1. Muscles MUSCLES http://www.youtube.com/watch?v=3FGZvFZdVbkhttp://www.youtube.com/watch?v=3FGZvFZdVbk (“pick things up”)

2. Generate motion Generate force Some muscle tissues generate heat

3. Voluntary; Response to Somatic Motor Neuron w/ACh (AP), Striated. Movement of skeleton and skin. (fastest) Involuntary*; Autonomic, Important for homeostasis, wide variety (6: H. sapiens), Act as integrating centers in response to endocrine system, Not striated. Lines GI, walls of viscera [stomach, urinary bladder & GI]. (slowest) Involuntary*, Autonomic, Shares BOTH smooth & skeletal muscle, striated, electrically linked. Under sympathetic, parasympathetic & hormonal control. Specialized muscle for the heart. (intermediate)

7. This sliding filament mechanism can only occur when there are sufficient calcium ions (Ca 2+ ) and sufficient ATP is also available.ATP

9. Slow: Aerobic for continuous movement. Less likely to fatigue. Fast: IIa: Anaerobic & aerobic. IIb: Anaerobic and fastest contraction of all muscle fibers. Highest rate of fatigue.

11. Check your Standards for Study 05.02 Describe the four characteristics of muscle tissue. (elasticity, excitability [irritability], extensibility, flexibility) 05.03 Contrast the general location, microscopic appearance, control, and functions of the three specific types of muscle tissue. (skeletal, smooth, cardiac) 05.04 Contrast thick and thin myofilaments. 05.05 Describe the sliding-filament theory of muscle contraction. 05.06 Describe what occurs at the neuromuscular junction. 05.07 Define the terms “origin” and “insertion.” 05.08 Explain the role of prime movers (agonists), antagonists, synergists, and fixators.
