name 5 functions of the skeletal system
1. support
2. protection (ribs protect lungs, cranium protects brain..etc)

3. movement - muscles are anchored to bones.

4. storage - stores calium

5. hemopoesis - blood cell formation
name 4 types of bones
long, short, irregular, flat
name 6 parts of the bone
diaphysis, epihysis, periosteum, medullary cavity, articular cartilage, endosteum
2 main parts of a bone
epiphysis and diaphysis
the connective tissue covering the bone is called?
periosteum
what is the medullary cavity
the space between a bone
difference between compact and spongy bone
compact bone is hard and spongy bone is soft
what are the spacesin the spongy bone called
trabeculae
what covers the end os the epiphysis
atricular cartilage
where is the red bone barrow located
in the epiphysis
name the 2 layers of the periosteum
1. fibrous layer
2. osteogenic or cellular layer
NAME THE 2 WAYS BONE DEVELOPS
endochondral -(cartilage ossifies)
intramembranous - (connective tissue ossifies)
where are osteocytes found
in the lucunae ( spaces between the hard layers of lamaellae)
what are canaliculi
tiny passages that connect lacunae with each other and with the central canal in each harversian system.
what are cartilage cells called
chondrocytes
when does growth stop?
when the epiphyseal plate (cartilage between the epyphsis and diaphysis) is transformed into bone.
the blood vessels runnning from the outside to the inside of a bone is known as
periosteal vessels
how does boen grow in width
1. osteoblasts create new bone
2. osteoclasts eat the bone away
3.osteocytes maintain the existing bone
how dioes bone grow
chondroblasts forsm c artilage, bone starts to develop perichondrium, they secrete bone
name and explain 4 bone diseases
1. osteoarthritis - degeneration of the articular cartilage

2. osteoporosis - deterieration of the bone in mass and density

3. osteomalacia - softening of the bones due to loss of mineralization resulting from lack of vitamin d ( in children it is called rickets)

4. osteomyelitis - infection of bone marrow by stepococcal bacteria or virus.
sarah's formula
determine:
1. sex
2.age
3. ethnicity
4. height
how does bone heals itself
bone is broken,there is a blood clot, first the osteogenic layer starts makin cartilage (chondrophies the clot). cartilage buils up anf forms calus all around and the cartilage ossifies into bone callus.
