Muscles and Bones
Bones - Answer organs providing framework for body, protection of body and acts as
levers
Ligaments - Answer connective tissue attaches bone to bone over a joint and provides
stability
Muscles - Answer provide force for movement by contracting, work in antagonistic pairs
- one muscle contracts while other relaxes
Tendons - Answer connective tissue attaches muscle to bone
Nerves - Answer motor neurons cause muscle contractions proprioceptors motor joints
Joints - Answer articulations where two or more bones meet
Antagonistic pairs - Answer When a muscle contracts, one end of that muscle is
connected to a bone that is not designed to move. The other end of same muscle is
connected to a bone that is designed to move. Muscles work in pairs so that the
opposite movement of the bone can also occur. Muscles can only actively contract and
relax. CANNOT lengthen. One muscle bends at limb (flexor) one muscle straightens
joint (extensor)
Tricep - Answer extensor in elbow
Bicep - Answer flexor in elbow
Cartilaginous Joint - Answer joints in which the bones are attached by cartilage. These
joints allow for only a little movment, such as in the spine or ribs.
Immovable Fibrous Joints - Answer Bones are fixed together by fibrous tissue with no
movement
Synovial Joints - Answer Bone-bone joints where there is self-contained capsule area
containing lubricant called synovial fluid. Ends of bones within capsule are also coated
with cartilage in order reduce friction. Free movement across one or more planes
