NettetA reflex arc is a neural pathway that controls a reflex.In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord.This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will receive the input while the reflex is … NettetConclusion: Overall, these results indicated that high-intensity interval static training prevents skeletal muscle atrophy and improves the motor function of aged rats through the PGC-1α/FNDC5/UCP1 signaling pathway. Keywords: sarcopenia, static strength training, muscle function, PGC-1α, FNDC5. Corrigendum for this paper has been published.
