What is the fiber in a neuron that carries signals away from the cell body?
The fiber in a neuron that carries signals away from the cell body is called the axon. Axons transmit electrical impulses, known as action potentials, to other neurons, muscles, or glands. They can be quite long and are often covered by a myelin sheath, which helps increase the speed of signal transmission.
What fiber transmits impulses to the central nervous system?
The fiber that transmits impulses to the central nervous system is called an afferent or sensory fiber. These fibers carry sensory information from receptors in the body to the brain and spinal cord, allowing for the perception of different sensations like touch, temperature, and pain.
What is the hairlike fiber that carries nutrients to the non-vascular plants?
rhizoid
Is fiber same as axon?
No, fiber refers to any thread-like structure in the body, while axon specifically refers to the long extension of a nerve cell that conducts electrical impulses. Axons are a type of fiber found in the nervous system.
What are components of a nerve fiber?
A nerve fiber consists of the axon, which transmits nerve impulses, along with protective covering called myelin sheath, Schwann cells that produce myelin, and the endoneurium which surrounds individual nerve fibers.
What is the fiber tract that carries impulses to the cerebrum and then to the lower CNS called?
The fiber tract that carries impulses to the cerebrum and then to the lower CNS is called the corticospinal tract. It is involved in voluntary motor control and starts from the primary motor cortex in the cerebrum and descends to the spinal cord.
What is a long nerve fiber that carries impulses from one nerve cell to the next called?
an axon
A long nerve fiber that carries impulses from one nerve cell to the next?
It's called an axon.
Does an unmyelinated fiber conduct impulses faster than a myelinated fiber?
False

Is fiber optic immune to electromagnetic interference and radio frequency interference?
Yes. It is immune to EMF (electromagnetic interference) and does not create its own EMI. Also, it is immune to RFI, or radio frequency interference. This is because fiber optic carries signals as light waves instead of electrical impulses.
What fiber transmits impulses to the central nervous system?
The fiber that transmits impulses to the central nervous system is called an afferent or sensory fiber. These fibers carry sensory information from receptors in the body to the brain and spinal cord, allowing for the perception of different sensations like touch, temperature, and pain.
Cable that carries signal?
fiber optics
Microscopic fiber that carries the nervous impulse along nerve cell?
Some nerve cells have fibers that grow out of the cell, which are called axons. Axons allow a nerve cell to connect to distant parts of the body, so that cells in the brain can send messages to, and receive messages from a toe, for example, which might be six feet away from the brain. Other nerve cells just connect to their immediate neighboring nerve cells, and therefore do not require axons; they instead have smaller extensions called dendrites.
Which nerve fiber do impulses travel slowly?
Unmyelinated nerve fibers conduct impulses more slowly than myelinated nerve fibers. Myelinated nerve fibers have a fatty substance called myelin sheath that allows for faster transmission of impulses compared to unmyelinated fibers without this sheath.
A fiber tract that provides for communication between the cerebrum and the CNS area?
If the fiber tract connects the cerebral cortex and the lower brain or spinal cord then it is referred to as a projection tract.
Mechanism of nerve conduction?
Nerve conduction involves the transmission of electrical impulses along the length of a nerve fiber. When a nerve is stimulated, sodium ions rush into the nerve cell, causing a change in electrical charge. This creates an action potential that travels down the nerve fiber, activating adjacent areas and allowing the signal to be transmitted. Once the impulse reaches its destination, neurotransmitters are released to stimulate the next nerve cell or muscle fiber.
