Spindle Outputs & Modulation

• • looking at how different intrafusal fibres give different information about the condition of a muscle
  • doing this by looking at adaptive fibres separately to nonadaptive fibres
  • adaptive fibres are just the dynamic bag fibres
  • nonadapative fibres are the static bag fibres and the chain fibres
  • need to consider in detail what happens when a dynamic bag fibre is subjected to stretch - assume muscle is lengthened, stretching the spindle, so stretching the dynamic bag fibres
