A Node of Ranvier is the space between two myelinated segments on an axon, while an internode is the space between two Nodes of Ranvier (alternativenly, the myelinated segment).
The spaces along the axon and between the myelin sheath are known as the nodes of Ranvier. They are responsible for speeding up the signals that are transmitted along the axon of the nerve. While the myelin sheath consists of many layers that protect the axon, the nodes of Ranvier are uncovered, giving them the ability to produce an electrical charge.

wherever the Schwann cells wrap around the axon, the sodium and potassium ions cannot cross the membrane; the Schwann cells wrap too tightly around the axonal membrane for there to be any extracellular space underneath them. Therefore, the only place that an action potential can occur is at the node of Ranvier-- the space between the Schwann cells. Because of this, the action potential seems to jump from node to node along the axon. "Jumping" is what the word "saltatory" means.
Node is the point on the vibrating string with zero amplitude and antinode is the point where amplitude is the maximum. The distance between successive node will be half of the wavelength.

THE POINT FROM WHERE THE LEAF ARISES IS KNOWN AS NODE. THE DISTANCE between 2 consequitive nodes is known as internode.. from a node leaf arises but from the internode no leaf arises internode is a part of stem as node is not but is a part of leaf
Node of Ranvier
The cleft between the internodes of the myelin sheath is called the node of Ranvier. This region is important for the propagation of action potentials along the axon.
An internode is a portion of plant stem between nodes. An internodal segment is a portion of nerve fibre.
The spaces along the axon and between the myelin sheath are known as the nodes of Ranvier. They are responsible for speeding up the signals that are transmitted along the axon of the nerve. While the myelin sheath consists of many layers that protect the axon, the nodes of Ranvier are uncovered, giving them the ability to produce an electrical charge.
The node is the part of the stem of the plant from which leaves, branches, and aerial roots emerge. There are many nodes on a plant stem. The distance between each node is called the inter node.
The node of Ranvier is a gap in the myelin sheath of a nerve cell where action potentials are generated and help speed up the transmission of nerve impulses along the axon.
The node of Ranvier plays a crucial role in the conduction of nerve impulses by allowing for faster and more efficient transmission of electrical signals along the nerve fiber. This is because the gaps at the node of Ranvier help to regenerate the electrical signal, allowing it to travel more quickly down the nerve fiber.
The naked axon between Schwann cells is called the Node of Ranvier. It is a short unmyelinated segment of the axon where action potentials are generated during saltatory conduction. Nodes of Ranvier are essential for increasing the speed of nerve impulse transmission along myelinated neurons.

The area between two successive nodes is referred to as an internode. The node is the area where a leaf connects to the stem.
The Node of Ranvier is a gap in the myelin sheath of a neuron that facilitates rapid signal transmission. It allows for the regeneration of action potentials through a process called saltatory conduction, where the electrical impulse jumps from one node to the next. This increases the speed of nerve signal propagation, making communication between neurons more efficient. Overall, Nodes of Ranvier play a crucial role in maintaining the rapid transmission of electrical signals along myelinated axons.
