Närvirakku

Närvirakku is a term sometimes used in informal contexts to refer to a nerve cell, also known as a neuron. Neurons are the fundamental building blocks of the nervous system in animals. They are specialized cells responsible for transmitting information throughout the body through electrical and chemical signals. These signals allow for functions such as thought, movement, sensation, and emotion.

A typical neuron consists of a cell body (soma), dendrites, and an axon. Dendrites are branched extensions that receive signals from other neurons. The cell body contains the nucleus and other organelles. The axon is a long projection that transmits signals away from the cell body to other neurons, muscles, or glands. The junction between two neurons where information is transmitted is called a synapse.

Närvirakku, as an informal term, lacks a precise scientific definition and is not commonly used in formal neuroscience literature. The standard and scientifically accepted term for a nerve cell is neuron. Understanding the structure and function of neurons is crucial for comprehending how the nervous system operates and how neurological disorders may arise. The complex network of neurons forms the basis of all nervous system activity.
