Collaterals are branches that sometimes occur along the length of an axon. Parasympathetic branch is the branch of the autonomic nervous system causes increased secretion by digestive glands.

Signals are transmitted along the axon at the axon terminals or synaptic boutons. These structures are located at the ends of axon branches and contain neurotransmitter-filled vesicles that are released into the synapse to communicate with neighboring cells.
The axon is supported from within by microtubules, which are part of the cytoskeleton. Microtubules provide structural support and help in the transport of molecules and organelles along the length of the axon.
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.

The side branches of the axon are called axon collaterals. They are smaller branches that extend from the main axon and allow for communication with multiple target cells simultaneously. Axon collaterals play a key role in neural communication and signal transmission.
Cell nucleus and free ribosomes are structures that are not found in the axon. The axon is a long, slender projection of a nerve cell that lacks these organelles to allow for efficient transmission of electrical signals along its length.
If a motor neuron in the body were stimulated by an electrode placed about midway along the length of the axon, the action potential would be generated and propagate both towards the cell body and towards the axon terminals. The direction of the action potential propagation is determined by the all-or-none principle, meaning that once initiated, the action potential will travel the length of the axon in both directions.
The nodes Ranvier are spaced equally along the axon because of their function which is to transmit information to the different glands, muscles and neurons. The axon is also called a nerve fiber.
Small distal branches of an axon are called axon terminals or synaptic terminals. These structures are specialized endings of the axon that release neurotransmitters to communicate with other neurons or muscle cells. The axon terminals facilitate the transmission of signals between neurons at synapses.
Action potentials occur along the axon of a neuron, where the electrical signals are transmitted from the cell body to the axon terminals. The action potential is initiated at the axon hillock and propagates down the axon to trigger the release of neurotransmitters at the synapse.
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
