What influences the speed of a nerve impulse?
the diameter of an axon
Which two characteristics of axons increases the speed of nerve impulse?
diameter and presence of myelination.....
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
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.
Do impulses move faster or slower along the nerve at lower temperatures?
Impulses move slower at lower temperatures because temperature affects the speed of nerve conduction by altering the rate of chemical reactions involved in transmitting the impulse. Cold temperatures slow down these chemical reactions, causing nerve impulses to travel more slowly.

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 affects the speed of nerve transmission and how is it measured?
The speed of nerve transmission can be affected by factors such as the myelination of the nerve fiber, temperature, and the diameter of the nerve fiber. It is measured using techniques such as nerve conduction studies, where electrodes are placed on the skin to measure the speed of electrical impulses along a nerve.
How does a nerve impulse follow all or nothing principle?
How does a nerve impulse follow the all-or-nothing principle???
Do impulses move faster or slower along the nerve at lower temperatures?
Impulses move slower at lower temperatures because temperature affects the speed of nerve conduction by altering the rate of chemical reactions involved in transmitting the impulse. Cold temperatures slow down these chemical reactions, causing nerve impulses to travel more slowly.
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
