Слайд 1Introduction
Human skeleton initially cartilages and fibrous membranes
Hyaline cartilage

is the most abundant cartilage
By age 25 the skeleton

is completely hardened

206 bones make up the adult skeleton (20% of body mass)
80 bones of the axial skeleton
126 bones of the appendicular skeleton

Introduction Human skeleton initially cartilages and fibrous membranes Hyaline cartilage is the most abundant cartilage By age

Slide 5.4a
Long bones
Typically longer than wide
Have a shaft

with heads at both ends
Contain mostly compact bone
Examples: Femur, humerus

Слайд 10Microscopic Structure
Bone cells are called osteocytes
in a lacuna

Osteocytes transport nutrients and wastes by cellular processes in canaliculi

The extracellular matrix of bone is largely collagen and inorganic salts
Collagen gives bone resilience & strength
Inorganic salts make bone hard

Слайд 15Bone Development and Growth
Parts of the skeletal system begin

to develop during the first few weeks of prenatal development

Bones replace existing connective tissue in one of two ways:
As intramembranous bones
As endchondral bones
Bone Development  and Growth Parts of the skeletal system begin to develop during the first few

Слайд 16Intramembranous Bones

Слайд 23Skeletal Organization
The actual number of bones in the human

skeleton varies from person to person

Typically there are about

206 bones

For convenience the skeleton is divided into the:
Axial skeleton
Appendicular skeleton
