What is arch reflex

What do you mean by the arch reflex?

E

Expert

Verified

In some of the situations, the movement of skeletal striated muscles does not depend on the commands of superior motor neurons, that is, it is not triggered by the volition. Involuntary movements of those muscles generally take place when the sensory fibers which make direct or indirect connection with the inferior motor neurons are unexpectedly stimulated in situations which propose danger to the body. This occurs, such as, in patellar reflex, or knee jerk reflex, when a rapid percussion over the knee patella  triggers an involuntary contraction of the quadriceps. Other example of arch reflex takes place whenever someone steps on the sharp object: one leg retracts and the other, by the arch reflex, distends to manage the equilibrium of the body.
