LAB Muscle physiology

recording of skeletal muscle contraction

electromyogram (EMG)

what is the EMG recording

measurement of action potentials propagated by the skeletal muscle fibers

used to measure the force generated during muscle fiber conrtation

dynamometer

single action potential leading to a muscle contraction is called

twitch

all of the muscle fibers innervated by a single motor neuron is called

motor unit

sustaining high rates repetitive contraction will lead to skeletal…

muscle fatigue

what does muscle fatigue result from

a faster rate of ATP depletion than generation by the skeletal muscle during exercise wha

what is ATP

adenosine triphosphate

what does muscle metabolism switch from to produce ATP

aerobic to anaerobic

what has important clinical relevance in allowing an assessment of fine motor skills, indication of arthritis and an assessment of hand injuries
