The fleshy projection of the palmar surface of the hand, which corresponds with the little finger, and is supported by the fifth metacarpal bone. This eminence is formed of four muscles: the Palmaris brevis, Adductor seu Flexor brevis minimi digiti, and Opponens minimi digiti. The name Hypothenar has also been given to different muscles of the hand. The Hypothenar minimi digiti of Riolan comprehended the Abductor, Flexor brevis and Opponens minimi digiti; and his muscle, Hypothenar pollicis, corresponded to the Abductor and a portion of the Flexor brevis pollicis. Winslow called the Adductor minimi digiti, muscle petit hypothenar ou hypothinar du petit doigt.
