This document provides an introduction to human anatomy. It defines anatomy as the study of the structure of the human body and its close relationship to physiology, which is the study of function. Anatomy is divided into gross anatomy, which can be seen with the naked eye, and microscopic anatomy, which requires a microscope. The human body is organized from cells to tissues to organs to organ systems to the whole organism. The document lists the 11 major organ systems and provides a brief overview of anatomical directions, planes, sections, body cavities, and body quadrants.

1. Human Anatomy
Introduction

2. What is Anatomy?
• Study of the STRUCTURE of the Human
Body
• Closely related to PHYSIOLOGY!
• Physiology is the study of the FUNCTION
of the human body

3. Divisions of Anatomy
• Gross Anatomy
• Structures that can be
seen with the eye
• Muscles, bones,
various organs
• Microscopic Anatomy
• Structures that cannot
be seen with the eye
• Need to use a
microscope
• Cytology = study of
cells
• Histology = study of
tissues

4. What are you made of ?

5. Ways to Study Anatomy
• Regional Anatomy – study one region of
the body at a time and learn everything
about the region
• Systemic Anatomy – study one body
system at a time. This is the approach we
will use in this course

6. Anatomical Organization
• Cells
• Tissues
• Organs
• Organ Systems
• Organism

8. Organ Systems
• 1. Integument
• 2. Skeletal
• 3. Muscular
• 4. Nervous
• 5. Endocrine
• 6. Cardiovascular
• 7. Lymphatic
• 8. Respiratory
• 9. Digestive
• 10. Urinary
• 11. Reproductive

12. Four-footed body directions

13. Planes and Sections
• Sagittal section – divides the body into
right and left sides
– Mid-sagittal section = straight down the center
of the body
• Frontal section – divides the body into
front and back sides
• Transverse (cross) section – cut straight
across the body

14. Planes and Sections

15. Body Cavities

16. Body Cavities

18. Body Quadrants
• Right Upper Quadrant (RUQ)
• Left Upper Quadrant (LUQ)
• Right Lower Quadrant (RLQ)
• Left Lower Quadrant (LLQ)
