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."

Nerve axon tracks are made of bundles of axons, which are the long, slender projections of nerve cells that transmit electrical signals throughout the nervous system. These axon tracks are covered and insulated by a substance called myelin, which helps to speed up the transmission of nerve impulses. The axon tracks are organized in a way that allows for efficient communication between different parts of the nervous system.

What does the nerve cell include?
The nerve cell can be thought of as just the nerve body, which is the main part of the nerve cell. The nerve cell is also known as a neuron. The entire neuron includes an axon, nerve body, dendrites, and axon terminals.
Can a nerve fiber survive without its cell or its axon?
No, a nerve fiber cannot survive without its cell body or axon. The cell body provides nutrients and support to the axon, while the axon is responsible for transmitting signals. Without either of these components, the nerve fiber would no longer function.
What influences the speed of a nerve impulse?
the diameter of an axon
What part of nerve cell is adjacent to neuromuscular junction?
The axon terminal of a nerve cell is adjacent to the neuromuscular junction. The axon terminal releases neurotransmitters that transmit signals across the synapse to the muscle fiber. This signal triggers muscle contraction.
What is an axon made up of?
An axon is made up of a single elongated fiber that carries electrical impulses away from the cell body of a neuron. It is surrounded by a myelin sheath, which is made up of fatty substances and acts as an insulator to facilitate the rapid transmission of nerve signals. The axon also contains microtubules, neurofilaments, and other proteins that help maintain its structure and support its function.
What is the difference between a nerve dendrite and a nerve axon structurally?
The nerve axon is the main nerve from where the dendrites originate.
Axon is what?
An axon (or axone) is a nerve fibre which is a long, slender projection of a nerve cell, which conducts nerve impulses away from the body of the cell to a synapse.
What composed of a cell bodydendritesand axon?
Nerve cell or neuron

What is the name of the area where nerve impulses arises?
receptive region?
How can you the word axon in a sentence?
The axon carries nerve impulses away from the cell body.
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of neurons. They store and release neurotransmitters during synaptic transmission in order to pass signals to other neurons or target cells.
What are the parts of a nerves?
the parts of the nerve cell are cell body,dendrites,and axon, axon teminals, nucleus,
What are highly branched parts of the nerve cells?
axon
A nerve impulse starts at the dendrite then travels to the?
cell body, continues down the axon, and finally reaches the axon terminal. At the axon terminal, the impulse triggers the release of neurotransmitters to communicate with other neurons or muscles.
What influences the speed of a nerve impulse?
the diameter of an axon
