Nerve impulse transmission is the process by which neurons communicate with each other through electrical and chemical signals. This involves the generation of an action potential, its propagation along the axon, and the release of neurotransmitters at the synapse to relay the signal to the next neuron.

Nerve Impulse Transmission

Nerve impulse transmission

Neurons are the fundamental units of the brain and nervous system, responsible for receiving sensory input, processing information, and transmitting signals to other neurons, muscles, or glands. They communicate through electrical impulses and chemical signals, forming complex networks that underpin all cognitive and physiological functions.

Electrical signals are the means by which information is transmitted across various systems, both biological and technological, allowing for communication and control. They are characterized by their amplitude, frequency, and phase, and are essential in fields ranging from neuroscience to telecommunications.

Electrical Signals

chemical signals

An action potential is a rapid, temporary change in the electrical membrane potential of a neuron or muscle cell, allowing it to transmit signals over long distances. This process involves the sequential opening and closing of voltage-gated ion channels, resulting in depolarization and repolarization of the cell membrane.

release of neurotransmitters

A synapse is a specialized junction between neurons that facilitates the transmission of electrical or chemical signals, playing a crucial role in neural communication and brain function. It involves complex processes of neurotransmitter release, receptor binding, and signal propagation, which are essential for learning, memory, and overall nervous system operation.
