Chapter Review Muscles

1

• Chapter Review Muscles
• mineral that binds to troponin on actin filament
• energy molecule that binds to myosin during
  sliding filament
• made up of bundles of muscle fibers (cells)
• made up of actin and myosin filaments
• thick filament
• smallest functional unit of skeletal muscle
• bond or link between myosin and actin

2

• striated, multinucleated, voluntary muscle
• blocks myosin binding sites on the actin
• cytoplasm of muscle fibers
• visceral muscles, involuntary control
• make up myofibrils, examples include actin and
  myosin
• site where a neuron meets with muscle

3

• the area between two successive Z discs
• what causes muscle striations
• network within muscle cells that functions in
  calcium storage and release
• made up of bundles of fascicles
• muscle fibers (cells) are divided into smaller
  subunits known as
• anaerobic process of breaking down sugar into
  pyruvic acid and forming small quantities of ATP

4

• organelle in the cell that makes ATP
• what type of muscle fibers would be more
  prevalent in a marathon runner
• type of contraction in which tension develops but
  the load does not move (lifting heavy object)
• when ATP is not available to separate myosin
  cross bridges after death, what condition results
• muscular degenerative genetic disorder
• collective name of chemicals released by nervous
  system across a synaptic gap

5

• Tie Break Questions
• connective tissue surrounding outer muscle
• neurotransmitter released that attaches to
  sarcolemma and stimulates the sarcoplasmic
  reticulum to release calcium (spell correctly if
  tie)
• connective tissue surrounding individual
  fascicles
