Large bundles of axons and dendrites visible to the unaided eye are?
Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What contains myelinated axons?
Myelinated axons are found in the central nervous system (CNS) within areas such as the brain and spinal cord, as well as in the peripheral nervous system (PNS) within nerves outside the CNS. Myelin, a fatty substance produced by glial cells like oligodendrocytes in the CNS and Schwann cells in the PNS, wraps around these axons to insulate and speed up the transmission of nerve impulses.
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.
How the organs of the nervous system work together?
The central nervous system (CNS) includes the brain and spinal cord, while the peripheral nervous system (PNS) includes nerves as well as ganglia (concentrations of nerve cells). Sensory signals travel through ganglia and nerve to the brain, then nerve signals return back to the location of sensory input with a sensation.
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
What are Bundles of axons are called?
Bundles of axons are called nerves. Nerves transmit electrical signals between the brain and other parts of the body.

Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
What is the name for bundles of myelinated axons in the PNS?
The name for bundles of myelinated axons in the peripheral nervous system (PNS) is "nerves." Nerves serve the purpose of transmitting sensory information and motor impulses between different parts of the body and the 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.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
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.

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.
How are nerve cells ensheathed with myelin in the CNS and the PNS?
In the central nervous system (CNS), myelin is produced by oligodendrocytes, which wrap their extensions around the axons of nerve cells. In the peripheral nervous system (PNS), myelin is produced by Schwann cells, which wrap around the axons in a spiral fashion. Myelin sheaths in both systems help to insulate and speed up the transmission of nerve impulses.
