How come we elicit stronger reflex when our tendons are relaxed than when we are surrounded by the monkey grip position
Reflexes rely on stretch receptors in the muscle. These stretch receptors fire and grounds muscle contraction when the muscle is stretched. When the doctor taps on your kneecap (for example) the muscle stretches a short time ago enough to fire stale the receptors, which causes the muscle to contract and consequently you see your leg do a slight kick.
If your muscles are already contracted (as contained by a monkey grip), the muscles are already stretched out and the receptors are already stimulated. Any additional stretching cause by the slight hit of a reflex hammer, will not do a reflex contraction of the muscles.
Therefore, in proclaim to get a proper reflex, the muscles must be relaxed.
because when you are tnse yoor jittery system is busy keeping you stuck in your position when you are relaxed your body isnt busy so you can act in response quicker
Reflexes are involuntary responses initiated at spinal cord level. One within monkey grip position consciously controls actions . So reflex are not expressed.
To be more medical cerebral pathway inhibit reflex actions of spinal stratum.
Higher centers in rational cortex inhibit tendon reflex. That`s why in limb paralysed on one side due to stroke tendon reflex lose this inhibition and so are exaggerated.
In monkey grip it`s the reverse.
