What are Bundles of axons are called?
NERVES
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 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
Sensory neurons of the PNS are?
Unipolar Sensory Neurons: large myelinated neurons with the cell body off to one side of the single dendritic-axon process. Multipolar Motor Neurons: large myelinated neurons that have many dendrites off the cell body and an axon that may branch to effect many effectors.
Bundles of axon within a nerve?
Neuron processes running through the CNS form tracts of white matter; in the PNS they form the peripheral nerves.

NERVES
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns

Are nerves more myelinated or unmyelinated in the CNS?
Nope. They can be found in the PNS as well. The myelinated ones in the CNS are made my Schwann cells. And the ones made in the PNS are made by oligodendrocytes.
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 are bundles of fibers that connect the CNS with the rest of the body?
Bundles of fibres running between the Central Nervous System (CNS) and all the tissues of the body are called Nerves. These nerves make up the Peripheral Nervous System (PNS). The correct name for the fibres in these bundles is Axons which are the long part of neuron cells carrying the signal from the cell body to the Target Tissue.
Groups of axons and dendrites in the PNS are called?
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
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 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.
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.
