Axon

An axon is a single extension of a neuron that transmits nerve impulses from the cell body to other neurons, muscle fibers, or cells. This nerve fiber can reach more than one meter in length in some neurons.

Most axons are covered by a myelin sheath, which consists of a multifold double layer of Schwann cell plasma membrane. The myelin sheath is an insulator that helps speed up the transmission of nerve impulses.

At the border between two neighboring Schwann cells, a node of Ranvier is formed, which is the site of the most concentrated ion channel activity. This allows nerve impulses to be transmitted faster.

The axon ends in a telodendron - many terminal branches that contact other nerves, muscle fibers or cells. These contacts form at synapses, allowing information to be transferred from one cell to another.

The axon is an important part of the nervous system and plays a key role in transmitting information between neurons, muscle fibers and cells. Understanding the structure and function of the axon helps to better understand how the nervous system works and what mechanisms underlie neuropathological diseases.



An axon is a nerve fiber, which is a single process extending from the body of a neuron and transmitting a nerve impulse from it. In some cases, the axon can be more than one meter long. Axons are covered with a myelin sheath, which is a multifold layer of plasma membrane. At the border between Schwann cells that surround the axon, a node of Ranvier is formed. The axon ends with many terminal branches - telodendria, which are in contact with nerve cells or muscle fibers. Telodendra transmit nerve impulses from the axon to other cells and provide communication between neurons.



An axon is a nerve process in the body that ensures the transmission of nerve impulses from one nerve cell to another. These fibers can be up to one meter long in some types of neurons.

The main components of an axon are the nucleus, cytoplasm, mitochondria, organelles, ribosomes and nucleolus. The nucleus is responsible for storing genetic information necessary for the synthesis of proteins and cells. Cytoplasm is the semi-liquid content of the cell and contains all the organelles, including the organelles and the nucleus. Mitochondria provide cells with energy by oxidizing nutrients. Ribosomes are responsible for the synthesis of many cellular proteins. And nucleoli take part in the assembly of ribosomal subunits.
