3.1 Head
Temporomandibular joint
(Figs 3.15, 3.18, 3.19)
The temporomandibular joint is located inferior to the zygo-
matic arch and anterior to the tragus of the ear. Its movement can
easily be palpated by gently opening and closing the mouth.
ST-7is located in a depression anterior to the joint and
directly inferior to the zygomatic arch. This depression is situ-
ated in the mandibular incisure, which is formed by the coronoid
and condylar processes of the mandible. By opening the mouth,
the palpating finger resting on ST-7is ‘lifted’ out of the
depression by the condyloid process sliding anteriorly.
