In each of the following situations, indicate whether theproposed answers are true or false. In each case explain yourreasoning.
In an experiment, a physiologist was able to destroy some butnot all of the motor neurons to a specific skeletal muscle. Givenwhat you know about motor units, what is the result of thisaction?
T/F ?a.??There is no effect because motor neurons are redundant;multiple neurons innervate each muscle fiber as backup.
Explain:
T/F b. The muscle will, in general, contract more weakly becausefewer fibers are capable of contracting.
Explain:
T/F c. The ability of the muscle to contract will not changebecause the electrical potential will spread from stimulated fibersto adjacent fibers.
