DevinNerve 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.
