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."
What are Large bundles of axons and dendrites make up called?
Large bundles of axons and dendrites are called nerves or tracts depending on their location in the central or peripheral nervous system.
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 type of cells make up a plant and how?
Embryonic cells make up a plant
What are the characteristics of axonS?
Axons are long, thin, and cylindrical extensions of nerve cells that transmit electrical impulses away from the cell body to other neurons, muscles, or glands. They are covered by a protective myelin sheath, which helps to speed up the transmission of nerve signals. Axons can vary in length from a few millimeters to over a meter depending on the neuron's location in the body.
What cell makes up the optic nerve?
Not sure, since I'm working on the same assignment, but I think it is ganglion cells. the gagliano cell axons make a right angle turn at the inner face of the retina then leave the posterior aspect of the eye as the thick optic nerve. page 553 marieb&hoehn axons from the ganglion cells run along the internal surface of the retina and converge posteriorly to form the optic nerve. pg 489 human anatomy 5th ed marieb,mallatt,wilhelm
What is the association of axons with nerves?
Axons are long projections of nerve cells that make up nerves. Nerves are bundles of axons transmitting information between the brain, spinal cord, and other parts of the body. Axons are responsible for carrying electrical impulses from one nerve cell to another, allowing for the communication necessary for proper functioning of the 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.
Where do Nodes of Ranvier lie between?
They are more or less equally spaced. The size of the nodes span from 1–2 µm whereas the internodes can be up to (and occasionally even greater than)1.5 millimeters long, depending on the axon diameter and fiber type.
Another name for a bundle of nerve fibers is what?
It is called a dendrite.~

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.
What are the three types of receptor cells in the retina?
Rods and cones are the ones involved in actually seeing. Rods detect mostly black and white, though they might detect some blue. The cones are the color receptors, and they have 3 subtypes to detect long, medium, and short wavelengths of visible light. There is a third type, photosensitive ganglion cells. They are important for entrainment and reflexive responses to the brightness of light..
