INTRODUCTION
ANATOMY IS THE BRANCH OF BIOLOGICAL SCIENCE WHICH DEALS WITH THE FORM AND STRUCTURE OF ORGANISMS. CLOSE CORELATION WITH PHYSIOLOGY, WHICH TREATS OF THE FUNCTIONS OF THE BODY.
NATURE SCIENCES
*ABIOLOGI (physis, mathematic)
*BIOLOGI : $ fisiology $ morphology: .anatomy phytotomy : plants zootomy : embryology hystology
ANATOMI
ANATEM (YUNANI): cutting apart or dissociation of part of the body
ANATOMY in the earlier phase of development anatomy was necessarily a purely descriptive science, based on such observation as were possible with unaided eyes and simple dissecting instruments – scalpel, forceps, and the like.
GENERAL ANATOMY GENERAL ANATOMY
• MACROSCOPIC ANATOMY ( GROSS ANATOMY)
• MICROSCOPIC ANATOMY ( HISTOLOGY = TISSUE SCIENCE)
THE DEVELOPMENT & GROWTH THE DEVELOPMENT & GROWTH OF THE ORGANISMOF THE ORGANISM
• EMBRYOLOGY : the earlier phase of development of organism during which the tissue and organ are formed: fertilisation – foetus - partus
• ONTOGENY: study of the development of the individual organism
• FILOGENY (ancestral history) : is constituted by the evolutionary changes which it has undergone, as disclosed by geological record.
ORGANISM AS THE OBJECT OF THE STUDY
*SPECIAL ANATOMY : is the description of the structure of a single or species : anthropotomy, kinotomy dan hippotomy* COMPARATIVE ANATOMY :is the description and comparison of the structure of animals

NOMENCLATURE (NAV, 1972)
Until 1895 there was no general agreement on the nomenclature of human or veterinary anatomy. Each nation had its own systemof terminology.
The first international Nomina Anatomica Veterinaria was published in 1968.
AGREEMENT IN THE N.A.V
1. Aside from a very limited number of exception, each anatomical concept should be designated by a single term.
Each term should be in Latin in the official list, but the anatomists of each country are free to translate the official Latin terms into the language of instruction.
3. each term should be as short and simple as possible.
4. The term should be easy to remember and should have, above all, instructive and discriptive value.
5. Structure that are closely related topographically should have similar names; exp: arteria femoralis, vena femoralis, nervus femoralis.
6. Differentiating adjectives should generally be opposites, as major and minor, superficial and profundus.
7. Term derived from proper names (eponyms) should not be used.
DESCRIPTIVE TERM IN LATIN
THIS TERM USE IN THE BODY Dorsal Ventral Cranial Caudal anal
dorsal
ventral
cranialcaudal
The terms cranialis and caudalis apply to to the neck, trunk, tail, and the limb as far distally as the end of the antebrachium and crus.
The terms dorsalis and palmaris are used on the manus, and dorsalis and plantaris on the pes.
On the head the term rostralis, caudalis, dorsalis and ventralis are preferred, with terms anterior, posterior, superior, and inferior used in few location, such as eye ball, eyelids,and inner ear.
Medialis and lateralis are used on the whole body, except that axialis and abaxialis designate the sides of the digits in domestics mammals other than the horse.

RADIOLOGY ANATOMY
X RAY was invented in 1895 by CONRAD ROENTGEN.
It useful for diagnosis, treatments and research.
To be proficient in radiographic interpretation, one must first have some knowledge of the anatomy of the region x-rayed.
Three elements in x-ray shadow
1.AIR : in mouth, nose, paranasal sinuses, trachea, lungs, stomach, small intestine of the nursing individual, colon, and rectum.
2. WATER: in the blood (large vessels) and blood filled organs, such as liver, spleen and kidneys, and the urine-filled bladder.
3. MINERALS:primary significance, the calcium found in bones. Bone has calcium content & high radiopacity
Developmental anatomy

- ectoderm : external layerskin & nerve
- endoderm: internal layer viscera - mesoderm: cells between external and
internal layers muscles&bone

THE AMOUNT of THE BONES
Every breed have different amountexamples: horse 205 bones
catlle 191 – 193 bones
chicken 160 bones
human 206 bones (old), 270 (
baby)
This condition is depend on: breed & age

DEVELOPMENT OF THE BONES(osteogenesis)
1.osteogenesis intramembranosa (desmalis = primer): mesenchym cells osteoblast osteocyt matrix become jelly & solid (osteoid) calcification punctum ossification.
2. osteogenesis intracartilagenosa (enchondralis = secundair):
it begin with cartilago: mesenchym cells chondroblast chondrocyt (fill according the length of the bone) ossification.
Osteoblast : cells that destroy the bone cells which already done in order to have good shape.
ossification center
DEVELOPMENT : interstitial development
( from the middle of the tissue) appostitional development
(from the lateral, usually from perichondrium or periosteum become mass bone)

Maturity 1. sex maturity : genital organ
already have their function properly. ♂: wet dreams & ♀: menstruation
2. body maturity : all the bones already done (don’t have any punctum ossification ossification has alredy finished means the growth stop.

Supporting of the bones
• Periosteum / endosteum: it can make a new layer outside and inside of
the bone
• Soft bone (cartilago): it useful for joints shock absorbens between 2 bones.
• Tendon, ligamentum: elastic tissue that fix between 2 bones or with muscles.
JOINTS BETWEEN BONES(juncturae ossium)• JOINTS = syndesmology• requirements: 1. articular surface 2. cartilago 3. capsula synoviale 4. ligamentum 5. discus and meniscus 6. marginal cartilago (labrum gleniodale, acetabulare)
