Step by step
Solved in 2 steps
- How does the nervous system speciically control the muscular system?The disease poliomyelitis (po′le-o-mi′˘e-li′tis) destroys motor neurons, causingloss of muscle function and even flaccid paralysis. Some patients recoverbecause axon branches form from the remaining motor neurons. Thesebranches innervate the paralyzed muscle fibers to produce motor unitswith many more muscle fibers than usual. How does this reinnervation ofmuscle fibers affect the degree of muscle control in a person who hasrecovered from poliomyelitis?What are the positions ofactin and myosin molecules inthe sarcomere before andduring the musclecontraction?
- If implanted electrodes were used to stimulate action potentials in gamma motor neurons to flexors of the left arm, which would be the most likely result?a. inhibition of the flexors of the left armb. a decrease in action potentials from muscle-spindle receptors in the left armc. a decrease in action potentials from Golgi tendon organs in the left armd. an increase in action potentials along alpha motor neurons to flexors inthe left arme. contraction of flexor muscles in the right armTo increase the strength ofthe muscle work is the musclecontraction intenselyincreased?The location of a muscle’s insertion and origin candetermine ________.a. actionb. the force of contractionc. muscle named. the load a muscle can carry
- The crista ampullaris is sensitive to :-a- sound vibrationsb- force of gravityc- linear accelerationd- angular accelerationExplain why muscle tone is first decreased and then increased when descending motor tracts aredamaged. How is muscle tone maintained?Explain why the ratio of motor neurons to muscle fibers isgreater in muscles that control eye movement than in posturalmuscles of the leg.
- Stretch of an innervated muscle evokes :-a- contraction of its spindlesb- contraction of its extrafusal fibersc- contraction of antagonistic musclesd- relaxation of synergistic musclesWhat is theneurotransmitter of theneuromuscular junction?
