II. Divisions of anatomy from different method and purpose of study.
A. Gross Anatomy It is the study of macroscopic or gross structure visible to the naked eye. Systematic anatomy; Regional anatomy.
B. Microscopic Anatomy (histology) It is the study of minute structures requiring the use of the microscope.

C. Developmental Anatomy (embryology)
It is the study of the development of the
body from its beginning (fertilized ovum ) to maturity.
D. Applied Anatomy ( Practical or Surgical Anatomy ) It is usually concerned with observations of
human structures which are useful in medicine,
especially in the surgical technique, but also in
clinical diagnosis.

IV. Anatomical terminology A. Anatomical position For the purpose of description of various parts of body and their location, a body is assumed to be in erect position.
It is essential to learn the anatomical position because most of the directional terminology used in anatomy refers to the body in this position.

VI. Chemical composition and physical properties Bones are composed mostly of the organic material and the inorganic material. 1. Organic material --- It’s about 30 ~ 40 percent of the dry weight of the bone and is mainly collagen. --- It gives the bones resilience and toughness. 2. Inorganic material --- It’s about 60 ~ 70 percent and chiefly are calcium phosphate, calcium carbonate. --- It gives the bones hardness and rigidity.

Section 2 The general description of the arthrology
I. Definition of the arthrology
Arthrology treats of a connection between two or more bones or between bone and cartilage. The bones are connected together by the fibrous, cartilaginous or osseous tissues.
