2. The lips are outlined from the surrounding skin by a transition area called the
a. philtrum.
b. mucogingival junction.
c. mucocutaneous junction.
d. mandibular symphysis.
ANS: C
The vermilion zone of each lip has a darker appearance than the surrounding skin, with the lips outline
by a transition zone, the mucocutaneous junction. On the midline of the upper lip extending downward
vertical groove, the philtrum. The line of demarcation between the firmer and pinker attached gingiva a

a. temporomandibular joint.
b. infraorbital region.
c. mental region.
d. parotid gland.
ANS: A
Inferior to the zygomatic arch and just anterior to the external ear is the temporomandibular joint. The
face is located inferior to the orbital region and lateral to the nasal region. Farther laterally is the zygom

toward the middle part of the external ear. The chin is the major feature of the mental region of the face
mental region is the mandible, or lower jaw. The parotid is located irregularly from the zygomatic arch
of the lower jaw.
