Function Of Bones

Definition

 

A.    Support

B.     Protection

C.    Levers – movement

D.    Storage

E.     Blood cell production – hematopoiesis

 

 

 

Term
bone or osseous tissue contains...
Definition

 

 

 

 

1.      mineral salts (calcium phosphate and calcium carbonate)         Ca(PO4)2 + (OH)2  and  Ca CO2. Hydroxyapatites (67% of bone).

 

2.      Collagenous fibers (33% of bone) – salts are deposited on collagenous fibers

 

 

 

 

 

Term
Diaphysis
Definition
shaft of long portion of bone
Term
Epiphysis
Definition

 

 

1.      extremities or ends of bone.  (metaphysic – region of mature bone where the diaphysis joins the epiphysis.

 

Term

 

Articular cartilage

Definition

 

 

hyaline cartilage covering epiphysis

Term
Periosteum
Definition

 

dense white, fibrous covering of bone

a. fibrous layer (outer) containing blood vessels, lymphatic vessels and nerves.

b. Osteogenic layer (inner) contains elastic fibers, blood vessels, and osteoblasts (forms new bone during growth or repait)

 

 

Term
Medullary or marrow cavity
Definition
space within the diaphysis
Term
Endosteum
Definition

1.      layer of osteoblasts that line the medullary cavity and contain scattered osteoclasts (may play a role in removal of bone).

 

Term

 

Compact or dense bone

 

Definition

a.      Volkmann’s canals

             b.      Haversian system or osteon

(1 )lamellae

(2 )lacunae

(3 )canaliculi

 

Term
Spongy or cancellous bone
Definition

a.  trabeculae

 

  b.  red marrow

 

Term

 

Ossification –

 

Definition
 process by which bones form in the body
Term
The “skeleton” or human embryo is composed of
Definition

either fibrous membranes or hyaline cartilage

 

Term
when does Ossification begins?
Definition
6th week of embryonic life and continues throughout adulthood
Term

Two kinds of bone formation

 

Definition

   a.      Intramembranous ossification – formation of bone directly on or within the fibrous membranes

 

b.      Endochondral ossification – formation of bone in cartilage,

 

Term
osteoblasts
Definition

Osteoblasts will form bone tissue by intramembranous or endochondral ossification.
