Which type of cell produces the myelin covering around the axon of a neuron?
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
What type of tissue Contains schwann cells?
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
What is the name of covering of axon?
Because this is tissue from the brain (CNS), it is an oligodendrocyte which wraps around axons of neurons in the CNS to form a fatty myelin sheath. If it were PNS axons in say spinal or cranial nerves, the answer would be be Schwann cells.
What specialized cells are wrapped in axons and dendrites?
Specialized cells wrapped in axons and dendrites are primarily neurons. Neurons have long projections called axons that transmit electrical signals away from the cell body, while dendrites receive signals from other neurons. These structures are crucial for communication within the nervous system, allowing for the transmission of information across synapses. Glial cells, such as oligodendrocytes and Schwann cells, also wrap around axons, providing insulation and support.
Do schwann cells act as insulators?
Yes, Schwann cells act as insulators in the peripheral nervous system by forming the myelin sheath around axons. This myelination enhances the speed of electrical signal transmission through a process called saltatory conduction, where impulses jump between nodes of Ranvier. By insulating the axons, Schwann cells also help to protect and maintain the health of peripheral neurons.
What are swann cells?
Schwann cells are cells that surround the axons (nerve fibre) of neurons providing the myelin sheath. They are associated with neurons in the peripheral nervous system.
Do schwann cells produce myelin shealths that cover the axons of neurons?
Yes, Schwann cells are responsible for producing the myelin sheath that covers the axons of peripheral neurons. This insulation helps to speed up the transmission of electrical signals along the axon.
What cells in the peripheral nervous system that form a covering around axons?
Schwann cells wrap around the AXONS of peripheral neurons.
Which type of cell produces the myelin covering around the axon of a neuron?
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
How do you create myelenated neurons?
You don't, but glial cells, (oligodendrocytes in the CNS, and Schwann cells in the PNS), wrapped one after another around the axons of neurons with gaps between them called the nodes of Ravnier do create myelinated neurons.
What is the specialized cells that myelinate the fibers of neurons found in the peripheral nervous system?
The specialized cells that myelinate the fibers of neurons in the peripheral nervous system are called Schwann cells. Schwann cells wrap around the axons of neurons to form the myelin sheath, which helps to insulate and protect the nerve fibers, allowing for faster and more efficient conduction of nerve impulses.
What type of tissue Contains schwann cells?
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
What is the purpose of myelin sheath?
This is a process that occurs in the CNS and PNS with axons. In the CNS oligodendrocytes surround the axons and in PNS schwann cells surround the axons. the myelin sheath will increase the speed of nervous conduction along the axon.
What supports the cells of nervous system?
glial cells (sometimes called neuroglia).In the peripheral nervous system, Schwann cellsform a myellin sheath around axons, and in the central nervous system, Oligodendrocytes do the same thing for the neurons there; and Astrocytes (Astroglia) surround brain neurons to hold them in place, provide nutrients and oxygen to them, insulate neurons from one another, destroy pathogens and remove dead neurons, and possibly in some ways modulate neurotransmission.

Which best describes the components of a nerve?
axons, blood vessels, connective tissue, Schwann cell.
