Final answer:
The 'flexor digiti minimi longus' does not correspond to a standard muscle name in human anatomy, but there are related muscles such as the flexor digiti minimi brevis in the hypothenar group that flex the little finger, and the flexor digitorum superficialis and flexor digitorum profundus in the forearm that flex the fingers.
Step-by-step explanation:
The muscle you are asking about, the flexor digiti minimi longus, seems to be named incorrectly as there is no widely recognized muscle in human anatomy with this exact name. However, I can provide information on similar-sounding muscles related to the movement of the little finger. The flexor digiti minimi brevis is a muscle that flexes the little finger and is one of the hypothenar muscles located in the palm of the hand. Regarding muscles in the forearm that control finger movement, there are the flexor digitorum superficialis and flexor digitorum profundus, which are situated in the anterior compartment of the forearm and involved in the flexion of the fingers and the hand at the wrist.
The hypothenar muscles, which act on the little finger, also include the abductor digiti minimi and the opponens digiti minimi. These muscles, along with the flexor digiti minimi brevis, form the hypothenar eminence, which is the rounded contour of the little finger's base. The intrinsic hand muscles such as the thenar and hypothenar muscles originate and insert within the hand, allowing for precise movements like typing and writing.
