Chapter 01: Introduction to Head and Neck Anatomy
MULTIPLE CHOICE
1. Which surface of the body is visualized by the clinician when performing an extraoral
examination of the patient’s eyes?
a. Anterior
b. Posterior
c. Superior
d. Lateral
ANS: A
Feedback
A The patient’s eyes are visualized on the anterior surface of the patient’s body.
B The patient’s eyes would NOT be easily visualized on the posterior of the
patient’s body.
C The patient’s eyes would NOT be easily visualized on the superior surface of the
patient’s body.
D The patient’s eyes would NOT be easily visualized on the lateral surface of the
patient’s body.

2. Which of the following is CORRECT concerning the sagittal plane of the body?
a. Parallel to the median plane
b. Parallel to the frontal plane
c. Parallel to the horizontal plane
d. Parallel to the coronal plane
ANS: A
Feedback
A A sagittal plane is parallel to the median plane.
B A sagittal plane is NOT parallel to the frontal plane but perpendicular.
C A horizontal plane is perpendicular to the median plane. A sagittal plane is
parallel to the median plane. Thus a horizontal plane is perpendicular to a
sagittal plane.
D A sagittal plane is NOT parallel to the coronal plane but perpendicular.

3. When a patient is in anatomic position, what is the surface of the palms of the hand
considered?
a. Anterior
b. Lateral
c. Medial

d. Posterior
ANS: A
Feedback
A The palms of the hands in anatomic position are facing toward the front and are
anterior (or ventral).
B The palms of the hands in anatomic position are NOT facing lateral or away
from the median plane but are facing toward the front and are anterior (or
ventral).
C The palms of the hands in anatomic position are NOT facing medial or toward
the median plane but are facing toward the front and are anterior (or ventral).
D The palms of the hands in anatomic position are NOT facing toward the
posterior or back of the body but are facing toward the front and are anterior (or
ventral).

4. What is the anatomic relationship of the right arm to the left leg?
a. Sagittal
b. Contralateral
c. Ipsilateral
d. Midsagittal
ANS: B
Feedback
A The two legs are contralateral to each other. Sagittal describes a plane of division
of the body created by an imaginary plane parallel to the median plane.
B Contralateral structures are located on the opposite side of the body, which is the
anatomic relationship of the right arm to the left leg.
C Ipsilateral refers to structures on the same side of the body; in contrast, the two
legs are contralateral to each other and thus are located on the opposite side of
the body.
D The two legs are contralateral to each other. Midsagittal describes a plane that
divides the body into right and left halves.

a. Anterior
b. External
c. Deep
d. Superficial

a. Deep
b. Medial
c. Inferior
d. Superior
ANS: D
Feedback
A The shoulders are superior to the hips.
B The shoulders are superior to the hips.
C The shoulders are superior to the hips.
D The shoulders are superior to or closer to the head than the hips.

7. Which of the following is meant by the term “ventral”?
a. Back of an area of the body
b. Front of an area of the body
c. Inner side of an area of the body
d. Outer side of an area of the body
ANS: B
Feedback
A The back of an area of the body is referred to as the posterior surface.
B The front of an area of the body is referred to as the ventral surface.
C The inner side of an area of the body, away from the body surface, is referred to
as deep.
D The outside of an area of the body, toward the surface, is referred to as
superficial.
