Nerve cells, or neurons, can range from .004 millimeters to .1 millimeters in diameter. Their length can be anywhere from a fraction of an inch to several feet long, depending on nerve cell type. Nerve cells can transmit nerve signals to and from the brain at speeds up to 200 miles per hour.


Thanks for A2A… There are many type of neurons. They vary in size from 4 microns (.004 mm) to 100 microns (.1 mm) in diameter. Their length varies from a fraction of an inch to several feet. Neurons are nerve cells that transmit nerve signals to a...


A neuron, also known as a neurone (British spelling) or nerve cell, is an electrically excitable cell that communicates with other cells via specialized connections called synapses. It is the main component of nervous tissue. All animals except sponges and placozoans have neurons, but other multicellular organisms such as plants do not.


The average size of a human cell varies quite a lot. a single nerve cell can be up to a meter long while a cheek cell averages about 50 micrometers or .05 mm. the average cell though is between 10 ...


The longest human cell are nerve cells in the human body. Some of them run the length of the spine all the way to the toes and may be as long as 1.5m in length.


A human is, according to the most recent estimates, an assortment of 3.7±0.8×10 13 cells (BNID 109716), plus a similar complement of allied microbes. The identities of the human cells are distributed amongst more than 200 different cell types (BNID 103626, 106155) which perform a staggering variety of functions.


Neuroscience For Kids . Types of Neurons (Nerve Cells) The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 86 billion neurons.

GLIAL CELLS. Glial cells make up 90 percent of the brain's cells. Glial cells are nerve cells that don't carry nerve impulses. The various glial (meaning "glue") cells perform many important functions, including: digestion of parts of dead neurons, manufacturing myelin for neurons, providing physical and nutritional support for neurons, and more.


Nerve Cell Many nerve cells are of the basic type illustrated above. Some kind of stimulus triggers an electric discharge of the cell which is analogous to the discharge of a capacitor.This produces an electrical pulse on the order of 50-70 millivolts called an action potential.The electrical impulse propagates down the fiber-like extension of the nerve cell (the axon).
