Anatomical Terms of
Direction and Position
• Created for communicating the
direction and relative positions of
body structures.
• Most have Latin or Greek roots.
• Some are eponyms
(commemorative names).
Anatomical Landmarks
• Based on figures in the
anatomical position.
• Maybe lying down supine (face
up) or prone (face down).
• Example: brachium (arm);
brachialis muscle; brachial artery.
Anatomical Regions
• Describe general area of
interest or injury.
• Example: The Quadrants of
the Abdominopelvic Region
Some Anatomical Directions
• Superior and Inferior
• Anterior and Posterior
• Dorsal and Ventral
• Proximal and Distal
• Medial and Lateral
Some Anatomical Directions
• Superficial- at, near or
closer to the body surface.
• Deep- farther from the body
surface.
Sectional Anatomy
• Describe three-dimensional structures.
• Sectional Planes:
Transverse Planes- divide the body into
superior/inferior sections.
Frontal Planes - divide the body into
anterior and posterior sections.
Sagittal Planes-divide the body into left and
right sections. Exactly equal halvesMidsagittal Section
