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 simplest reflex is the monosynaptic reflex or the two-neuron reflex, an example of which is the tendon jerk reflex or tendon tap reflex, sometimes called the myotatic reflex.This is the reflex that is elicited by tapping the tendon just below the patella.here are other respiratory reflexes as well. For example, the stretch reflex and autogenic inhibition play a major role in control of the intercostal muscles during inspiration. The gamma loop appears to provide an important facilitation of discharges in-motoneurons to the external intercostals in particular.
