Skeletal : _____ muscles are usually attached to bones.
Smooth : _____ muscles are named because they don't have striations.
Cardiac : _____ muscles are found in just one place in the body - the heart.
Muscle fibers : A usually voluntary muscle made up of elongated, multinucleated, transversely striated muscle fibers, having principally bony attachments.
Myofibrils : A contractile fibril of skeletal muscle, composed mainly of actin and myosin.
Myosin : A thick filament of a protein that each myofibril contains.
Actin : A think filament of a protein that each myofibril contains.
Sarcomere : The basic mechanical unit that makes muscles work.
Neuromuscular : Pertaining to nerves and muscles, or to the relationship between them.
Acetylcholine : When a motor neuron is stimulate, its axon terminals release a neurotransmitter called _____.
Tendons : Tough connective tissues by which bones are joined by.
Contract : Skeletal muscles generate force and produce movement by pulling on body parts as they _____.
Muscle : There are three different types of _____ tissue: skeletal, smooth, and cardiac.
Neurons : Motor ____ connect the central nervous system to skeletal muscle cells.
Fulcrum : The joint functions as a ____ - the fixed point around which the lever moves.
