What influences the speed of a nerve impulse?
the diameter of an axon
What affects nerve impulse speed?
Nerve impulse speed is affected by the diameter of the nerve fiber (larger fibers conduct faster), the presence of myelin sheath (myelinated fibers conduct faster), and temperature (warmer temperatures enhance conduction speed). Additionally, the refractory period of the neuron and the strength of the stimulus can also influence nerve impulse speed.
Which two characteristics of axons increases the speed of nerve impulse?
diameter and presence of myelination.....
How many speed of impulse in reflex arc?
The speed of impulse in a reflex arc can vary, but it is usually very fast, allowing for quick responses to stimuli. In general, impulses can travel at speeds of up to 100 meters per second along myelinated nerve fibers.
What is the material surrounding the axon that increases the speed of the nerve impulse?
The material surrounding the axon that increases the speed of the nerve impulse is called myelin. Myelin is a fatty substance that acts as an insulating layer, allowing for faster transmission of electrical signals along the axon.
IF an impulse travels 100 ms about how long will it take the impulse to travel 10 meters?
The speed of an impulse traveling through a medium is determined by the medium's properties. If the speed of the impulse is known, we can calculate the time it takes to travel a certain distance using the formula time = distance / speed. However, without knowing the speed of the impulse, we cannot accurately determine the time it will take to travel 10 meters.

Which of the following types of nerve fiber possesses the fastest speed of impulse propagation?
Myelinated A fibers have the fastest speed of impulse propagation among nerve fibers.
What is speed of impulse propagation?
The speed of impulse propagation in neurons is typically around 1-100 meters per second, but can vary based on factors such as the type of neuron and the presence of myelin sheath. In cardiac tissue, the speed of impulse propagation is slower, around 0.5 to 1 meter per second.
What affects nerve impulse speed?
Nerve impulse speed is affected by the diameter of the nerve fiber (larger fibers conduct faster), the presence of myelin sheath (myelinated fibers conduct faster), and temperature (warmer temperatures enhance conduction speed). Additionally, the refractory period of the neuron and the strength of the stimulus can also influence nerve impulse speed.
Do you experience an impulse when you catch a ball of the same speed?
Yes, when you catch a ball moving at the same speed, there is an impulse involved. Impulse is the change in momentum that occurs when the ball makes contact with your hand. As you catch the ball, your hand exerts a force to stop its motion, resulting in a change in momentum and thus an impulse experienced by both the ball and your hand.
What increases the speed of impulse transmission?
Myelin Sheath Myelin Sheath
Increases the speed of impulse transmission?
axon terminal Its the Myelin Sheath.
Speed of a soccer ball?
Zero - until it is imparted an impulse by a player.
How fast is impulse power on StarTrek?
== == From what I remember, impulse speed was used to dock and leave a space station; so it would make sense that this form of movement has a low velocity (try parking a car at 80mph). Warp speed is supposedly faster than the speed of light, I think... So warp speed is faster than impulse speed. Warp speed, as above, is faster than light, whereas impulse speed is used to move around within a sector of space. Warp speed is much, much faster. According to the Star Trek Encyclopedia, which uses the Okuda warp scale, impulse speed is 1/4 lightspeed, or 270 million km/h. Warp 1 is lightspeed, or 1078 million km/h. Any warp factor is considerably faster than impulse (or "sublight") engines.

The speed of impulse conduction along an axon may be increased by?
By myelin sheath.
