  • Repeated nerve injury can invoke death of the nerve cell body and failure to regenerate. (cdc.gov)
  • For example, it tells your muscles how to move so you can walk, talk, and do the things you want your body to do. (merckmanuals.com)
  • Like the other muscles in your body, your facial muscles contract (tighten) and relax in response to specific stimuli. (rifkindental.com)
  • We show that a selective activation and expansion of Itga7+ glial cells occur in response to muscle nerve lesion. (jci.org)
  • Expression lines, also known as dynamic wrinkles, occur due to repetitive muscle movements, such as those involved in facial expressions. (usapeptides.info)
  • For your facial muscles, most contractions occur when we're making facial expressions, like smiling or frowning. (rifkindental.com)
  • Once the signal reaches the axon terminal bundle, it may be transmitted to a neighboring nerve cell with the action of a chemical neurotransmitter . (gsu.edu)
  • A nerve cell is like a receiver, transmitter and transmission line with the task of passing a signal along from its dendrites to the axon terminal bundle. (gsu.edu)
  • When the nerve signal from the somatic nerve system reaches the muscle cell, voltage-dependent calcium gates open to allow calcium to enter the axon terminal. (gsu.edu)
  • Receptors often include nonneural elements which incorporate and interact with the axon terminal in initiating generator potentials. (cdc.gov)
  • An exam- ple of a slowly adapting position detector is a Type I Iggo corpuscle, featured by a myelinated axon ter- minating at the base of a small dome-like elevation in the skin (Merkel cells). (cdc.gov)
  • Displacement of the dome by as little as 5 ,um can result in a supra-threshold generator potential within the Merkel cell-axon ter- minal complex. (cdc.gov)
  • Interestingly, we observed that the activation of muscle glial cells by acute nerve injury was reversible upon NMJ repair. (jci.org)
  • Mast cells secrete histamine that inhibits vasoconstriction via H2 receptors on smooth muscle cells. (cdc.gov)
  • This calcium moves the acetylcholine-containing miceles to fuse with the presynaptic membrane and release their acetylcholine into the synapse, where it is bound by acetylcholine receptors on the postsynaptic surface. (gsu.edu)
