The Axons
In the central nervous system (CNS), there are two main types of neuron fibers: afferent (sensory) fibers that carry information from sensory receptors to the CNS, and efferent (motor) fibers that carry information from the CNS to effectors such as muscles and glands. These fibers make up the vast network of connections that allow for communication within the brain and spinal cord.
It is a bundle of neurons, all flowing from the same general source (the eye) to the optic chiasm.
White matter is organized into ascending and descending tracts called pathways. These pathways consist of bundles of nerve fibers that transmit signals between different regions of the central nervous system. The ascending pathways carry sensory information towards the brain, while the descending pathways carry motor commands from the brain to the muscles and glands.
No, the afferent division of the peripheral nervous system (PNS) does not carry motor fibers. Instead, it is responsible for transmitting sensory information from sensory receptors to the central nervous system (CNS). Motor fibers are part of the efferent division of the PNS, which carries signals from the CNS to muscles and glands to elicit a response.
The Axons
False. Afferent fibers carry sensory information from the peripheral nerves to the central nervous system, such as information about touch, pain, temperature, etc. Efferent fibers, on the other hand, carry signals from the central nervous system to the muscles to initiate movement.

Usually they are simply called nerves. Depending on the scenario, sometimes they are called nerve tracts or pathways.
The bundles of neurons that transmit impulses over long distances are called nerves. Nerves are composed of axons, which are the long fibers that carry electrical impulses from one part of the body to another.

Infrared & Microwaves are used to carry information through Optical Fibres. Infrared carries visible light Radio Waves & Microwaves carry telephony and computed data E.Akbay
The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
There are three main types of nerve fibers: sensory, motor, and mixed. Sensory fibers carry information from the body to the brain, motor fibers carry signals from the brain to the muscles, and mixed fibers can do both. These fibers work together to transmit signals throughout the nervous system, allowing for communication between the brain and the rest of the body.
No. Nerves are not blood-filled. They are a bundle of fibers that carry information from parts of your body back to your brain, where your brain then processes that information.
Typically, light in the form of laser beams is used to carry information through optical fibers. The laser light pulses encode data that is transmitted through the fibers in the form of light signals.
