Intrinsic muscles of the hand mnemonic

Hello!
A short post on intrinsic muscles of the hand :)

The intrinsic muscle groups are:
- Thenar
- Hypothenar
- Interossei muscles
- Lumbrical muscles

Mnemonic for thenar and hypothenar muscles - "All For One And One For All"

Thenar group:
A: Abductor pollicis brevis
F: Fexor pollicis brevis
O: Opponens pollicis

A: Adductor pollicis

Hypothenar muscles:
O: Opponens digiti minimi
F: Flexor digiti minimi
A: Abductor digiti minimi

All intrinsic muscles of the hand are innervated by ulnar nerve, except LOAF muscles which are innervated by median nerve.
L: 2 Lateral Lumbricals
O: Opponens pollicis
A: Abductor pollicis brevis
F: Fexor pollicis brevis

Oh and last mnemonic, PAD DAB
Palmar interossei ADduct
Dorsal interossei ABduct

That's all!
You can't always be strong, but you can always be brave.
