Section 1

Question Answer
The more motor units of a muscle that are activtated, thestronger the contraction
skeletal muscles are attatched to bones or connective tissue bytendons and aponeurosis
Not correct (muslces) removal of acetycholine causes fibers to contract
muslces are arranged in functional groups with opposing actionsagonist and antagonist
skeletal muscle fiber contains many threadlike contractile elementsmyofibrilis
motor neuron and all muscle fibers that it controls constitutemotor unit
movable attatchment of a muscleinsertion
contractile unit of myofibril lies between 2 successive Z linessacromere
muscle fibers of a skeletal muscle arranged in small groups are calledfascicles
