Another useful reflex is the flexion withdrawal that occurs when the bare foot encounters a sharp object. Involuntary muscles, also known as “white muscles” or “smooth muscles”, are muscles in the human body whose contraction is controlled by the autonomic nervous system. TD may be mild and reversible in many cases. Blinking. Thus, even the simplest of reflexes involves a coordination of activity across motor neurons that control agonist and antagonist muscles.

This slight muscle stretch is “sensed” by receptors in the muscle called muscle spindles. Our summaries and analyses are written by experts, and your questions are answered by real teachers. For example, the sensitivity of the muscle spindle organs is monitored by the brain through a separate set of gamma motor neurons that control the specialized muscle fibers and allow the brain to fine-tune the system for different movement tasks. He has full control over it. These movements are controlled by the nervous system which has several divisions such as the ANS (autonomic nervous system), CNS (central nervous system) and PNS (peripheral nervous system).
