from the ears across the face almost as far as the nearest corner of
the mouth.

This is one of the muscles of the head, neck, and face that is included
on the syllabus of many courses in Indian
Head Massage. As this is an increasingly popular therapy we have
added several revision pages that may be helpful to students of Indian
Head Massage. See for example, the page about Skeletal
Structures of the Head and Neck.
See the Revision page about Facial
Muscles to view the location
of the zygomaticus
major muscle.
Note that this page consists of an interactive (rather than a simply
labelled) diagram, so you'll have to test yourself by guessing which
muscle is the zygomaticus
major until you find the correct label. It's a
fun way to learn ! |
