31 terms
Terms | Definitions |
|---|---|
 process | structure that sticks out (pan handle) |
| ramus | extension of bone that is usually at an angle (jaw bone) |
| trochanter | large rough to the touch projection (femur) |
| tuberosity | smaller rough to the touch bump |
| tubercle | small-medium sized rounded bump |
| crest | raised ridge of bone |
| line | raised ridge (lower and narrower than crest) |
| articulate | where bones meet |
| articular/auricular | describes areas where bones meet bones |
| head | rounded extremity (end) of typically long bone |
| neck | area just inferior to the head (surgical/anatomical) narrow connection btwn epiphysis and diaphysis |
| condyle | large swelling on either end of the ends of limb bones |
| facets | smooth flat oval shaped surfaces |
| demi-facets | small facet |
| trochlea | smooth rounded articulating surfaces on humerus |
| spine | sharp pointed extension of bone (type of process) |
| fossa | wide smooth shallow concave surface (depression where something fits) |
| foramen | a hole (nerves and vessels) |
| fissure | long crack or valley |
| sinus | small with small discrete hole, or a chamber w/in bone filled with air |
| origin | muscle begins (doesnt move) |
| insertion | muscle joins to move a bone |
| action | movement resulting from concentric contraction |
| prime mover | muscle mainly responsible for performing a listed movement |
| antagonist | PM responsible for the opposing movement of an action |
| synergists | assist the PM |
| types of tissue | epithelial,connective,muscle,neural |
| epithelial characteristics | avascular- regeneration- polarity (basal& apical membrane)- attached to basement membrane- closely bound (cell junctions) little extracellular materials btwn |
| connective tissue characteristics | comes from mesenchyme- different vascularity (bone-high/cartlidge/none)- lots of extracellular matrix |
| muscle characteristics | vascular- innercated- contractile protiens (actin/myosin) |
| nervous characteristics | generates/conducts electricity- no division/regeneration |
