Questions and Answers
What is the purpose of reciprocal activation in muscle physiology?
What is the purpose of reciprocal activation in muscle physiology?
- To coordinate muscle movement and prevent muscle fatigue
- To enhance muscle endurance and delay the onset of muscle soreness
- To regulate muscle contraction and relaxation for efficient movement (correct)
- To induce muscle hypertrophy and increase muscle strength
What happens when a muscle fiber is depleted of energy supplies?
What happens when a muscle fiber is depleted of energy supplies?
- The muscle will exhibit increased strength in contraction
- The muscle will fail to relax between stimuli (correct)
- The muscle will experience complete tetanus
- The muscle will completely relax
What is the role of lactic acid in muscle physiology?
What is the role of lactic acid in muscle physiology?
- It directly triggers muscle contraction
- It enhances ATP production in muscle cells
- It competes with Mg2+ for binding to troponin (correct)
- It causes rigor mortis in the absence of ATP
