The gap between Schwann cells in the peripheral nervous system is called a node of Ranvier. These nodes play a critical role in signaling transmission along the nerve fibers by allowing for the rapid diffusion of ions.
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.
They are called as vesicles. They are constantly created. They contents the neurotransmitter. Neurotransmitter is required for transmission of the nerve impulse.
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 transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.

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.
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.
Nodes of Ranvier
Its where there are a lot of sodium channels. Once the trigger zone is 'triggered' to threshold (from -70mV to -55mv), then an action potential occurs. trigger zone in MOTOR neurons are in the axon hillock and in SENSORY neurons, they're in the 1st unmyelinated area (first node of ranvier).
The critical point is called the point at which a function's derivative is zero or undefined. At this point, the function may have a local maximum, minimum, or an inflection point.
neurotransmitters
no, synapse. node of ranvier is between axon and dendrites

The substance that is released at an axonal ending to propagate the nerve impulse to the next nerve or muscle is called
