front 1 signal of interest must be converted into an analog voltage is done by a ____ | back 1 transducer |
front 2 process: voltage usually varies continuously over time and is monitored by the hardware which can modify it by amplification and filtering | back 2 signal conditioning |
front 3 signal conditioning zeroing | back 3 involves the removal of an unwanted steady offset voltage from a transducer's output |
front 4 frequency | back 4 the number of occurrences of a repeating event per unit time |
front 5 amplitude | back 5 height of the wave from baseline to crest |
front 6 waveform | back 6 shape and form of a signal |
front 7 wavelength | back 7 length from the crest of one peak to the crest of the next peak |
front 8 skeletal muscle cells | back 8 make up about 40% of the cell mass of the body |
front 9 skeletal muscles so the majority of | back 9 the work for locomotion and support of the animal skeleton |
front 10 each muscle is made up of individual ____ organized in fascicles. | back 10 muscle fibers (muscle cells) |
front 11 to produce mechanical energy in directed movements, | back 11 muscles to the chemical energy stored in ATP |
front 12 skeletal muscle structure- connective tissue sheaths of skeletal muscle: epimysium, perimysium, and endomysium | back 12 |
front 13 disease of muscle are rare and mostly inherited but, | back 13 trauma to muscle is very common |
front 14 upper motor neuron lesions | back 14 loss of muscle function as a consequence of strokes damaging neutons in the brain |
front 15 skeletal muscle is ____ | back 15 consciously controlled and therefore voluntary, can rapidly contract but tires rapidly. |
front 16 excitability | back 16 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 |
