Final answer:
The motor component of skeletal muscle reflexes is mediated by lower motoneurons.
Step-by-step explanation:
The motor component of skeletal muscle reflexes is mediated by lower motoneurons. These lower motoneurons have their cell bodies in the ventral horn of the spinal cord and project to the skeletal muscles in the periphery.
The upper motoneurons, on the other hand, have their cell bodies in the primary motor cortex of the frontal lobe and synapse on the lower motoneurons.
