Can you see a nerve cell?

Neurons can only be seen using a microscope and can be split into three parts: Soma (cell body) — this portion of the neuron receives information. It contains the cell’s nucleus. Dendrites — these thin filaments carry information from other neurons to the soma.

Can a nerve cell be a Metre long?

Some neurons are very short… less than a millimeter in length. Some neurons are very long…a meter or more! The axon of a motor neuron in the spinal cord that innervates a muscle in the foot can be about 1 meter (3 feet) in length.

How long is a nerve cell?

The length of a nerve cell can vary from nanometers to meters . Yes, it’s true. Our body is composed of millions to billions of nerve cells. Some nerve cells can be comparatively smaller by 0.1 millimeter or can be longer by 1 meter.

Which cell is up to 1 meter long?

Answer: Nerve cells can be upto one metre long.

Why are nerve cells long?

The major function of nerve cells is to transfer messages in the form of electrical impulses to different parts of the body. Nerve cells are long and have branches because they need more surface area to pass the signals to cell by cell.

Why can’t we see a neuron from naked eye in spite of being 1 meter in size?

Because, their thickness is really really really small. See Neuron. You can see that most of the neurons are at most 10 micrometers thick. That’s really thin for a human eye to see.

What is the longest nerve cell?

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.

Which cell is the longest cell?

nerve cell
– In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.

Why are nerve cells so long ks3?

They are long so they can carry messages up and down the body. Tiny branches (dendrons) which branch further as dendrites at each end. These receive incoming impulses from other neurones.

What makes up a nerve cell?

The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).

Why is nerve cell so long?

Nerve cells are long and have branches because they need more surface area to pass the signals to cell by cell. Their branches structure helps them to receive and transfer messages, thereby helping to control and coordinate the working of different parts of the body.

Why are nerve cells so long in length?

Nerve cells are long because from where they are located in the body to where they extend to, every slitest touch has to be felt everywhere around the human body. Add a Comment user∙ Lvl 2 ∙ 2020-11-17 14:23:36 In a human nerve cell, branches stick off it. Thats why it is so big/long. Add a Comment Add your answer: Earn +20pts

Why are nerve cells so different from other cells?

Well nerve cells are diffrent to other cells mainly because they are very long and thin. This is so nerve signals can travel to the brain quickly. Hope that helps xxx =D Why are nerve cells long and thin? With that shape, nerve cells can transmit messages faster. Why are nerve cells so long and branched out?

How long are nerve cells in a giraffe?

Nerve cells have to be long enough to extend from where they are located in the body, the hands and feet for example, to the spinal chord or brain. Some nerve cells in a giraffe may be ten feet long. Others may be very short. Wiki User

What would happen without neurons and their support cells?

Everything we think and feel and do would be impossible without the work of neurons and their support cells, the glial cells called astrocytes (4) and oligodendrocytes (6). Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3).
