What else can I help you with?
What two cells form the insulating sheaths around axons?
Schwann cells and oligodendrocytes
Does oligodendrocytes serve the same purpose in the central nervous and periphial nervous system?
No, they form myelin sheaths on axons in the CNS while schwann cells form myelin sheaths in the PNS. Hope this answers your question.
What is the plural of sheath?
The plural of sheath is sheaths. As in "the knight sheaths his sword".
Formed by schwann cells in the PNS?
Schwann cells in the peripheral nervous system form myelin sheaths around axons, which helps to speed up the transmission of nerve impulses. These myelin sheaths act as insulating layers that ensure efficient communication between neurons.
Which of the following PNS neuroglia help to form myelin sheaths around larger nerve fibers in the PNS?
The Schwann cells in the peripheral nervous system (PNS) help to form myelin sheaths around larger nerve fibers. These cells wrap around the nerve fibers to provide insulation and support for faster nerve impulse conduction.
What is the prefix for Neuralgia?
There is no prefix in the term "neuralgia". Neur/o = combining form meaning nerve(s). -algia = suffix meaning pain or painful condition.
What PNS neuroglia help to form myelin sheaths around larger nerve fibers in the PNS?
In the peripheral nervous system, Schwann cells are responsible for forming myelin sheaths around the larger nerve fibres in the PNS. Keep in mind that one Schwann cell myelinates one nerve. You may hear about oligodendrocytes, but these are responsible for myelination in the Central Nervous System, and myelinate multiple nerves.
Would Trigeminal Neuralgia cause a hard lump to form in front of ear?
no
What are the neuralgia that wrap around capillaries helping to form the blood brain barriers?
Astrocytes
Which neuroglial cell is responsible for the production of myelin sheaths around axons in the central nervous system?
Oligodendrocyte; processes of the oligodendrocytes form the myelin sheaths around the CNS nerve fibers
What is the medical terminology combining form meaning pain?
- algia?. e.g. neuralgia. (Painkiller = analgesic)
Do neurotransmitters form the myelin sheath?
No, not at all. The myelin sheaths are actually made by other living cells in the nervous system known as glia. Two types of glia myelinate the nervous system: oligodendrocytes and Schwann cells. The oligodendrocytes for myelin in the central nervous system (brain and spinal cord) and the Schwann cells form myelin in the peripheral nervous system (everything outside the brain and spinal cord).
