The small bones that make up the backbone
strong connective tissue that holds bones together in movable joints
A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together.
Hard, dense bone tissue that is beneath the outer membrane of a bone.
Layer of bone tissue having many small spaces and found just inside the layer of compact bone.
The soft connective tissue that fills the internal spaces in bone.
A muscle that is not under conscious control
A muscle that is under conscious control
A muscle that is attached to the bones of the skeleton and provides the force that moves the bones. (voluntary, fast reaction time, tire quickly)
The muscle tissue found only in the heart. (involuntary, fast reaction time, long endurance)
Involuntary muscle found inside many internal organs of the body. Ex: intestines (involuntary, slow reaction time, long endurance)
Strong connective tissue that attaches muscles to bone (the 'paperclips' in our model!)
Allows forward and backward motion (ex elbows and knees)
ball and socket joint
A convex "ball" that fits into a concave "cup". Allows the greatest range of motion. (ex: hips and shoulders)
Allows one bone to rotate around another (ex: your neck)
Allows one bone to slide over another (ex: wrists and ankles)
Bones that are connected in a way that allows movement! 4 different types we learned about (hinge, ball and socket, pivot and sliding)
