Physiology of Muscles

What are the functions of the muscular system?

• Digestion and nutrient absorption
• Blood circulation and oxygen transport
• The functions of the muscular system include movement, maintaining posture, and heat production.
• Hormone production and regulation

What are the characteristics of muscles tissue

• Muscle tissue is only found in the heart.
• Muscle tissue is characterized by contractility, excitability, extensibility, elasticity, and is classified into skeletal, cardiac, and smooth types.
• Muscle tissue is primarily composed of nerve cells.
• Muscle tissue does not have the ability to contract.

What are the three types of muscular tissue

• Tendons, ligaments, cartilage
• Red muscle, white muscle, yellow muscle
• Voluntary muscle, involuntary muscle, reflex muscle
• Skeletal muscle, cardiac muscle, smooth muscle

____________ and _____ produce muscle contraction.

• Collagen and elastin
• Actin and myosin
• Calcium and potassium
• Glucose and oxygen

What two chemicals induce muscle contraction

• Potassium ions and creatine
• Calcium ions and ATP
• Sodium ions and glucose
• Magnesium ions and lactic acid

What is the chemical compound that allows the Actin to attach to the myosin head?

• Calcium ions
• ADP
• ATP
• Creatine phosphate

What is the name of the theory for muscle contraction

• Sliding filament theory
• Cross-bridge theory
• Tension theory
• Elasticity theory

What is the role of ATP in muscle contraction?

• ATP is a waste product of muscle contraction.
• ATP inhibits the interaction between actin and myosin.
• ATP is only needed for muscle relaxation.
• ATP is essential for muscle contraction as it provides the energy for the interaction between actin and myosin.

What two things cause muscle fatigue

• High levels of oxygen and low temperatures
• Dehydration and lack of sleep
• Excessive hydration and protein intake
• Lack of oxygen and ATP
