muscle

what are the three types of muscle tissue
cardiac, smooth and skeletal
why do muscle cells have lots of mitochondria
mitochondria release lots of energy; this means that muscle cells can contract
why do muscle cells have lots of glucose
glucose is a store of energy; this means it can be used to release energy for contractions
why do muscles cells have protein filament
they slide past each other; this means that the shape of each muscle cell can be shortened and contract; means that the whole muscle can contract
antagonistic pairs is when one muscle contracts the other muscle relaxes or lengthens
an agonist is when the muscle contracting
an antagonist is when the muscle relaxing
flexion is bending a joint; angle decreases
extension is straightening a joint; angle increases
