What else can I help you with?
In which division of the nervous system would nerve regeneration be unlikely to occur?
In the central nervous system (CNS), which includes the brain and spinal cord, nerve regeneration is unlikely to occur due to limited regenerative capacity and the presence of inhibitory factors that hinder nerve growth. Conversely, in the peripheral nervous system (PNS), nerve regeneration is more possible, as peripheral nerves have a greater ability to regenerate under certain conditions.
Does the PNS lack endoneurium?
No, the peripheral nervous system (PNS) does contain endoneurium. Endoneurium is the connective tissue that surrounds individual nerve fibers within a nerve bundle. It provides support and protection to the nerve fibers in the PNS.
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 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.
The postganglionic receptors for the pns are muscarine?
Actually, the postganglionic receptors for the parasympathetic nervous system (PNS) are predominantly muscarinic receptors. These receptors are activated by acetylcholine released from postganglionic parasympathetic nerve terminals.
In which division of the nervous system would nerve regeneration be unlikely to occur?
In the central nervous system (CNS), which includes the brain and spinal cord, nerve regeneration is unlikely to occur due to limited regenerative capacity and the presence of inhibitory factors that hinder nerve growth.

Does the PNS lack endoneurium?
No, the peripheral nervous system (PNS) does contain endoneurium. Endoneurium is the connective tissue that surrounds individual nerve fibers within a nerve bundle. It provides support and protection to the nerve fibers in the PNS.
Is regeneration within the CNS more successful than with PNS?
YES
The specialized cells of the PNS that are surrounded by a basement membrane that is capable of forming a regeneration tube through which a severed peripheral axon can regrow are the?
Schwann cells are the specialized cells in the peripheral nervous system (PNS) that are capable of forming a regeneration tube to guide a severed peripheral axon during the process of regeneration. This process allows for potential regrowth and repair of damaged nerves in the PNS.
Which ganglion is unipolar?
The afferent nerve of the PNS have the pseudounipolar cells.
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.
Does the CNS nerve fibers lack the intrinsic capacity to regenerate while PNS nerve fibers are able to regenerate?
Yes
Cranial nerves part of what nervous system?
PNS means peripheral nervous system. CNS means central nervous system.
What is a group of axons bundled together coated in myelin that travels together through the body called?
A group of axons bundled together and coated in myelin that travel together through the body is known as a nerve fiber or a nerve tract. These nerve fibers facilitate the transmission of electrical impulses from one part of the body to another.
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.
What is a word for nerve cell bodies outside CNS?
ganglia is a group of cell bodies in the PNS.
The postganglionic sympathetic fiber originates from?
The postganglionic sympathetic fiber originates from PNS within a ganglion
