How can you get faster reflexes?
These are some good reflex exercises you can practice:
1. Woods Running - Run through any wooded area, dodging trees and navigating uneven terrain. The faster you go, the better practice it is.
2. Wall Ball - bounce a ball against a wall. Standing closer to the wall and throwing harder will make it more difficult. The best way is with an oddly shaped ball so the bounce is not predictable.
3. Slap a Friend - This one requires a partner. The partner holds his or her hands out and your put your hands on top of theirs and they try to slap the tops of your hands before you can pull them away. There are many variations of this game that can make it more difficult if you're creative enough.
Answer1st know what your strengths are: strategy, skill, speed, strength, etc..You can't have it all, know what your strengths are 1st and build upon that.
You can strengthen your lack in speed by training hard with a really good trainer!
Answerbe more alertOr, you can repeatedly use a variety of stimuli to enhance your prowess of you're reflexes
AnswerReflexes depend on three main factors: vision (sight), coordination (neuromuscular) and reaction time (neurological)The first can be educated and trained with specific exercises mainly training sudden change of depth or focus, lateral vision and "scanning". You can also add some Vitamin A to your nutrition.
The second can also be trained with specific exercises particularly "centering", balance and sudden response movements. A good nutrition will also keep your system sharp
The third can be trained with concentration exercises and the alternation of concentration and relaxation as well as exercising all your cognitive senses daily.
Once you have set a good training plan on all three factors, play games as i.e. throwing a tennis ball against a wall at short distance and go decreasing the distance daily.
How is Stroke a nervous disorder?
It isn't. A stroke is a cardiovascular event that CAN (might) affect the nervous system, specifically, the brain. If so, then it CAN (might) affect the muscular system through where the damage occurred in the brain. Stroke CAN (might) affect speech and memory as well. But stroke is still a cardiovascular event.
Is insulin cross blood brain barrier?
Insulin does crosses the blood brain barrier. Insulin crosses the blood brain barrier through the process of receptor-mediated transcytosis.
What is a disorder of the nervous system that involves glia rather then neurons?
Most disorders of nervous system cell involve glia rather than neurons. Multiple sclerosis (MS) one ot the mylein disorders, is a good example of this principle.
How not to get nervous while playing the nervous game?
It depends on the version but the watered down version or really any of them just dont think about it and you wont get nervous
True or false Shivering from being nervous or cold can cause somatic tremor?
false, the causes of somatic tremor is parkinson's disease, and also by cold or body tremors
Which part of the nervous system is being activated during yoga?
The Frontal Cortex, usually involved in focusing attention and concentration, is more active during meditation
The parietal lobe. This area of the brain is responsible for giving us a sense of our orientation in space and time
Parasympathetic because it is the exact opposite of Sympathetic Fight or Flight
What are the two groups of nerves into which the peripheral nervous system is divided?
Involuntary and voluntary actions
somatic nervous system and autonomic nervous system
Hypothalamus
Spinal nerves carry what kind of information?
The spinal cord handles electrical signals sent between the brain and the rest of the body.
What can happen if a person inhale purewhip?
purewhip is 40% oxygen it is one of the fake N2O chargers dont inhale it wont hardly do anything...........
Why when someone tickles your ribs it tickles?
It is a sensation that makes your ribs ticklish and it makes you laugh
The hair cells of the utricle and saccule are clustered in?
The hair cells of the utricle and saccule are clustered in structures called maculae. These maculae are specialized sensory regions within the inner ear that detect changes in head position and linear acceleration. The hair cells within the maculae are essential for signaling information related to balance and spatial orientation to the brain.
What would happen if a nerve fiber was stimulated from both ends simultaneously?
The neural activity progresses as if it were a wave (the effect moves but the nerve, of course does not). As the wave progresses it depolarizes the nerve surface, opens Na+ channels and activates the nerve surface as it goes forward. One effect of the firing however is that the Na+ channels inactivate and enter a refractory period in which they will not reopen. This essential drives the propagation wave in one direction only.
If the nerve were to be simultaneously stimulated at both ends the two waves would meet and then activity would cease. Neither wave would be able to overcome the refractory membrane that the other wave had passed over.
What is the inferior boundary of the spinal cord?
In adults, the spinal cord terminates at approximately the level of L1. The nerve roots then descend through a fluid sac containing cerebrospinal fluid and are referred to as the cauda equina ("tail of a horse").
