The word "thenar" means fleshy mounds. There are two fleshy mounds located in the palmar surface of the hand. These thenar mounds are called the thenar eminence and the hypothenar eminence. The thenar eminence is the fleshy mound at the base of the thumb. The hypothenar eminence is the mound located at the base of the fifth digit (little finger).

The word "thenar" means fleshy mounds. There are two fleshy mounds located in the palmar surface of the hand. These thenar mounds are called the thenar eminence and the hypothenar eminence. The thenar eminence is the fleshy mound at the base of the thumb. The hypothenar eminence is the mound located at the base of the fifth digit (little finger). The muscles located in the thenar eminence function primarily to control the thumb. The muscles present in the hypothenar eminence will contract and manifest motion through the little finger.
The hypothenar eminence is made up of four muscles. The four muscles are
- The abductor digiti minimi muscle,
- The flexor digiti minimi brevis muscle,
- The opponens digiti minimi muscle, and
- The palmaris brevis muscle. These muscles contract and create specific movements to the little finger.
Origin[edit | edit source]
