saddle
articulating surfaces are saddle shaped; one surface is concave, the other surface is convex
sinus
bone cavity, filled with air and lined with mucous membrane; depressions and openings
head
bony expansion carried on a narrow neck; projections that help form joints
process
bony prominence; projections that are site of muscle and ligament attachment
circular fascicle arrangement
fascicles arranged in concentric rings
sesamoid bone example
patella
epicondyle
raised area on or above a condyle; projections that are site of muscle and ligament attachment
foramen
round or oval opening through a bone; depressions and openings for passage of vessels and nerves
condyle
rounded articular projection; projections that help form joints
parallel fascicle arrangement
run same way to the long axis of the muscle
fossa
shallow basinlike depression in a bone, often serving as an articular surface; depressions and openings
spine
sharp, slender, often pointed projection; projections that are site of muscle and ligament attachment
tubercle
small rounded projection or process; projections that are site of muscle and ligament attachment
facet
smooth, nearly flat articular surface; projections that help form joints
sesamoid bone definition
specialized type of short bone that forms within tendons
fixator
stabilizes the origin of a prime mover; muscle that limits movement of bone or joint
pivot
synovial joint; a rounded bone fits into a sleeve (concave bone plus a ligament)
hinge
synovial joint; a rounded or cylindrical bone fits into a concave surface on the other bone
plane
synovial joint; flat or slightly curved bones
ball-and-socket
the ball-shaped head of one bone fits into the cuplike depression of the other bone
trochanter
very large, blunt, irregularly shaped process (only examples on femur); projections that are site of muscle and ligament attachment
crest
Narrow ridge of bone; usually prominent; projections that are site of muscle and ligament attachment
tuberosity
Large rounded projection; may be roughened. projections that are Site of muscle and ligament attachment.

flat bone examples
cranial bones and sternum
short bone definition
cube shaped and contain more spongey bone than compact bone
Flat bone definition
generally thin, with two wafer-like layers of compact bone sandwiching a thicker layer of spongy bone between them
long bone example
humerus, femur, or phalanges
origin joint movement
immovable bone during muscle movement
long bone definition
longer than they are wide
insertion joint movement
moveable bone during muscle movement
agonist
muscles that are most responsible for producing a particular movement
antagonist
muscles that oppose or reverse a movement
fissure
narrow, slitlike opening; depressions and openings for passage of vessels and nerves
sutural bone definition
tiny bones between cranial bones
Irregular bone definition
unusually shaped bone that doesn't fall under the other categories
irregular bone examples
vertebra
