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.
What else can I help you with?
The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
Are axons most located and protected within the CNS?
axons
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.
Are unmyelinated axons in the cerebral cortex?
Yes, unmyelinated axons are present in the cerebral cortex. While many neurons in the cerebral cortex have myelinated axons, some interneurons and shorter local circuit neurons have unmyelinated axons. These unmyelinated axons play a role in the local processing and communication within the cortex.
What 3 factors influence whether axons and dendrites can repair themselves?
Three key factors that influence the repair of axons and dendrites are the type of nervous system (central vs. peripheral), the presence of growth factors, and the intrinsic properties of the neurons themselves. In the peripheral nervous system, axons have a greater capacity for regeneration due to supportive cells like Schwann cells, which promote growth. In contrast, the central nervous system has more inhibitory molecules and a less favorable environment for repair. Additionally, the age and health of the neuron, including its ability to regenerate and form new connections, play a crucial role in the repair process.
Can axons regenerate after encephalitis?
Axons can regenerate after encephalitis, but the extent of regeneration depends on various factors, including the severity of the damage and the specific areas of the nervous system affected. In the central nervous system, axonal regeneration is limited due to the inhibitory environment created by glial cells and the formation of scar tissue. However, in the peripheral nervous system, axons have a greater capacity for regeneration, aided by supportive Schwann cells. Rehabilitation and therapeutic interventions can also play a crucial role in promoting recovery.
How do the conduction velocities of unmyelinated axons compare to myelinated axons?
Unmyelinated axons have slower conduction velocities compared to myelinated axons. Myelinated axons are able to conduct nerve impulses faster due to the insulation provided by the myelin sheath.
Do axons send or receive signals?
Axons send signals.
Do frogs regenerate?
frogs do regenerate
What axons do nerves contain?
Nerves are like trees. The have branches call axons.
Do lizards regenerate themseves?
the answer is no but they can regenerate their tails
The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
Can sponges regenerate?
yes they can regenerate. Marine sponges are multicellular animals that can regenerate from single cells.
What is another name for Myelinated axons?
In preserved brains, the myelinated axons look white. Therefore, what we call "white matter" is typically made of axons.
Are axons most located and protected within the CNS?
axons
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
Do ovaries regenerate?
No, ovaries do not regenerate. Unlike some tissues in the body, ovaries do not have the ability to regenerate or regrow once damaged.
