structure of a long bone
Each end of a long bone is an expanded part of the
epiphysis
bones protect
body structures
Bones form by replacing existing connective tissues in either
intramembranous or endochondral bones
how many bones are in the skull
22
total axial bones
80
coats the epiphysis
articular cartilage
hematopoiesis
blood cell formation
Once an ECM completely surrounds osteoblast it becomes an
osteocyte
skull bones are interlocked by
sutures
total appendicular bones
126
When a bone is done growing the growth plate becomes the
epiphyseal line
where does the color of red bone marrow come from
hemoglobin
most bones in the skeleton are
ENDOCHODRAL
8 interlocked bones make up the
cranium
the femur belongs to what skeleton
appendicular
Osteocytes form a unit called
osteon
In adults red marrow is found in
spongy bone
endochondral bones Develop in the fetus from
hyaline cartilage
how many bones make up the facial skeleton
14
how many bones are in the pectoral girdle
4
Every central canal has
blood vessels and nerve fibers
Low blood calcium cause osteoclasts to
break down bone tissue and release calcium salts
Long bone continues to lengthen until the epiphyseal plates
ossify
foramen magnum is where nerve fibers from the brain enter the
vertebral canal
the sternum and ribs make up the
thoracic cage
