Final answer:
The intrinsic muscles of the hand can be divided into three groups: thenar muscles, hypothenar muscles, and intermediate muscles. The dorsal interossei muscles help to abduct the fingers away from the midline of the hand, while the palmar interossei muscles help to adduct the fingers towards the midline of the hand.
Step-by-step explanation:
The intrinsic muscles of the hand can be divided into three groups: thenar muscles, hypothenar muscles, and intermediate muscles. The intermediate muscles include the lumbricals, palmar interossei, and dorsal interossei. The dorsal interossei muscles help to abduct the fingers away from the midline of the hand, while the palmar interossei muscles help to adduct the fingers towards the midline of the hand.
