Final answer:
The flexor muscles that move the fingers are mostly located in the intrinsic muscles of the hand, such as the thenar and hypothenar muscles.
Step-by-step explanation:
The flexor muscles that move the fingers are mostly located in the intrinsic muscles of the hand. These muscles allow for precise movements of the fingers, such as typing and writing.
The thenar muscles, located on the lateral part of the palm, include the abductor pollicis brevis, opponens pollicis, flexor pollicis brevis, and adductor pollicis. The hypothenar muscles, located on the medial part of the palm, include the abductor digiti minimi, flexor digiti minimi brevis, and opponens digiti minimi.
The intermediate muscles, located in the middle of the palm, are the lumbricals, palmar interossei, and dorsal interossei.
