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
4
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 MACROSCOPIC ANATOMY ( GROSS ANATOMY)
MICROSCOPIC ANATOMY ( HISTOLOGY = TISSUE SCIENCE)
6
THE DEVELOPMENT & GROWTH OF 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.
7
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.
11
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.
12
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.
13
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.
14
DESCRIPTIVE TERM IN LATIN
THIS TERM USE IN THE BODY Dorsal Ventral Cranial Caudal anal dorsal cranial caudal ventral
15
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.
16
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.
17
Axis LONGUM
18
Proximal - distal Proximal: the direction go up
Distal : the direction go down
19
Cranial/rostral - aboral
20
ANATOMICAL DESCRIPTION
dorsal cranial anal caudal CRANIAL ventral
21
This term only in the skull
Oral Apical Aboral Nuchal Anterior posterior Superior Inferior
22
Extremities (thoracic and pelvic limb)
Proximal Distal Dorsal Volar Palmar plantar Ulnar Radial fibular Tibial Lateral Medial Median Sagittal Transversal horizontal
23
Median: devided the body in the median plane
Plana median Median: devided the body in the median plane bilateral simetrical.
24
SAGITTAL Cutting the body in the paralel ways with the median plane.

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.
31
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
32
Developmental anatomy
FERTILISASI ZYGOTE (mitosis: cleavage) MORULA BLASTULA GASTRULA devide into 3: - ectoderm : external layerskin & nerve - endoderm: internal layer viscera - mesoderm: cells between external and internal layers muscles&bone
33
THE FUNCTION OF SKELETON
To support the body To give the body form To protect the soft and weak tissue As a passive locomotion As a place for attachment of the muscles To produce blood. As chemical reservoir agents: Ca & P
35
THE AMOUNT of THE BONES Every breed have different amount
examples: horse bones catlle – 193 bones chicken 160 bones human 206 bones (old), 270 ( baby) This condition is depend on: breed & age
36
POSITION of the SKELETON
Axial skeleton Appendix skeleton Visceral skeleton : example: os penis : dog & cat os cordis : sapi os glandis : cat os hyodeus: vertebrata
37
ACCORDING TO THE SHAPE OF THE BONES
OSSA LONGA OSSA PLANA OSSA BREVIA OSSA IRREGULARIA
38
OSSA LONGA (long bones)
39
Ossa plana (flat bones)
40
OSSA BREVIA (short bones)
41
OSSA IRREGULARIA
42
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.
43
ossification center DEVELOPMENT : interstitial development
( from the middle of the tissue) appostitional development (from the lateral, usually from perichondrium or periosteum become mass bone)
44
PUNCTUM OSSIFICATION VERTEBRATA post natal
group I horse none cattle none sheep none group II human rabbit dog cat pig Guinea pig
45
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.
46

51
SINUS :spaces within the compact substance instead of spongy bone, and marrow ossa pneumatica, the cavities(sinus) are lined with mucous membrane; they communicate indirectly with the external air SINUS
52
Phisik os longa capsula cartilago Osseous epiphysis epiphise plate
metaphisis
53
CHEMICAL & PHYSICALLY STRUCTURE
chemic: organic : anorganic 1:2 composition : gelatin ,30% calcium phosphat ,35% calcium carbonat ,85% magnesium phosphat ,05% natrium carbonat& clorida 3,45%
54
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.
55
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)
