Nerve supply and muscle fiber stimulation
WebDec 4, 2024 · The generation of action potentials in intramuscular motor and sensory axons in response to an imposed external current source can evoke muscle contractions and elicit widespread responses throughout the nervous system that impact sensorimotor function. The benefits experienced by individuals exposed to several weeks of treatment with … WebMay 12, 2024 · Figure 10.4. 1: Types of Muscle Contractions. During isotonic contractions, muscle length changes to move a load. During isometric contractions, muscle length does not change because the load exceeds the tension the muscle can generate. All of these muscle activities are under the exquisite control of the nervous system.
