IN MY HUMBLE UNDERSTANDING:
1.BOTH ALPHA AND GAMMA MOTONEURONS ARE LOWER MN THAT PARTICIPATES IN REFLEX
2 ALPHA MN INERVATE A GROUP OF MUSCLE FIBERS -MOTOR UNIT-BASIC UNIT FOR VOLUNTARY,POSTURAL AND REFLEX ACTIITY
3GAMAMN ACTS A SENSORY RECEPTOR IN SKELETAL MUSCLE STRECH
4THE STRECH REFLEX IS A BASIC REFLEX AND MECHANISM FOR REGULATE TONE
STRECH OF THE SPINDLES -----(ARROW)------ACTIVATES GAMA -Ia AFFERENTS MONOSYPNATICALLY----------THEN STIMULATES ALPHA-----------CAUSE CONTRACCION.---------.AND INHIBIT ANTAGONIST MUSCLE
INVERSE MUSCLE STRETCH REFLEX
USES GOLGI TENDON ORGANS
STRECH O THE SPINDLES------------ACTIVATES GTO Ib --------POLYSYPNAPTICALLY FACILITATE ANTAGONISTA AND INHIBT AGONIST......
5 UPPER MOTONEURONS--------INERVATE GAMA-------ALPHA--------TONE
WELL I WAIT HELP YOU FOR A LEAST A LITTLE.......
