The hypothenar muscles form the hypothenar eminence – a muscular protrusion on the medial side of the palm, at the base of the little finger. These muscles are similar to the thenar muscles in both name and organisation.

Extrinsic/intrinsic muscles (flexor, extensor) in hands & fingers: how many are there, list of names with anatomy, innervation, action, mnemonics, & labeled diagram
The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors.
There are 34 muscles in each of your hands. Healthcare providers categorize them into groups, including: Thenar muscles: Muscles that control your thumb.

The muscles of the hand can be broken down into three main regions: the thenar (lateral or thumb side of the palm), hypothenar (medial or little finger side of the palm) and intermediate (middle of the hand) muscles.
Most of the small muscles that work the thumb and pinky finger start on the carpal bones. These muscles connect in ways that allow the hand to grip and hold. Two muscles allow the thumb to move across the palm of the hand, an important function called thumb opposition.
The thenar muscles consist of three short muscles located on the lateral (radial) aspect of the hand. These muscles include the, abductor pollicis brevis, flexor pollicis brevis and opponens pollicis.
