Abduction vs. Adduction of the Fingers, Clinical Tests and an Easy Way to Remember

The video tutorial covers the concepts of finger abduction and adduction, explaining the muscle groups responsible for these movements: the dorsal interossei for abduction and the palmar interossei for adduction. A mnemonic, DABPAD, is introduced to help remember these muscle groups. The tutorial also demonstrates clinical tests to assess the strength of these muscles and the function of the ulnar nerve, which supplies them. The video concludes with a summary of the tests and a call to action for viewers to like and subscribe.

What is the primary function of the dorsal interossei muscles?

• To extend the fingers

• To abduct the fingers

• To flex the fingers

• To adduct the fingers

Which mnemonic helps remember the muscle groups responsible for finger movements?

• PADAB

• PADDA

• DABPAD

• ABPAD

What is the purpose of the clinical test involving resistance against finger abduction?

• To test the flexor muscles of the hand

• To assess the strength of the dorsal interossei muscles

• To evaluate the function of the radial nerve

• To assess the strength of the palmar interossei muscles

Which nerve supplies both the dorsal and palmar interossei muscles?

• Musculocutaneous nerve

• Radial nerve

• Ulnar nerve

• Median nerve

What is the function of the palmar interossei muscles?

• To extend the fingers

• To flex the fingers

• To abduct the fingers
