(KAN-seh-lus) bone containing trabeculae; also known as spongy bone
containing trabeculae; also known as spongy bone
Chondrocyte
cartilage cell
compact bone
dense bone; contains structural units called Haversian systems
Diaphysis
shaft of the long bone
endochondral ossification
process by which bones are formed by replacement of cartilage models
Ephiphyses
end of the long bone,also the pineal body of the brain
myeloid tissue
red bone marrow, specialized type of soft, diffuse connective tissue, the site of hematopoeisis
Ossification
formed in cartilage
osteoblast
bone forming cell
osteoclast
bone absorbing cell
osteocyte
bone cell retired
name the 2 major types of connective tissue found in the skeleton system
bone and cartilage
name the 2 different types of bone tissue
compact and cancellous (spongy) bone
list the 6 structural components of a typical long bone that are visable to the naked eye
Diaphysis, epiphysis, articular cartilage, periosteum, medullary cavity, endosteum
identify the two principal chemical components of bone matrix
inorganic salts and organic matrix
identify 4 structures that form the osteon, or haversian canals
lamellae, lacunae, canalculi, and haversian canals
lamellae
concentric, cylander shaped layers of calcified matrix
Lacunae
small spaces containing tissue fluid in which bone cells are located between hard layers of lamellae
Canaliculi
ultrasmall canals radiating in all directions from the lacunae & connecting them to each other & to the Haversian canal
Haversian canal
extends lengthwise through the center of each osteon and contains blood vessels and lymphatic vessels
name the transverse canals that connect blood vessels between adjacent haversian systems
volkmann
name the needlelike spicules present in cancellous bone
trabeculae
name the 3 major types of bone cells
osteoblast, osteoclast, osteocytes
name the 2 types of bone marrow
red and yellow
what are the 5 functions of bone
support, protection, moovement, mineral storage and hematopoeisis
Identify the 2 types of bone formation
intramembrous and endochondral
name 3 specialized types of carilage
hyaline elastic fibrocartilage
identify the primary type of cartilage
chondrocyte
list the 2 mechanisms of cartilage growth
interstitial cartilage cells divide & secrete addtl matrix. appositional chondrocytes in the perichondrium divide & secrete matrix
periosteum
outside most important for survival of bone contains blood vessels. covers the bone
osteons
permit delivery of nutrients & removal of waste products
describe exocrine and endocrine glands
exocrine discharge into ducts and endocrine glands directly into the blood fluid
which tissue lines body cavities and protects body surfaces
epitheal
another name for skeletal muscle is
striated voluntary,
where does blood enter the bone
at the midpoint the diaphysis
what is the most common cartilage
hyaline
