Brief view at Structure Function Mechanism Muscle spindle Brief view at Structure Function Mechanism

Structure Motorneurones … alpha & gamma Muscle Fibers … Extrafusal & Intrafusal Intrafusal … Nuclear bag & Nuclear chain Sensory … II group & Ia group Motor .. Static & Dynamic

Function Main function of Muscle spindle : Correction for changes in muscle length when extrafusal muscle fiber either shortens or lengths .
