- The sliding filament theory
- a This nervous system provides involuntary control over smooth muscle, cardiac muscle, and glands.
- b • Formation of cross bridges between actin and myosin filaments.
• Reduction in distance between z-lines or sarcomere "power stroke"
• ATP is required for muscle contraction
o Myosin ATPase breaks down ATP as fiber
- c Channels for K+ open and it leaves cell
- d the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
- e • Type I fibers
• Slow-Oxidative fibers
• Always Start first
5 Multiple choice questions
- o Muscle produces force but length increases
- surround entire muscle
- ability of muscles to produce force w/ increasing velocity. muscle force increases, velocity of contraction decreases
- neuromuscular junction
- 600 (40-50% body weight)
5 True/False questions
Connective Tissue → stabilizes and supports components of skeletal muscle
Surrounds muscle at each organization level.
tropomin 1 → Holds Actin
Fast Fibers (Type IIx) → • Fast-Twitch Fibers
• Fast- Glycolytic
The layer of connective tissue that surrounds the outside of the skeletal muscle is called the: → Actin and Myosin
Muscle Spindles → • Located within the skeletal muscle
• 2 functions: monitor stretch and length of muscle
• initiate a contraction when muscle is stretched
