1. Chapter 1
Organization of human body

2. LEARNING OBJECTIVES At the end of the lecture you should be able to
Define Anatomy and classify Anatomy.
Differentiate between macroscopic, microscopic and developmental Anatomy.
Explain histological and embryological terms.

3. LECTURE OUTLINE Anatomy definition. Subdivisions of Anatomy
Macroscopic anatomy
Regional anatomy
Systemic anatomy
Surface anatomy

4. LECTURE OUTLINE Microscopic anatomy Epithelial tissue Cytology
Histology
Basic human body tissues
Epithelial tissue
Connective tissue
Muscular tissue
Nervous tissue

5. LECTURE OUTLINE Developmental anatomy (Embryology) Definition
Embryological terms
Ovulation
Fertilization
Pregnancy
Conceptus
Gestation
Embryonic period
Fetal period

6. Anatomy Describes the structures of the body: What they are made of
Anatomy is the study of structure of the human body and the relationship of its part to each other
Describes the structures of the body:
What they are made of
Where they are located
Associated structures

7. Topics for Anatomy Anatomy has many subdivisions
Gross or macroscopic anatomy
Microscopic anatomy
Developmental anatomy

8. MACROSCOPIC ANATOMY
UNIT 5
CHAPTER 28

9. Gross or macroscopic anatomy is the study of the large body structures visible to the naked eye.
3 types
Regional anatomy
Systemic anatomy
Surface anatomy

10. 1. Regional anatomy
All the structures (muscles,bones nerves etc) in the particular region of the body are examined at the same time.

11. 2. Systemic anatomy
Body structure is studied system by system

12. 3. Surface anatomy
The study of the internal structures as they relate to the overlying skin surface

13. MICROSCOPIC ANATOMY CYTOLOGY &HISTOLOGY
UNIT 5
CHAPTER 28

14. MICROSCOPIC ANATOMY Microscopic anatomy
study of the structures of the body under the microscope.
Cytology -microscopic study of the cells
Histology -microscopic study of the tissues

15. Histology
The study of microscopic anatomy of tissues of plants and animals.
BASIC HUMAN BODY TISSUES
Human body tissues are classified into four basic types.
Epithelial tissue
Connective tissue
Muscular tissue
Nervous tissue

16. Histology
Epithelium
Covers body surfaces, lines organs and cavities.

17. Histology
MUSCULAR TISSUE
Histologically there are three types of muscular tissues, all responsible for different kind of movements.

18. Histology It is the main component of the nervous system
NERVOUS TISSUE
It is the main component of the nervous system
It is composed of neurons, and neuroglia cells

19. Histology

21. Histology Connective tissue
Binding and packing material – mechanical strength, elasticity.
Other types of support – carrying nerves and blood vessels
Wide variety of functions.

22. DEVELOPMENTAL ANATOMY (EMBRYOLOGY)
UNIT 5
CHAPTER 28

23. Embryology DEFINITION
Study of the origin and development of an organism.

24. Embryology Embryological terms Ovulation
Release of the egg from the ovaries(female reproductive organs)
Fertilization
Union of the sperm(male reproductive cell) with the egg (female reproductive cell) to form a zygote.

25. Embryology
Pregnancy The term pregnancy refers to the events that occurs from the time of fertilization to the birth of the new born. Conceptus The developing offspring in the pregnant woman is called conceptus. Gestation The time during which the development of the fetus occurs.

26. Embryology Embryonic period from fertilization to 8 weeks.
All major organs of the fetus are formed.

27. Embryology
Fetal period is from the 9th week until the birth. During this period organs of the conceptus grow larger and become more complex.
