Science Bones Test

flat function: to protect internal organs. ex. rib,scapula,and sternum
long any bone that is longer than it is wide, almost any bone in the arms and legs. ex. ulna, femur Function: allows for movement and help support body
short any bone that is wider than it is long. ex. carpal, tarsals Function: small movements and weight bearing
Irregular bones with no specific shape. ex. mandible, vertebrae, patella-"sesmoid". Function: protection
cartilage makes up some body parts- ears and nose. found on the end of all bones and between every vertebrae. Acts like shock absorbers.
ligaments connects bones to other bones. tough connective tissue,very elastic
tendons links bones to muscles
synonial fluid liquid found in every joint that keeps them moving freely.
joint any place where 2 or more bones meet
Fixed joint does not allow for movement. ex. cranium, pelvis
movable joints any joint that allows for full movement. ex. appendicular skeleton (arms+legs)
partially movable joints allows for limited movement. axial skeleton (neck)
ball and socket allows for movement in all directions. ex. humerus/femur
hinge joint allows for movement in 2 directions. ex. elbow/knee
sliding/gliding allowing for movement in all directions bit limited. ex. carpals/tarsals
pivot allows for motion in 4 directions. ex. neck/vertebrae
voluntary muscle that is under conscious control
involuntary muscles not under conscious control
skeletal muscles attached to the bones for movement, work in pair. ex. biceps and triceps
flexor bends bone towards body
extensor bends bone away from body
smooth looks and acts smooth, all involuntary, makes up many internal organs or line organs. Keeps organs working 24/7
