Factors that effect reaction time?
The sensitivity of the receptors, velocity of nerve conduction, and the number of neurons and synapses involved to name a few.
What would happen if the inertia of the earth was increased without he sun's gravity increasing?
Inertia is measured by an object's mass. The Earth would still go around in the same orbit, because the orbit does not depend on the mass of a planet. "Inertia" is sometimes used to mean "momentum". That's mass times velocity. If the Earth's velocity increased then it would move further from the Sun. <<>> The point is that "inertia" is a nonscienific word that is used to describe different things by different people and it's best to use "mass" or "momentum" depending on what is meant.
What is the duration of Velocity Trap?
The duration of Velocity Trap is 1.48 hours.
What is the duration of The Velocity of Gary?
The duration of The Velocity of Gary is 1.68 hours.
What is the acceleration of an object?
When a net force acts on that object, there is a change in velocity, and thus acceleration.
Who invented the nerve conduction velocity test?

What are the factors which affect the nerve conduction velocity?
The factors affecting nerve conduction velocity are as follows:(i) Axon diameter:An axon with a larger diameter conducts faster. In an unmyelinated fiber, the speed of propagation is directly proportional to the square root of the fiber diameter (D), i.e.,Conduction velocity a D(ii) Myelination and saltatory conduction:Myelination speeds up conduction. Thus, the action potential travels electrotonically along the long myelinated segments, and fresh action potentials are generated only at the nodes. This is called saltatory conduction. In a myelinated neuron, the conduction velocity is directly proportional to the fiber diameter (D).(iii) Temperature:A decrease in temperature slows down conduction velocity, (iv) Resting membrane potential. Effect of RMP changes on conduction velocity is quite variable. Usually, any change in the RMP in either direction (hyper polarization or depolarization) slows down the conduction velocity.
What is the relationship between the diameter of axon and conduction velocity?
There is a positive relationship between the diameter of an axon and its conduction velocity. Larger axon diameters result in faster conduction velocities due to decreased resistance to ion flow. This relationship is described by the principle of "the larger the diameter, the faster the conduction."
What is the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
What is the relationship between size of nerve and conduction velocity?
For unmyelinated nerves there is a relationship between axon diameter and conduction velocity. Larger diameter nerves conduct faster. For myelinated nerves the a larger diameter nerve will conduct faster between the nodes of ranvier where the action potential is propagated. Conduction is said to be saltatoryas it jumps from node to node.
What is increased to slow down conduction?
Increased resistance can slow down conduction. This can occur in nerve fibers with a smaller diameter or in demyelinated nerves, where the insulation around the nerve fibers is reduced, leading to decreased conduction velocity.
If you have increased the momentum of a moving object without increasing its inertia then you have?
Increased its velocity. By not changing its mass (inertia) and increasing its momentum, the only variable left to change is velocity in the equation momentum = mass x velocity.
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
What features of nerves improve impulse conduction velocity?
myelin sheaths
What is salutatory conduction?
Saltatory conduction is a process where nerve impulses jump from one Node of Ranvier to another along a myelinated axon, leading to faster transmission of the signal compared to continuous conduction in unmyelinated axons. This increase in speed is due to the insulation provided by the myelin sheath, which forces the signal to "leap" between gaps in the insulation.
Does the presence of the nodes of ranvier speed up velocity of conduction along the axon?
True
The velocity of nerve impulse conduction is greatest in?
Heavily myelinated, large diameter fibers
