ome axons can extend up to one meter or more while others extend as little as one millimeter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot.
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 100 billion neurons. To learn how neurons carry messages, read about the action potential.  An axon (from Greek ἄξων axōn, áxōn), axis is a, long slender projection of a nerve, cell or, neuron that typically conducts electrical impulses away from the'neuron s cell. body Some axons can extend up to one meter or more while others extend as little as one millimeter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across). 1 The DRG is the longest axon in the human body. 2  Humans are mammals. 3  The (confirmed) largest and longest animal to have ever lived is the blue whale. 4  Blue whales are also mammals and thus have nervous systems roughly equivalent to humans. Note that for the sensations in the toes, this means that the axon goes all the way from the toe to the medulla, which is at about the same height as the mouth. This can be more than 2 meters long in tall people. That's a long axon! How long is the longest axon in the world? About 15 feet, its the sciatic nerve that runs from the base of the spinal cord to the big toe. Answer     The axons are long so that action potentials can be sent from one part of the body to another very quickly. An axon (from Greek ἄξων axōn, áxōn), axis is a, long slender projection of a nerve, cell or, neuron that typically conducts electrical impulses away from the'neuron s cell. Body myelinated axons are known as nerve. fibers Some axons can extend up to one meter or more while others extend as little as one millimeter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across). The largest blue whales are around 30 m long. This would suggest a DRG axon of at least 25 m, or 75 feet, long. Here's where it gets nuts and things stop making sense to me... Axons typically conduct signals between a wide range of speeds: 0.5 to 100 m/s. 1  The DRG is the longest axon in the human body.

This can be more than 2 meters long in tall people. That's a long axon! Answers. Relevance. Rating Newest Oldest.
