The hypothenar muscles are a group of three muscles of the palm that control the motion of the little finger.
The three muscles are:[1]
Structure
The muscles of hypothenar eminence are from lateral to medial:
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]
