| Abstrakt: | The myotatic reflex is monosynaptic, induced by the sudden passive muscle belly fiber stretch, and produces a muscle contraction in the agonist muscle or muscle group with simultaneous antagonist muscle (or muscle group) relaxation.[1] As with all reflexes, it is involuntary, reproducible, and likely is positively selected evolutionarily, specifically to prevent the forceful stretching or pulling of a muscle beyond its normal passive range. This reflex also has utility in helping maintain upright posture by detecting postural muscle group stretch and reflexively correcting accordingly in the common cases of leaning or postural instability, which conserves expended energy.[2] Additionally called the deep tendon, stretch, and jerk reflex, the myotatic reflex is a fundamental and essential part of the neurological examination since the work by Joseph Babinski, Wilheim Erb, and William Gowers in the late 1800s.[3][4] (Copyright © 2021, StatPearls Publishing LLC.) |
