neuronas gamma motoras
Scope note: Neuronas motoras que activan las regiones contráctiles de las FIBRAS MUSCULARES ESQUELÉTICAS intrafusales y de esta forma ajustan la sensibilidad al estiramiento de los HUSOS MUSCULARES. Las neuronas motoras gamma pueden ser "estáticas" o "dinámicas", de acuerdo con el tipo de respuesta (o qué tipo de fibras) que regulan. Las neuronas motoras alfa y gamma a menudo se activan juntas (coactivación alfa gamma), lo cual permite a los husos contribuir al control de la trayectoria del movimiento a pesar de los cambios en la longitud del músculo.

Scope note: Motor neurons which activate the contractile regions of intrafusal SKELETAL MUSCLE FIBERS, thus adjusting the sensitivity of the MUSCLE SPINDLES to stretch. Gamma motor neurons may be "static" or "dynamic" according to which aspect of responsiveness (or which fiber types) they regulate. The alpha and gamma motor neurons are often activated together (alpha gamma coactivation) which allows the spindles to contribute to the control of movement trajectories despite changes in muscle length.
