Does sensory neurons for touch also carries pain impulses?
yes touch receptors can also feel pain you have to touch or be hurt by something or someone for that impulse to relay back to the brain that, yes, that did hurt or, yes, I am in pain
Why do your fingers cause a spark when you touch everything?
Your body can hold electric charge. When you touch something that can conduct electricity (or is at a different potential), the charge in you will travel. It sparks when you are close enough for the charge to travel through the remaining air gap.
Why is it helpful to have impulses to move only in one direction in a neuron?
Your neurons are adapted in such a way that impulses move only in one direction.
Using the gate control theory of pain modulation to explain why applying touch or other nonpainful stimulus to the ache site of the body can reduce pain feeling?
the gate control theory states that peripheral nerve fibers carrying pain to the spinal cord can have their input modified at the spinal cord level before transmission to the brain. synapses found in the dorsal horns acts as gates that close to keep impulses from reaching brain or open to allow impulse to pass. small diameter fibers are the ones carrying pain impulses while large diameter fibers carry nonpainful impulses. applying touch to area of pain decreases pain because touch stimulates the large fiber diameters which in turn closes the 'gate'
The two main ways in which neurons are able to react to stimuli are?
The two main ways in which neurons are able to react to stimuli are conduction impulses and communicating with each other. These stimuli can be touch, sound, light, taste, and smell.
How fast do nerves impulses travel?
Nerve impulses travel through nerve fibers via a action potential and the speed at which the impulse travels depends on the type of nerve fibre. This can range from 100m/s in the case of touch to 20-30 m/s when you're thinking.
What phenomenon explains why a light touch feels different than a touch applied with more pressure?
frequency of impulses
What happens when you touch calcium metal?
Sensory nerves in your finger trigger minute electrical impulses which travel to your brain. Your brain then interprets those impulses as one thing or another and you say, "Hmm, that's what calcium metal feels like."
What tract conveys nerve impulses for crude touch and pressure?
spinothalamic, it is a somatosensory pathway
Sensory impulses transmitted over the facial glossopharyngeal and vagus nerves are involved in the sensation of?
The taste and touch sensation
Does sensory neurons for touch also carries pain impulses?
yes touch receptors can also feel pain you have to touch or be hurt by something or someone for that impulse to relay back to the brain that, yes, that did hurt or, yes, I am in pain
What does a keyboard sense?
A computer keyboard senses pressure on the keys. A touch screen keyboard can sense electrical impulses from the user's fingers.
Is Hollywood out of touch with the US?
No,H.U. is going to stay in touch of the U.S. and travel around the world.
What does nervous system do?
Sends reactions to the brain that have to do with feel and touch. The spinal cord is very important. Chemichal messengers send the impulses to the brain

How many yards does the ball have to travel on an onside kick before the receiving team can recover it?
The ball must travel at least ten yards and it must touch the ground . The order of these occurances does not matter. These restrictions are not in effect if the receivers touch the ball first. If the ball is touched by the receivers first either team may recover the ball but only the receivers may advance the kick.
What is 'modality of sensation'?
Each type of the principal type of sensation that we experience pain , touch, sight ,sound and so forth is called modalities of sensation. We experience these different modalities of sensation, while nerve fibers transmit only impulses. How is it that different nerve fibers transmit different modalities of sensation? 1. Each nerve tract terminates at a specific point in the CNS, and the type of sensation is determined by the point in the nervous system to which the fiber leads. So touch stimulus is carried by nerve impulses in the touch area of the brain. Similarly fibers from the eyes (retina) terminates in the "visual Corteses" of the brain, touch stimuli carried by nerve impulses in the "touch" area of the brain. 2.Moreover, each receptor organ is specialized to receive a particular type of stimuli and this is carried to the particular area of the bran.
