OSTEOLOGY

OSTEOLOGY : is a science which learn about bones and their relation

Bones are connectedeachother term as: skeleton

  • Skeleton: is applied to the frame-work of hard structureswhich supports and protects the soft tissue of animals.
bones system and their relationship
Bones System and their relationship
  • FERTILISATION  ZYGOTE (mitosis: cleavage)  MORULA  BLASTULA  GASTRULA  divides into 3:

- ectoderm : external layer skin & nerve

- endoderm: inner layer viscera

- mesoderm: between ecto & endoderm 

muscles and bones.

function of the skeleton
FUNCTION OF THE SKELETON
  • SUPPORT THE BODY
  • MAKE THE SHAPE OF THE BODY
  • PROTECK WEAK ORGANS
  • PASSIVE MOVEMENT ORGAN
  • PLACE FOR FIXING MUSCLE
  • PLACE FOR PRODUCES BLOOD
  • RESERVOIR CHEMICAL AGENT: Ca & P

THE SKELETON MAY BE DIVIDED PRIMARY INTO THREE PARTS:

SKELETON/ AXIALIS

Collumnar Vertebralis

Cranium

Sternum

Costae, Pelvis

SKELETON APPENDICULARIS

Ossa Extremitas Cranialis et Caudalis

SKELETON VISCERALIS : consists of certain bones developed in the substance of some of the viscera or soft organ

Os. Vesali os Hyoideus

Os. Penis os Cordis

Os. Glandis

SKELETON AXIALIS

(1) Collumnar Vertebralis, composes of :

Ossa. Cranii,

Cervicalis, Thoracalis, Lumbalis,

Sacralis and Coccygealis

(2) Ossa Costae, Sternum, Clavicula, Scapula,Coxae

(os Coxae, composes of: Ossa pubic, ilium and ischiadicum)

skeleton appendicularis
SKELETON APPENDICULARIS

Extremitas Cranialis :

Ossa Humerus, Radius-Ulna, Carpal, Metacarpal, Phalangis/digitalis

Extremitas Caudalis :

Ossa Femuralis, Tibia-Fibula, Tarsal, Metatarsal, Phalangis/digitalis

according their bones shape
ACCORDING THEIR BONES SHAPE
  • Ossa Longa (lonng)
  • Ossa Plana (flat)
  • Ossa Brevia (short)
  • Ossa Irregularis (irregular)

the amount of the bones
THE AMOUNT OF THE BONES
  • Each breed have different amount
  • example: horse 205 bones

cattle 191 – 193 bones

chicken 160 boness

human 206 bones (old), 270 (young)

This condition is depended by breed(ras) and age.

development and growth of bone osteogenesis
DEVELOPMENT AND GROWTH OFBONE(osteogenesis)
  • 1.osteogenesis intramembranosa (desmalis = primer): cel-cel mesenchym osteoblast  osteocyt  matrix become gel & solid (osteoid)  calcification  punctum ossification.
  • 2. osteogenesis intracartilagenosa (enchondralis = secundair):

started by cartilage : cel2 mesenchym chondroblast chondrocyt (fit length) ossification.

Osteoblast : destroy bone layer in order to make the shape.

punctum ossification
Punctum ossification
  • DEVELOPMENT :
  • Interstitial development

( from the middle of tissue )

  • appostitional development

(fron the lateral, the tissue change in order to fix bone layer)

  • cattle 5-9 months 4-5 years
  • Sheep/goat 6 months 4-5 years
  • pig 3-4 months 4-7 years
  • Dog 8 months 1,5-2 year
bone structure
BONE STRUCTURE
  • Bone mainly compose of bone tissue, but as an organ, it have layer term as periosteum, endosteum, medulla ossium, blood vessels and nerves.
  • According to the architecture :

1. compact substance.

2. spongiosa substance

In the long bone have medullar cavity.

slide22
Periosteum: is a membrane which enclose superficial surface of bone, except at the part which is lined by cartilage.
  • Endosteum: is a thin fibrous membrane which enclose medullare cavity and big Haversian canal.
  • Medulla ossium: placed between spongiosum bone and medullar cavity in the long bone.

in the adult animals have 2 variation:

as red and yellow:

slide23
In the young animals only have red (medulla ossium rubra), although then a part has change to be yellow (medulla ossium flava)
  • Medulla ossium rubra contains several type characteristic cells and as an substansia to make blood.
  • Medulla ossium flava : contains fatty tissue.
blood vessels nerves
BLOOD VESSELS & NERVES
  • composes 2 artery : periosteal and medullaris
  • nutritional foramen : hole in bone for passing through blood vessels  give nutrition.
  • Nerves distribute together with blood vessels. nerve ending in the periosteum (corpuscle Vater-Pacini) may be as sensoris, and probably as connection with muscle sense.

physical strength of bone
Physical strength of bone
  • The bone of just death animal has yellowish white color.
  • If it dip or boil s and give a chemical agent to eliminate stainbecome white.
  • Berat jenis fresh mass bone: 1,9
  • The bone is hard & strong enough for pressure
  • Strength pressure 20.000 pound per suare inch, strength of pulling 15.000 lb/inch² which more strong than white oak trees.
chemical and physical properties of bone
CHEMICAL AND PHYSICAL PROPERTIES OF BONE
  • Dried bone consists of organic and in organic matter which ratio 1 : 2.
  • Removal of organic matter by heat does not change the general form, but reduces the weight about 1/3 and makes bone very fragile
  • Decalcification, not change the form and size, but renders it soft and pliable.
  • Organic matter (ossein) boils  gelatin.
chemical structure physic

Periosteum / endosteum:

has capability to make new bone layer

cartilage: its for elascity and pressure absorber joint between 2 bones.

Tendo, ligament: fixing tissue between bones or muscles.

Impressio : depression cause of pressure another organ.

Foramen : hole for passing blood vessels, nerves, etc.

canalis : long holelike a tube

Fissura : space/ space within bone.

Incissura : cracking bone.

Sinus : air spaces within the compact substance, this cavities term as sinuses, are lined with mucous membrane & they communicateindirectly with external air

joints syndesmology
JOINTS / SYNDESMOLOGY
  • Is formed by the union of two or more bones or cartilages by other tissue.
  • The uniting medium is chiefly fibrous fibrous tissue or cartilage, or a mixture of these.
  • Union of parts of the skeleton by muscles term as SYNSARCOSIS
classification
CLASSIFICATION
  • 1. Fibrous joint (synsarcosis): the segment are united by fibrous tissue, often term as fixed or immovable joints.
  • 2. cartilaginous joint (amphiarthrosis): the segment are united by fibrocartilages or hyaline cartilage, or combination of the two.
  • 3. synovial joint ( diarthrosis)
fibrous joints
FIBROUS JOINTS
  • 1. SUTURE: the adjacent bones are closely united by fibrous tissue – sutural ligament:- suture serrata: sutura interfrontal

- suture squamosa: between

temporal and parietal bones - sutura plana(harmonia): internasal suture

  • 2. SYNDESMOSIS: the uniting medium is white fibrous or elastic tussue or mixture: exp: metacarpal bones.
  • 3. GOMPHOSIS: implantation of the teeth
cartilaginous joints
CARTILAGINOUS JOINTS
  • 1. SYNCHONDROSIS (hyaline cartilage joints): it’s a temporary one, then the cartilage is converted into bone: epiphysis.
  • 2. SYMPHYSIS (fibrocartilaginous joints):

exp: symphysis pelvis , sternebrae.

joints between bones juncturae ossium
JOINTS BETWEEN BONES(juncturae ossium)
  • JOINTS = syndesmology (diarthrosis)
  • requirements:

1. articular surface

2. cartilago

3. capsula synoviale

4. ligamentum

5. discus and meniscus

6. marginal cartilago (labrum

gleniodale, acetabulare)

chemical physically structure
CHEMICAL & PHYSICALLY STRUCTURE
  • chemic: organic : an organic 1:2
  • composition :

gelatin 33,30%

calcium phosphat 57,35%

calcium carbonat 3,85%

magnesium phosphat 2,05%

natrium carbonat& clorida 3,45%

supporting of the bones
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 absorbers between 2 bones.
  • Tendon, ligament: elastic tissue that fix between 2 bones or with muscles.
