The H-reflex (or Hoffmann's reflex) is a reflectory reaction of muscles after electrical stimulation of sensory fibers (Ia afferents stemming from muscle spindles) in their innervating nerves (for example, those located behind the knee).fter about 5 days in zero gravity, for instance in orbit around Earth, the h-reflex diminishes significantly. It is generally assumed that this is due to a marked reduction in the excitability of the spinal cord in zero gravity.
The Hypoglossal Nerve is the twelfth of the Twelve Cranial Nerves. The fibers consist of Efferent Motoric and Afferent Sensory fibers. The word Afferent means toward the centre, as in from a peripheral area of a limb to the central nervous system.he pathway for the Efferent motoric fibers of the Hypoglossal nerve is the following (from the initiation in the brain to the termination in the periphery): 1  The Nucleus of the Hypoglossal Nerve is situated in the brainstem at the level of the Hypoglossal Trigone.
