Chapter Summary: "The nervous system carries messages to the brain and from the brain back through your body to the proper organs and muscles for action." Nerves need to be used often to continue to function properly. Singing involves both hemispheres of the brain since speech comes from the left while music and emotions come from the right. Because of our sympathetic nervous system, our voice reacts to other physical sensations, such as an injury or tension. Our empathetic nervous system affects how our voice reacts to outward stimuli.
Key Concept: Nerves must be used frequently to stay healthy. After a lot of practice, conditional reflex can develop. Our singing voice reacts to both hemispheres of the brain, our past and outward stimuli.
Key Terms: voluntary and involuntary nervous systems, medulla oblongata, hypothalamus, neuron, axons, dendries, afferent and efferent nerve fibers, conditioned reflex, point of saturation, synapse, kinesthetic senses, biofeedback, endocrine system, hormones, laryngeal nerve, glossopharyngeal nerve, facial nerve, sympathetic nervous system, empathetic nervous system, slow-twitch motor units, fast-twitch motor units
Making Connections: I need to work on remembering how I feel physically when I sing well and try to memorize those sensations. I need to practice with the goal of conditional reflex.
