The diaphragm is made up of what type of muscle tissue
skeletal muscle tissue
the muscle cell is surrounded by a membrane called
which organelle produces most of the energy necessary for skeletal muscle cells to contract and relax
which organelles take up most of the volume of a skeletal muscle cell?
the chemical released by motor neurons that causes contraction of the sarcomere
small motor units are comprised of how many muscle fibers
three to twelve
a single motor neuron and all muscle fibers innervated is referred to as
a motor unit
what is referred to as the tension produced by a skeletal muscle to maintain body position without muscle contraction
Exercise increases the number and size of this structure resulting in muscle hypertrophy

approximately how many skeletal muscles are there in the human body
the bundle of muscle fibers and its associated connective tissue is referred to as
what are the contractile units of muscle
myofilaments include two filaments (thick and thin)
- thick - myosin
- thin - actin
