Gaps between segments of oligodendrocytes or between individual schwann cells are called?
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.
What is the main difference between manet and vanet?
In manet node Mobility is slow. In Manet no Fixed Infrastructure . In Vanet Node Mobility Very high. In Vanet have Fixed Infrastructure . Ex . BTS
Is saltatory conduction faster than conduction on an unmyelinated fiber?
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.
What is node and antinode?
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.
What is Cardiopulmonary node?
cardiopulmonary node
What is the different between a node and internode?
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
What are the gaps between the myelin sheath along an axon?
Node of Ranvier
What is the name for the cleft between the internodes of the myelin sheath?
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.
What is inter-node?
An internode is a portion of plant stem between nodes. An internodal segment is a portion of nerve fibre.

What are nodes and internodes?
In plants, nodes are the points where leaves, buds, and branches are attached to the stem. Internodes are the segments of stem between two nodes. Nodes play a crucial role in the growth and development of plants by producing new leaves and branches.
What is the function of the node of Ranvier in the nervous system?
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.
What is the significance of the node of Ranvier in the conduction of nerve impulses?
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.
What is the naked axon between the schwann cell?
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.
What are d common parts of dicot stem?
main stem=secondary stem==node==internode=
What is the space between nodes called?
The space between nodes in a network is typically referred to as an edge or a link. This edge represents the connection or relationship between the nodes in the network.
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.
