That substance is called the myelin cell or myelin sheath.
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.
Unmyelinated nerve fibers conduct impulses more slowly than myelinated nerve fibers. Myelinated nerve fibers have a fatty substance called myelin sheath that allows for faster transmission of impulses compared to unmyelinated fibers without this sheath.
The heart's electrical conduction system interacts with cardiac muscle tissue to regulate the heartbeat. Specialized cells in the heart generate electrical impulses that travel through the heart muscle, causing it to contract and pump blood effectively.
sensory neurons
no you give an answer im the one that asked the question
Nerve impulses do not travel at 170 mph; instead, they can vary significantly in speed depending on the type of nerve fiber. In myelinated fibers, impulses can travel at speeds up to about 120 meters per second (approximately 268 mph), while unmyelinated fibers are much slower. Thus, while some nerve impulses can approach high speeds, they do not typically reach 170 mph.
Yes, neural impulses travel faster than hormonal messages. Neural impulses are electrical signals that travel along nerve cells at speeds of up to 120 meters per second, while hormonal messages are transmitted through the bloodstream at slower speeds, ranging from a few centimeters to a few meters per second.
Cardiac muscle tissue has gap junctions to allow impulses to travel quickly though the tissue so the two atria can contract as one and the two ventricles can contract as one.
The dendrites of one neuron send electrical impulses called synapses to the axons of other neurons to transport information.
The speed at which your nerve impulses travels is dependent on the type of fiber. On fibers that allow the nerve to travel faster can reach speeds of over 200 miles per hour.
yes, in woman nerve impulses travel to the brain faster than men

Yes. Light has a speed, electric impulses from the retina to the brain have speeds and the neurons in the brain have speeds.
Nerve impulses travel through nerve fibers, and the speed of which they travel depends on the type of nerve fiber. They travel usually around 86 miles per hour.
They do not travel - their position is fixed throughout the body. Nerve impulses travel.
It is the "skipping" pattern that impulses follow to travel down nerve axons.
Reaction time is the time it takes for a stimulus to be perceived and for a response to be initiated. Nerve impulses travel at different speeds depending on the type of nerve fiber, but generally, it takes a fraction of a second for a nerve impulse to travel from a sensory receptor to the brain for processing and then back to the muscles for a response. Factors such as practice, age, and physical condition can affect reaction time.
