Stopping Exercise: Role of Pulmonary C Fibers and Inhibition Of Motoneurons.
نویسندگان
چکیده
In animals, the J reflex evoked by pulmonary C fibers provides potent inhibition of limb muscles and would act to limit exercise. However, recent work shows that although activation of these fibers causes severe respiratory discomfort, it does not impair the output of limb motoneurons to voluntary, reflex, or locomotor drives in awake humans.

Introduction: TNF-α/NF-kB signaling pathway plays an important role in promoting the inflammatory process and growth of breast cancer. Accordingly, the aim of the present study was to investigate the synergistic combination effect of endurance exercise with curcumin on breast cancer progression through TNF-α/NF-kB signaling axes in female BALB/c mice with breast cancer. Methods: The design of ...
متن کاملThe effect of hypothyroidism on the trigeminal calcitonin gene-related peptide containing motoneurons: an immunohisto-chemical study in late neonatal life
CGRP, which coexists with acetylcholine in trigeminal motoneurons, could be one of the regulatory anterograde factors responsible for the enhanced expression of AChR subunits in neuromuscular junction. It has been also shown that low level of thyroid hormone plasma concentration has influence on the transitional development of muscle fibers and related motoneurons through a sever reduction in A...

متن کاملAlteration in postnatal development of masseter innervation in hypothyroid rats
The thyroid hormones have profound effects on the development of neuromuscular system. These hormones exert their influence on both muscle fibers and related motoneurons during development. Masseter is one of the most important muscles for mastication in mammals. Thyroid hormone deficiency 3 weeks after birth, the period in which an alteration from sucking to biting occurs, could influence the ...
