"The little finger side of the hand sets across the
end of the forearm at a sharper angle than does the
thumb side.
It is narrower and never wholly conceals the rest
of the hand.
The pisiform bone, or heel of the hand, is always
conspicuous on the lower side of the wrist.
To it attaches the flexor carpi ulnaris muscle,
corresponding with the tendon of Achilles.

1 Pisiform (pea-sgaped) bone.

2 Flexor carpi ulinaris.
