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)

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

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
