The peripheral nervous system.
Nerve tissue is specialized to conduct electrical signals (impulses) from one part of the body to another. Nerve cells, or neurons, have unique properties that allow them to transmit these signals through a combination of electrical and chemical processes.
The specialized cell in the nervous system that conducts signals is called a neuron. Neurons are responsible for receiving, processing, and transmitting information through electrical and chemical signals.
Neurons use electrochemical signals to send any kind of information through the body.
In metals, the mobile electrons are responsible for conducting signals. These electrons can move freely within the metal lattice, allowing for the efficient flow of electrical currents necessary for signal conduction.
The conduction of electrical signals is fastest in neurons that are myelinated. Myelin acts as an insulating layer around the axon, allowing the electrical signals to jump from one node of Ranvier to another in a process known as saltatory conduction, increasing the speed of signal transmission.
Dendrite toward the cell body, axon away from the cell body.
Electrical signals are transmitted from one place to another through conductive materials, such as copper wires. These materials provide a path for the signals to travel, and the signals are modulated to carry information. In some cases, signals can also be transmitted wirelessly through electromagnetic waves.
Nervous tissue conducts messages (nerve impulses) throughout the body. It is made up of neurons that transmit electrical signals and support cells called glial cells. This allows for rapid communication between different parts of the body.

With analog and digital signals.
The cochlea turns vibrations into electrical signals that are then sent to the brain via the auditory nerve. These electrical signals are interpreted by the brain as sound.
Electrotonic conduction helps propagate signals in neurons by allowing electrical signals to passively spread along the neuron's membrane. This process involves the movement of charged ions, such as sodium and potassium, which creates an electrical gradient that helps transmit signals from one part of the neuron to another.
