–Answer diaphragm, external intercostals, internal inter- costals
–Answer a sheet of pearly-white fibrous tissue that takes the place of a tendon in sheetlike muscles having a wide area of attachment.
–Answer splenius capitis
–Answer muscle shortens because muscle tension exceeds load
–Answer Tension does not exceed load, length of muscle remains the same. Tension produced never exceeds resistance.
–Answer individual twitches cannot be detected
–Answer The brief contraction of all muscle fibers in a motor unit in response to a single action potential.
–Answer theory that actin filaments slide toward each other during muscle contraction, while the myosin filaments are still
–Answer electrical impulse to neuromuscular junction
