Skeletal
| Question | Answer |
|---|---|
| hemopoietic tissue | can produce blood |
| pachyostotic bones | pachy: thick, density regulation, denser than water, marine animals to stay at 1 level of water |
| notocord | support, muscle attachment, elastic energy; pressurized cylinder surrounded by fibrous sheath; able to bend but not change shape |
| hydrostatic skeleton | not made from 4 tissues of skeletal system; notocord, tongue, octopus arms |
| biomineralization | the deposition of inorganic salts onto a preformed proteinicous network --> collagen, elastin, ground substance |
| aspidine | acellular bone (osteoblasts retreat), minority |
| head skeleton | braincase, includes gills |
| axial skeleton | vertebral column, sternum, paired & attached - ribs, dorsal and caudal fins |
| appendicular skeleton | paired appendages, pectoral and pelval fin, girdles |
| epitoxy | epi: on top of, toxy: touch; salt deposited onto collagen |
| blast | precursor cell |
| ameloblasts | ectodermally derived, congregate and form an enamel organ that lays down enamel, mutually inductive with odontoblasts |
| odontoblasts | neural crest ectoderm derived, produce dentine, lay down dentine and withdraw |
| ground substance | collage and elastin embed in it --> connective tissue, mucopolysaccharides |
| lacunae | spaces osteocyte bodies occupy |
| canaliculae | spaces osteocyte processes occupy |
| metaphysis a.k.a. epiphyseal plate | where shaft and end of bone meet |
| epiphyses | ends of bone |
| diaphysis | middle or shaft of bone |
| endochondral bone growth | at epiphyses, cartilage --> broken down by chondroclasts --> osteoblasts invade and form bone |
| intramembranous or perichondral bone growth | at diaphysis, collagen in dermis is scaffolding --> hydroxyapatite on top --> bone |
| woven bone | young bone, quickly and randomly laid down, enough support for infants |
| lamellar bone | parallel sheets of mature bone, layered, stronger, more resistant |
| Haversian system | birds, mammals, other amniotes; osteoclasts invade old bone, blood vessels invade tunnel, osteoblasts form concentric layers around vessel; columnar osteon; mostly long bones |
| compact bone | dense, outside of shaft |
| cancellous bone | trabecular, spongy, interior of ends of long bones |
| hyaline cartilage | smooth, glassy, homogeneous, ends of long bones --> template, larynx, tracheal rings |
| fibrocartilage | lots of collagen, resistant to compression, intervertebral disks, menisci of joints |
| elastic cartilate | lots of elastin fibers, shape forming areas (pinnae-ears, nose, epiglotis-throat) |
| cellular cartilage | embryonic, many cells in matrix, agnathans where replaces collagen in matrix |
| calcified cartilage | any type can become, biomineralized layer around core, chondrichthians, no osteocytes-not bone |
| arthrology | study of joints |
| ligament | connect bone to bone, store elastic energy |
| tendon | connect muscle to bone, inelastic |
| synarthroses | fused, almost no movement, sutures in skull, diaphysis and epiphyses |
| amphiarthroses | limited motion; symphesis: dental snake, pelvic; syndesmoses: forearm rotation |
| diarthroses | highly mobile, with capsule, ball and hinge, socket |
| scaling | size and its consequences, bigger --> change shape |
| isometry | geometric similarity, bigger --> don't change shape, rare in nature |
| allometry | allo: different, change in different proportions, follows elastic similarity, change shape to deal with forces, ex: length of bone doubles and width cubes |
