Ch 6 Skeletal Tissue

from marieb textbook skeletal tissue

begins at each epiphysis secondary ossification
canal like passage meatus
bone deposition osteoblast
fracture at epiphyseal plate epiphyseal fracture
hyaline cartilage endochondrial
rounded articular projection condyle
blood clot forms hematoma
2 words for bone development ossification, osteogenesis
bone fragments into many pieces comminuted
thin plates trabeculae
thin and flat ex. sternum flat bone
very little blood formation in long bones
connect lacunae to each other canaliculi
covers bone (external) supplies bone with blood vessels, nerves periosteum
fracture at skull depression
control of remodeling mechanical, hormonal
stimulated by growth hormone longitudinal growth
increase in bone diameter appositional growth
what is the diaphysis composed of? compact bone
what is articular cartilage composed of? hyaline cartilage
spaces for bone cells lacunae
breaks incompletely greenstick fracture
groove furrow
2 types of tissue cartilage, bone
functions of bones storage, protection, movement, support
longer than wide ex. femur long bone
complex ex. vertebrae irregular
expanded ends of a long bone epiphysis
unit of bone structure osteon
site of most blood cell production flat and irregular bones
small rounded projections tubercle
large rounded projection tuberosity
raised area on or above condyle epicondyle
bony expansion on narrowed neck head
narrow ridge of a bone crest
shallow basin like depression fossa
weakening of bones increased removal of calcium osteoporosis
crushed compression
cavity in bone filled with air line with mucous membrane sinus
bone resorption osteoclast
broken ends of bone protrude through soft tissue increased risk of infection compound fracture
types of bone tissue compact, spongy
within a tendon ex. patella sesamoid
shaft of a long bone diaphysis
what does the epiphysis articulate with? other bones to form a joint
run crossways where blood vessels and nerves enter bone volkmann's canals
splint that connect ends of bones fibrocartilage callus
very large, blunt irregular shaped proccess trochanter
replace clot w/ collagen fibers fibroblast
flat bone formation within a fibrous membrane ex. sternum, skull, scapula intramembranous
smooth nearly flat articular projection facet
narrow ridge of bone less prominent than crest line
what does the articular cartilage do? covers ends of bones provides smooth surface for movement
armlike bar of bone ramus
mineral salts deposited around collagen fibers for hardness hydroxyapatites
twisting spiral fracture
breaks cleanly ends don't penetrate skin simple fracture
blood cell production (red marrow) hematopoiesis
b/t skull bones ex sutures wormian
round or oval opening through a bone foramen
what is the epiphysis composed of? inner spongy, outer compact
characteristics of short, flat, irregular bones sandwich like, thin layer of compact bone on top and bottom, inner spongy
central hollow core of osteon haversian canal
concentric rings with bone matrix lamellae
begins @center of diaphysis primary ossification
narrow slit like opening fissure
lines internal bone surface contains osteoclasts endosteum
sharp, slender, often pointed spine
what does the diaphysis surround? medullary cavity (yellow marrow)
maintenance of matrix osteocytes
2 components of embryonic skeleton fibrous membranes, hyaline cartilage
cube like ex. carpals short bones
junction of diaphysis and epiphysis epiphyseal line
