The hypothenar muscles are a group of three muscles of the palm that control the motion of the little finger.

Carpal tunnel and thenar and hypothenar eminences

The three muscles are:^[1]

Abductor digiti minimi
Flexor digiti minimi brevis
Opponens digiti minimi

Structure

The muscles of hypothenar eminence are from lateral to medial:

Opponens digiti minimi
Flexor digiti minimi brevis
Abductor digiti minimi

The intrinsic muscles of hand can be remembered using the mnemonic, "A OF A OF A" for, Abductor pollicis brevis, Opponens pollicis, Flexor pollicis brevis, Adductor pollicis (thenar muscles), Opponens digiti minimi, Flexor digiti minimi, Abductor digiti minimi (Hypothenar muscles).^[2]

Clinical significance

"Hypothenar atrophy" is associated with the lesion of the ulnar nerve, which supplies the three hypothenar muscles.

Hypothenar hammer syndrome is a vascular occlusion of this region.^[3]

Cortical excitability differences in hand muscles follow a split-hand pattern in healthy controls.

Menon P1, Kiernan MC, Vucic S.
Muscle & nerve.Muscle Nerve.2014 Jun;49(6):836-44. doi: 10.1002/mus.24072. Epub 2014 May 2.
Introduction: Differences in cortical and axonal excitability may underlie preferential atrophy of abductor pollicis brevis (APB) and first dorsal interosseous (FDI) in amyotrophic lateral sclerosis, termed the split-hand. Consequently, this study aimed to determine whether differences in excitabili
