What are the tiny gaps between adjacent schwann cells called?
Remember that the Schwann cells are made of myelin sheath which insulate the impulse, but also block the sodium ion/potassium ion channels. Therefore there has to be a point where the action potential 'jumps' to, and these are the gaps between the Schwann cells, they are called the Nodes of Ranvier.
How does insulation of a nerve benefits the functionality of the nervous system?
Insulation of a nerve helps conduct the electric signal through it faster as the signal jumps from node to node along an axon and bypasses the insulation part (Schwann cells). So nerve insulation makes our nervous system more efficient.
What is the name of the cell that forms the myelin sheath around neuron axons?
The cells that are thought to enable myelination to take place are called Glial Cells, which wrap themselves around the axions in a spiral fashion. This creates a sheath, or insulation, around the axion. It is often referred to as 'White Matter'.
How does myelination effect nerve conduction?
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.

How does temperature on a physiological way effect nerve conduction?

What is the difference between free fall and static line parachute jumps?
static line jumps are static, free fall are not :P

No it jumps
Difference between intersegment and intrasegment jump?
Intrasegment jumps are always between statements in the same code segment. Intersegment jumps can transfer control to a statement in a different code segment. Dr Zeeshan
What math is in horseback riding?
Counting strides! Division kind of in between jumps!
Where do lightnings occur?
lightning ocuurs where there is apoint on straight flat land so it is a conductor of electricity I don't know what the first person was saying, but lightning occurs everywhere. In the sky due to a difference in electrical charge. Between the ground and the sky for the same reason. Some static electric jumps you can see lightning. A tesla tower can produce electricity. Between cells in the brain there are "lightning storms" that are jumping between the cells.
