Palmar interossei muscles

The video discusses the Palmer interossei muscles, which are three unipennate muscles located in the metacarpus. These muscles originate from the metacarpal bones of the index, ring, and little fingers, and their surfaces face the middle finger. They insert at the dorsal aponeurosis and the base of the proximal phalanx. The deep branch of the ulnar nerve supplies these muscles, which primarily function to adduct the fingers towards the middle finger. They also flex the metacarpophalangeal joints and extend the interphalangeal joints. The video introduces a mnemonic to remember their function: 'dab' for dorsals abduct and 'pad' for Palmers adduct. Additional resources for learning anatomy are provided by Kenhub.
