Question 5

Which of the following may be involved in the disruption of the vermilion zone and may make it hard to determine the exact location of its mucocutaneous junction between the lips and the surrounding skin?

Accepted Answer

Disruption of the vermilion zone may make it hard to determine the exact location of its mucocutaneous junction between the lips and the surrounding skin.These changes may be due to scar tissue from past traumatic incidents,developmental disturbances,or cellular changes in the tissue such as occur with solar damage.These changes may also represent a more serious condition such as cancer; however,this can be verified only with tissue biopsy and microscopic examination.If this change is part of a past history of a cleft lip,this also needs to be noted in the patient record because of its impact on dental care.

The bone underlying the mental region is the mandible,or lower jaw.On the lateral aspect of the mandible,the stout,flat plate of the ramus (plural,rami) extends upward and backward from the body of the mandible on each side.At the anterior border of the ramus is a thin,sharp margin that terminates in the coronoid process.The midline of the mandible is marked by the mandibular symphysis.The main part of the anterior border of the ramus forms a concave forward curve,the coronoid notch.

Question 11

The main feature of the _____ region of the face is the external nose.

Accepted Answer

The main feature of the nasal region of the face is the external nose.The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region.Farther laterally is the zygomatic region,which overlies the bony support for the cheek,the zygomatic arch.The temporal region is on the lateral side of the head at the temple.

Question 12

Just inferior to the zygomatic arch and just anterior to the external ear is the:

Accepted Answer

Inferior to the zygomatic arch and just anterior to the external ear is the temporomandibular joint.The infraorbital region of the face is located inferior to the orbital region and lateral to the nasal region.Farther laterally is the zygomatic region,which overlies the bony support for the cheek,the zygomatic arch.The zygomatic arch extends from just below the lateral margin of the eye toward the middle part of the external ear.The chin is the major feature of the mental region of the face; the bone underlying the mental region is the mandible,or lower jaw.The parotid is located irregularly from the zygomatic arch down to the posterior border of the lower jaw.

Question 13

Which of the following facial features is located laterally to each naris?

Accepted Answer

The nares are separated by the midline nasal septum.The nares are also bounded laterally by winglike cartilaginous structures,each ala (plural,alae) of the nose.In the orbital region of the face,the eyeball and all its supporting structures are contained in the orbit of the skull,the bony eye socket.On the midline of the upper lip extending downward from the nasal septum is a vertical groove,the philtrum.

Accepted Answer

The vermilion zone of each lip has a darker appearance than the surrounding skin,with the lips outlined from the surrounding skin by a transition zone,the mucocutaneous junction.On the midline of the upper lip extending downward from the nasal septum is a vertical groove,the philtrum.The line of demarcation between the firmer and pinker attached gingiva and the movable and redder alveolar mucosa is the scallop-shaped mucogingival junction.The midline of the mandible is marked by the mandibular symphysis.

Question 16

Which of the following structures can be palpated in the anterior midline of the neck?
