Mineral Storage
The solid ECM is made from:
crystallized calcium and phosphates
the type of bones tht includes femur, hemorus, radius, fibula, etc:
long bones
The cavity(s) with red marrow:
epiphyses, metaphyses
outer layer of dense irregular connective tissue and inner layer containing bone cells:
-osteoprogenitors
-osteoblasts
(protects all bones)
the cells included in endosteum:
osteoprogenitors
osteoblasts
osteoclasts
This mineral is used heavily in the brain & muscles:
calcium
The type of bone that includes tarsals and carpals:
short bones
The cavity with yellow marrow:
diaphysis
This is located where bones form joints
articular cartilage
the cells inside the lacunae:
osteocytes
In this calcium condition, bone cells called osteoclasts & osteocytes are stimulated to release calcium from bone tissue.
The type of bone that includes ribs and sternum
flat bones
Each long bone has ALL of these:
2 epiphyses
2 metaphyses
1 diaphysis
cortex
medullary cavity
made from 3 lamellations, and principally supported by structures called osteons:
compact bone
the cells included in periosteum:
osteoprogenitors,
osteoblasts
this happens when the bones does not make enough matrix:
osteoporosis (results in fragile bones) (caused by age/hormonal change)
The type of bone that includes mandible, maxilla, sacrum, coccyx:
irregular
Cortex vs medulla:
cortex: outer
medulla: inner (middle)
the location that ostocytes occupy within the lamellations: (inside compact bone):
lacunae
(they "live in lacunae houses"... has canals that glucose can get thro to get to cells)
the principle effectors of bone remodeling:
osteocytes
this occurs when the bone is mlaformed:
ex: Rickets in children, caused by inadequate absorption of calcium.
The type of bone that includes patella, hallux, & pollex:
sesamoid bones
one major difference in the MARROW of these areas of a bone:
metaphyses, epiphyses, diaphysis
metaphyses & epiphyses: red bone marrow!
diaphysis: yellow marrow
endosteum
(endo is key part of word)
the function of these cells:
osteoprogenitors:
osteoclasts:
osteoblasts:
- "stem cell" of the bone, can initiate remodeling by osteoclasts or osteoblasts.
-cells that break down the bone.
-cells that build up bone.
