i)-1. Rate of impulse transmission is greater/ faster/ bigger/ higher in the myelinated axon compared to non-myelinated axon, i)-2. Impulse/ action potential will jump from one node to the next node of Ranvier, in myelinated axon// saltatory conduction, ii)-1. Impulse transmission in giant squid is faster than cat, ii)- 2. The bigger the diameter of the axon, the faster the impulse transmission// lesser resistance, Previous depolarized region undergoing repolarization/ Na+ gated are closed/ not reset/cannot respond/ Undergoing refractory periods (that prevents reopening of Na+ gated).
