What is the function of Golgi tendon organs?
A. They detect the angle of joints, and thus provide proprioceptive inputs about the position of the limbs in space.
B. They detect stretch within tendons and inhibit the activation of alpha motor neurons to extrafusal muscle fibers in antagonistic muscles.
C. They detect stretch within tendons and inhibit the activation of alpha motor neurons to extrafusal muscle fibers in the muscle attached to those tendons.
D. They detect painful stimuli within tendons and inhibit gamma motor neurons to intrafusal muscle fibers in muscles attached to those tendons.
E. They stimulate the ends of intrafusal muscle fibers, ensuring that sensory information about muscle length is provided, even when a muscle shortens rapidly.
