1 Which specific protein filament is primarily responsible for the 'power stroke' during the sliding filament theory of muscle contraction?

A Tropomyosin
B Troponin
C Myosin

2 In the context of cardiac output, which hormone is the primary catecholamine released by the adrenal medulla to increase heart rate during acute exercise?

A Epinephrine
B Cortisol
C Aldosterone
D Glucagon

3 The 'Bohr Effect' describes the shift of the oxygen-hemoglobin dissociation curve to the right, which is primarily caused by which factor during intense exercise?

A Increased pH
B Decreased PCO2
C Decreased body temperature
D Increased hydrogen ion concentration

4 Which muscle fiber type is characterized by high mitochondrial density, high capillary density, and a high concentration of myoglobin?

A Type IIx
B Type I
C Type IIa
D Type IIb

5 What is the primary function of the Golgi tendon organ (GTO) in the human musculoskeletal system?

A Detecting muscle length
B Detecting muscle tension
C Initiating the stretch reflex
D Inhibiting antagonist muscles

6 During steady-state aerobic exercise, which metabolic pathway provides the majority of ATP for muscle contraction?

A Pacinian corpuscle
B Muscle spindle
C Meissner corpuscle
D Free nerve ending

10 In the Frank-Starling mechanism, an increase in end-diastolic volume leads to an increase in stroke volume primarily due to what change?
