CNS response to the periphery to produce contraction of the skeletal muscles is the result of
a. efferent fibers. c. myelin sheath.
b. afferent fibers. d. neurotransmitters.
A
Efferent fibers (motor fibers) transmit the central nervous system (CNS) response to the periphery to produce a motor response such as contraction of skeletal muscles, contraction of the smooth muscles of organs, or secretion by endocrine glands. This sensory information is transmitted to the CNS by afferent fibers (sensory fibers). Fibers enclosed in the sheath are called myelinated fibers. Neurotransmitters help with nerve transmission from one neuron to the next.
