Terminology
I don't need much in the way of terminology to describe the
poses here - because of the illustrations.
The digits, named
Inside, outside, open, closed
I'll sometimes refer to opening and closing joints.
Opening joints refers to the effect of activating the
extensors - and closing a joint is the result of activating
its flexors.
It is sometimes useful to refer to the inside and
outside of joints.
The inside of joints is where more sweat glands are
located. It is either hairless - or sometimes very
hairy. The outside of joints tends to be more bony
and is often covered with wrinkled skin.
The main place where this terminology can seem unorthodox is
when dealing with the ankle - the achillies heel represents
the inside of the ankle joint. Consider the analogy
between the ankle and the wrist and this might make more sense.
The knuckles, numbered
Anatomy
A knowledge of the hand's bone and muscle structure is of
some use in knowing what stretches are potentially useful -
but a detailed anatomy lesson is currently beyond my scope
here.
