Solution
The "reverse myotatic reflex" is best described as: the Golgi tendon organ afferent is activated by muscle tension leading to a polysynaptic reflex in the spinal cord which inhibits the motor neuron to the same muscle.
Here's the step-by-step explanation:
-
The Golgi tendon organ (GTO) is a proprioceptive sensory receptor organ that senses changes in muscle tension. It is integrated into the muscle and tendon fibers.
-
When there is an increase in muscle tension, the GTO is activated. This means it sends a signal to the spinal cord.
-
This signal triggers a polysynaptic reflex in the spinal cord. A polysynaptic reflex involves multiple synapses, meaning the signal is transmitted across more than one nerve cell or neuron.
-
This reflex inhibits the motor neuron to the same muscle. In other words, it reduces the activity of the motor neuron, which in turn reduces the tension in the muscle.
This reflex is a protective mechanism to prevent the muscle from exerting too much force and potentially causing damage.
