One type of neuroglial cell not found in the central nervous system (CNS) is the Schwann cell. Schwann cells are responsible for myelinating peripheral nerves in the peripheral nervous system (PNS). In contrast, oligodendrocytes serve a similar function in the CNS by myelinating axons. Thus, while Schwann cells are crucial for peripheral nerve function, they do not exist in the CNS.
What else can I help you with?
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 cell cell that myelinates and insulates axons within the CNS is the?
Oligodendrocyte
An autonomic motor neuron whose cell body lies in the CNS is called a?
This type of nerve is called an efferent autonomic neuron.
What cells make up the mylin sheath?
There are two cells that are involved in the myelin sheath. One type is found in the central nervous system (CNS) and the other is in the peripheral nervous system (PNS).These are the oligodendrocytes (CNS) and Schwann cells (PNS).
Where are the nerves and ganglia structures found?
Nerves and ganglia structures are primarily found in the peripheral nervous system (PNS). Nerves are bundles of axons that transmit signals between the central nervous system (CNS) and the rest of the body, while ganglia are clusters of nerve cell bodies located outside the CNS, serving as relay points for nerve signals. Additionally, within the CNS, there are similar structures, such as nuclei, which serve comparable functions to ganglia.
Collection of nerve cell bodies found outside CNS?
In the peripheral nervous system, which is outside the central nervous system (CNS), collections of nerve cell bodies are called ganglia.
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
Collection of cell bodies found outside the cns?
The collection of cell bodies found outside the central nervous system is known as a ganglion. Ganglia are clusters of nerve cell bodies located along the peripheral nerves and are involved in transmitting sensory information to the central nervous system and coordinating motor responses.
What cell cell that myelinates and insulates axons within the CNS is the?
Oligodendrocyte
An autonomic motor neuron whose cell body lies in the CNS is called a?
This type of nerve is called an efferent autonomic neuron.
Name the specific myelinating cell of the CNS?
Oligodendrocyte
Which of the following does not respond to cell-mediated immunity?
pathogens in the CNS
What is a word for nerve cell bodies outside CNS?
ganglia is a group of cell bodies in the PNS.
What type of precuation is needed with CNS depressants?
Most CNS depressants have the potential to be physically and psychologically addictive.
What are the two cell populations in the body that do not undergo cell division?
Neurones in the CNS and cardiac/myocardial cells.
What cells make up the mylin sheath?
There are two cells that are involved in the myelin sheath. One type is found in the central nervous system (CNS) and the other is in the peripheral nervous system (PNS).These are the oligodendrocytes (CNS) and Schwann cells (PNS).
What is the job of the oligodendrocyte?
Oligodendrocytes are a type of glial (supporting) cell in the brain that sends out cytoplasmic extensions to insulate axons in the central nervous system. This allows for greater speeds of nervous impulses between the brain and a sensory receptor or between two neurons ("brain" cells).
