what
is the hallux?
key:
* differs from human
not a muscle, but a relevant structure
remember that knowing origin, insertion,
and function - action of each muscle & muscle group is
(a) required, and
(b) helpful for
identification and remembering which is which
YOU MUST KNOW THE
RELEVANT BONES, TOO!!
