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 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.
Which cell process are not myelinated?
According to McGraw Hill (please see related link below): Many nerve fibers in the CNS and PNS are unmyelinated. In the PNS, however, even the unmyelinated fibers are enveloped in Schwann cells. In this case, one Schwann cell harbors from 1 -12 small nerve fibers in grooves in its surface. The Schwann cell's plasma membrane does not spiral repeatedly around the fiber as it does in a myelin sheath, but folds once around each fiber and somewhat overlaps itself along the edges. This wrapping is the neurilemma (also called a mesaxon in unmyelinated nerve fibers). Also, gray matter of the brain and dendrites are unmyelinated, while axons are myelinated.
When was PNS Azmat created?
PNS Azmat was created on 2012-04-24.
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?
NERVES
Difference between optic tract and optic nerve?

What is the name for bundles of myelinated axons in the PNS?
nerves
What is a group of axons bundled together coated in myelin that travels together through the body called?
Its called a tract; while a bundle of axons in the PNS is called a nerve
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 the organs of the nervous system work together?

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 are the nerve cells that carry signals from the central nervous system to the muscles or glands?
Motor (efferent) division of PNS carries motor responses from the central nervous system to muscles, glands, and other organs.Response by the nervous system is accomplished by motor control.Neurons send impulses to the spinal chord and dendrites carry the message to the cell body the axons then sends them awayMotor neuronsefferent neurons

What are 2 main parts of nervous system?
The central nervous system (CNS) and the peripheral nervous system (PNS)
