signal of interest must be converted into an analog voltage is done by a ____
transducer
process: voltage usually varies continuously over time and is monitored by the hardware which can modify it by amplification and filtering
signal conditioning
signal conditioning zeroing
involves the removal of an unwanted steady offset voltage from a transducer's output
frequency
the number of occurrences of a repeating event per unit time
amplitude
height of the wave from baseline to crest
waveform
shape and form of a signal
wavelength
length from the crest of one peak to the crest of the next peak
skeletal muscle cells
make up about 40% of the cell mass of the body
skeletal muscles so the majority of
the work for locomotion and support of the animal skeleton
each muscle is made up of individual ____ organized in fascicles.
muscle fibers (muscle cells)
to produce mechanical energy in directed movements,
muscles to the chemical energy stored in ATP
skeletal muscle structure- connective tissue sheaths of skeletal muscle: epimysium, perimysium, and endomysium
disease of muscle are rare and mostly inherited but,
trauma to muscle is very common
upper motor neuron lesions
loss of muscle function as a consequence of strokes damaging neutons in the brain
skeletal muscle is ____
consciously controlled and therefore voluntary, can rapidly contract but tires rapidly.
excitability
all muscle cell membranes have an electric charge differential which can be changed upon stimulation (such as through neurotransmitter binding) to ultimately produce an intracellular muscle response
