficial branch of the ulnar nerve

How many muscles make up the Interossei Dorsalis group?

• Four

• Three

• Five

• Two

Which muscle is the strongest among the Interossei Dorsalis?

• Fourth Interossei Dorsalis

• Third Interossei Dorsalis

• Second Interossei Dorsalis

• First Interossei Dorsalis

What is unique about the origin of the Lumbrical muscles?

• They originate from tendons.

• They originate from bones.

• They originate from ligaments.

• They originate from skin.

Which nerve supplies the first and second Lumbrical muscles?

• Axillary nerve

• Median nerve

• Radial nerve

• Ulnar nerve

What is the shape of the Lumbrical muscles compared to?

• A fish

• A snake

• A bird

• A worm

What is the main focus of the tutorial?

• Muscles of the forearm

• Muscles of the foot

• Muscles of the metacarpus

• Muscles of the shoulder
