NEURONAL CELL Meaning and
Definition
-
A neuronal cell, also commonly referred to as a neuron, is a fundamental unit of the nervous system responsible for transmitting electrical signals and facilitating communication between different parts of the body. Neuronal cells are specialized cells that play a crucial role in the processing and integration of information in the brain, spinal cord, and peripheral nervous system.
Structurally, a neuronal cell consists of a cell body, dendrites, and an axon. The cell body contains the nucleus and other organelles, such as mitochondria and ribosomes, necessary for cellular functions. Dendrites are branched extensions originating from the cell body that receive electrical signals from other neurons and transmit them towards the cell body. The axon, on the other hand, is a long, slender extension responsible for transmitting these electrical signals away from the cell body and towards other neurons or target cells.
The function of a neuronal cell is primarily related to its ability to communicate and transmit signals. When activated, electrical impulses called action potentials are generated in the cell body and travel down the axon, rapidly transmitting information to other neurons or effector cells, such as muscle fibers or glands, by releasing chemical messengers called neurotransmitters at specialized junctions called synapses.
Neuronal cells vary in size, shape, and function depending on their location within the nervous system. They are responsible for processes such as sensory perception, motor control, memory formation, and cognitive functions, which are essential for the proper functioning of the nervous system and overall organism.

Etymology of NEURONAL CELL
The term "neuronal cell" is a combination of two words: "neuronal" and "cell". Each has its own etymology:
1. Neuronal: The word "neuronal" is derived from the Greek word "neuron", meaning "nerve". "Neuron" comes from the Greek word "neuron", which originally referred to "sinew" or "tendon". The meaning later expanded to refer to the nerves extending from the brain and spinal cord, thus leading to the modern concept of neurons.
2. Cell: The word "cell" has Latin origins, derived from the Latin word "cella", meaning "small room" or "storeroom". It was initially used in biology to describe the small compartments observed in organisms under a microscope. Over time, the term "cell" has become commonly used to refer to the basic structural and functional unit of all living organisms.
