What are nerve axon tracks made of?
The axons of nerve cells are surrounded by myelin sheeths - a protective covering that allows for saltatory conduction down the axons, increasing speed and decreasing loss of signal. Axons make up the tissue known as "white matter."
Are axons most located and protected within the CNS?
axons
Is a nerve an organ?
Yes nerve is an organ of nervous system ., Each nerve is a cordlike structure that contains many axons. These axons are often referred to as 'fibres'. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium.
Axons that are much slower than axons coated with 19 down?
i have the same crossword right in front of me! its demyelinated
The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina

Area of spinal cord that contains nerve fibers surrounded by myelin sheath?
the part of the spinal cord that contains mylinated axons is the White matter portion.
Are axons most located and protected within the CNS?
axons
Why are some axons surrounded by myelin sheaths?
Nerve impulse is an electrical current, which flows across the axons. So most of the neurons are surrounded by myelin sheath. This sheath gives insulation to the axons. Brain can not function without this insulation.
What is a group of axons bundled together called?
a nerve is bundled together by neuron fibers. The CELL BODY OF A NERVE or neuron is surrounded by satellite cells.
Can oligodendrocytes myelinate several axons?
yes TRUE

What axons do nerves contain?
Nerves are like trees. The have branches call axons.
Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project directly to the
What is another name for Myelinated axons?
In preserved brains, the myelinated axons look white. Therefore, what we call "white matter" is typically made of axons.
What are Bundles of axons are called?
NERVES
Why is there fat coating around the dendrites and axons?
The fat coating around the dendrites and axons is to insulate them.
