Competency 1: Introductory concepts and terminology in
Human Anatomy
• Upon successful completion of this laboratory, the students
should be able to apply the basic concepts and terminology of
Human Anatomy by:
•
– Demonstrating the anatomical position.
– Listing the directional terminology for the human body.
– Identifying the human anatomical regions.
– Recognizing the different body cavities.
– Competency 2:
– Identifying and describing the different parts of human cells
and their functions.

Introduction.
• Anatomy is considered the oldest medical science.
• There are Egyptian drawings from 1600 BCE illustrating basic
knowledge about blood vessels.
• The word anatomy has Greek roots as well as physiology.
• Anatomy means “ a cutting open”

Anatomy and Physiology
• Anatomy is the study of internal and external structures of the
body and the physical relationship among them.
• Physiology is the study of how living organisms perform their
functions.

Anatomy and Physiology are closely
integrated
• Anatomical information provides clues about functions, and
physiological mechanisms can be explained only in terms of the
underlying anatomy.

Medical terminology
• It is the special language that involves the use of word roots,
prefixes, suffixes and combine them to create terms related to
the body in health and disease.

Sectional planes
•
Transverse or horizontal: it separates
superior and inferior portions of the body
(cross section).
•
Sagittal: it separates right and left
portions.
Midsagittal: it divides the body in
equal right and left.
Parasagittal: It divides the body in
unequal right and left.
•
•
•
Frontal or coronal: it divides the body in
anterior and posterior.

Abdominopelvic quadrants and regions.
• Abdominopelvic quadrants:
They are formed by a pair of imaginary
perpendicular lines that intersect at the
umbilicus (navel).They are 4 regions.
They are preferred by Clinicians.
• Abdominopelvic regions: there
are 9 abdominopelvic regions. They are
preferred by Anatomists
