Macrophages will remove the debris of the myelin

sheath and other cellular items. The axon may begin to regrow into a tube that is created by remaining membrane and connective tissue, having been influenced by the nerve growth factors that comes from neuroglial

cells that are nearby. At the same time, remaining Schwann

cells will multiply and form a new myelin

sheath around the axon.

Axons can regenerate through a process called axonal sprouting, where new branches form on the damaged axon. This process is often guided by growth-promoting molecules in the surrounding environment, and specialized cells called Schwann cells play a crucial role in facilitating axon regeneration. However, the success of axon regeneration can vary depending on factors such as the extent of the damage and the presence of inhibitory factors in the environment.

Neurons are amitotic- they do not reproduce. However, research has been done on the production of new neurons in adults from neural stem cells (adult neurogenesis).

Neurons are the only cells in the human body that cannot regenerate.

Hence brain damage of any sort is irreversible, and permanent.

No, ovaries do not regenerate. Unlike some tissues in the body, ovaries do not have the ability to regenerate or regrow once damaged.


What is the bundle of axons called in the CNS?

Axons and dendrites that go to or from the same region of the body travel together in bundles, somewhat like telephone cables. A nerve is a bundle of axons and/or dendrites in the PNS. A bundle of axons and/or dendrites in the CNS is called a tract.for more info see link below

Does the parasympathetic division have long preganglionic axons and a short ganglionic axon?

Yes, the parasympathetic division typically has long preganglionic axons and short ganglionic axons. The ganglia of the parasympathetic division are typically located near or within the target organ, leading to short postganglionic axons.


Axons and dendrites?

Axons are responsible for transmitting electrical signals away from the neuron cell body. Dendrites, on the other hand, receive incoming signals from axons of other neurons. Together, axons and dendrites play a crucial role in the communication between neurons in the nervous system.
