Document Summary
Smooth muscle: contract the internal organs, peristalsis, vasoconstriction, bladder function, cardiac muscle, heart muscle. Involuntary striated muscle: myocardium: muscle tissue of the heart. Fast and slow twitch fibers: fast-twitch fibers: Fast contraction and fast fatigue: anaerobic, do not use oxygen, used briefly, require oxygen to recover, used more for power movements, typically lighter in color, less blood, less oxygen. Store carbohydrates (complex sugars) as energy: use glycogen for energy, by product of glycogen use is lactic acid, causes muscle fatigue and soreness, slow-twitch fibers, aerobic: use oxygen during movement. Simple movements: reflexes: quick automatic responses to stimuli. Sneeze: punch, complex movements, central pattern generators: mechanisms in the spinal cord and brain that produce rhythmic output of motor behaviors, walking, breathing, chewing. Swallowing: central pattern generators, automatized routine rhythmic movements, require minimal attention awareness, no sensory feedback, complex movements, fixed action patterns: stereotypical sequence of movements/behaviors, typical of a particular species, provoked by an environmental stimulus.
