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 the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
How does myelination affect nerve conduction velocity?
Myelination will speed the nerve conduction velocity considerably. Myelin is found in Schwann cells which encircle a given axon. It acts mainly as an insulator so that depolarization in one cell does not set off depolarizations in adjoining cells. When a neural membrane is depolarized, local currents are set up between positive and negative ions causing membrane conduction. In myelinated fibers, the local currents go from one internode (or node of Ranvier) in between two Schwann cells to the next internode. Thus we have "salutatory conduction" where a neural impulse actually jumps from one internode to the next without being conducted down the entire cell membrane.

What is the relationship between displacement and velocity?
velocity = displacement / time taken
What is relationship between velocity and acceleration?
sorry '=
What is the relationship between accerleration and velocity?
Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.
What is the relationship between velocity and acceleratioñ?
Acceleration is the rate at which velocity changes and the direction of the change.
What is the relationship between the mass and velocity of an object in uniform acceleration?
Momentum=mass*velocity
What is the relationship between starting length and initial velocity of shortening?
The lighter the weight, the greater the initial velocity of shortening; inverse relationship.
The relationship between velocity and acceleration?
Regarding their magnitudes . . . Acceleration is the time rate of change of velocity. Regarding their directions . . . There's not necessarily any relationship between the two.
