OROFACIAL ANATOMY, HISTOLOGY, &
EMBRYOLOGY TEST #1
Abnormalities - Answer -You must be thoroughly familiar with the NORMAL surface
anatomy of the head and neck so that you can recognize this.
Surface features provide: - Answer -landmarks for deeper anatomic structures (soft
tissues and bone)
Exam of surface features can provide: - Answer -Info about the health of deeper tissues
(soft tissues and bone)
Normal - Answer -Conforming with or constituting an accepted standard, model, or
pattern.
Normal Anatomic Variation - Answer -When considering surface anatomy, normal
encompasses a wide range of variation.
If a surface structure is bilaterally symmetrical, - Answer -It probably fits within the limits
of normal anatomic variation.
Frontal Eminence - Answer -Prominence of the forehead
Glabella - Answer -Elevated area between the eyebrows
Congenital disease - Answer -Present at birth (develops during the first year of life),
often caused by a genetic defect.
Acquired disease - Answer -Not present at birth (develops later in life), usually not
caused by a genetic defect
The External Ear - Answer -1. The most prominent feature of the temporal region,
2. Auricle-flap that collects sound,
3. Tragus-The flap of tissue anterior to the meatus.
Medial and Lateral Canthi - Answer -Inner and outer corners of the eye.
Sclera - Answer -The white area of the eyeball
Iris - Answer -The pigmented area of the eyeball
Pupil - Answer -The opening in the center of the iris
, Conjunctiva - Answer -The thin membrane covering the front of the eyeball (bulbar) and
lining the inside of the eyelid (palpebral)
Naison - Answer -the depression just below the glabella
Nasal Root - Answer -The distance between the medial canthi
Nasolabial Sulcus - Answer -The groove that extends from the ala to the corner of the
mouth
Broad Nasal Root - Answer -Increased distance between the eyes
Zygomatic Region - Answer -The area over the cheek (zygomatic arch).
Malar Eminence-The most prominent area of the cheek.
Buccal Region - Answer -The area adjacent to the inner cheek (buccal mucosa)
Lips - Answer -Most prominent feature of the oral region
Vermilion Border - Answer -Outline of the lips from the surrounding skin
Commissure - Answer -The corner of the mouth
Chin - Answer -The most prominent feature of the mental region
Mental Protuberance - Answer -Part of the mandible that forms the bony prominence of
the chin
Body - Answer -Horizontal portion of the mandible
Ramus - Answer -Vertical portion of the mandible
Condyle - Answer -Articulating part of the mandible (the mandibular part of the jaw
joint)
Alveolar Process - Answer -The bone that supports the teeth
Sternocleidomastoid muscle - Answer -Divides each side of the neck diagonally into an
anterior cervical triangle and a posterior cervical triangle
Lymph Nodes of the neck - Answer -1. they become enlarged in various conditions,
from trivial (minor infections) to life-threatening (cancer),
2. Numerous lymph nodes are located in the head and neck area (they are called
cervical lymph nodes)
Facial (Labial) - Answer -Structures closest to the lips
