CHAPTER 1:
INTRODUCTION

Anatomy: the science of the structure and function of the body
Clinical Anatomy: the study of the macroscopic structure and function of the body as it relates to the

practice of medicine and other health science

Basic Anatomy: the study of the minimal amount of anatomy consistent with the understanding of the
overall structure and function of the body

I. DESCRIPTIVE ANATOMIC TERMS
A. TERMS RELATED TO POSITION

Anatomic Position: standing erect, upper limbs by the sides, face and palms directed forward
1. Median Sagittal Plane: Vertical plane passing through the center of the body

 Division: right and left halves
 Paramedian: parallel planes situated to one side of the median plane
 Medial (adj.): structure situated nearer to the median plane of the body
 Lateral (adj.): structure situated farther from the median plane of the body

2. Coronal Planes: imaginary vertical planes at right angles to the median plane
3. Horizontal/ Traverse Planes: planes at right angles to both the median and coronal plane

 Anterior (adj.): front of the body vs. Posterior (adj.): back of the body
o Hand: Palmar vs. Dorsal
o Foot: Plantar vs. Dorsal

 Proximal vs. Distal: describe relative distances
 Superficial vs. Deep: describe relative distances of structures from the surface of the body
 Superior (adj.): upper end of the body vs. Inferior (adj.): lower end of the body
 Internal vs. External: describe relative distances of structures from the organ/cavity’s center
 Ipsilateral (adj.): Same side of the body vs. Contralateral (adj.): opposite sides of the body
 Supine (adj.): body lying backwards vs. Prone (adj.): body lying face down

B. TERMS RELATED TO MOVEMENT

Joint: site where two or more bones come together

1. Movement in the Sagittal Plane
a. Flexion: usually an anterior movement (except for the knee)

Lateral Flexion: movement of the trunk in the coronal plane
b. Extension: usually a posterior movement of straightening the joint

2. Movement in the Coronal Plane
a. Abduction: movement of limb away from the midline
b. Adduction: movement of limb toward the body

3. Other movements:
a. Rotation: movement of the body around its long axis

Medial Rotation: movement in the anterior surface of the part facing medially
Pronation of the Forearm: medial rotation in which the palm faces posteriorly

Lateral Rotation: movement in the anterior surface of the part facing laterally
Supination of the Forearm: lateral rotation in which the palm faces anteriorly

b. Circumduction: combination of flexion + extension + abduction + adduction
c. Movement of the Jaw (temporomandibular joints):

Protraction: to move forward
Retraction: to move backward

d. Movement of the Foot:
Inversion: sole faces the medial direction
Eversion: sole faces the lateral direction
