Most cells are microscopic and can be seen only with microscopes. However, some nerve cells can be in excess of one meter long. The cells are adapted to carry information to and from all parts of the body. See the related link for a brief description of the cells and some diagrams.
the length of a typical DNA molecule is roughly 1.6 mm
- Stretched out the length of DNA in a human cell is approximately 3.6 meters
Yes some of the nerve cells that leave the spine and run down the leg can reach that length (the sciatic nerves).
Some neurons (nerve cells) can be longer than a meter. The longest muscle is the sartorius but it is only about a half a meter.
It is Bone Marrow (long Bone)
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.
In the human body we have lots of cells. Red blood cell's-this has a dip on it to carry oxygen around the body. The cell is blood White blood cell's-helps us when were sick. It fights the germs. Nerve cell's-is long and thin and it looks like an electric shock. It carries out reactions Sperm cell's-are found in male and helps make reproduction egg cell-found in a female and helps to make reproduction
Axon
An axon is the long extension of a nerve cell body. The dendrites are the short branches.
While axons of the neuron are often mere micrometres thick, they can be up to a meter long (and longer in adults). This makes the neuron the longest cell in the body.
The longest cells are neurons (nerve cells) with a length of 90cm-100cm linking the central nervous system (brain and spinal cord) to other parts of the body.
The parts of a generic neuron are:- soma - cell body axon - upto 1 meter long dendrite - many
This is very TRUE.The only human cell capable of this feat is the neuron.Neurons range from millimeters to longer than a meter!Biology is awesome.
While axons of the neuron are often mere micrometres thick, they can be up to a meter long (and longer in adults). This makes the neuron the longest cell in the body.
If you take all the DNA from a single human cell and stretch it into a single connected line, the DNA polymer will be about 1 meter long (1.02 m to be more accurate).
It is Bone Marrow (long Bone)
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 nerve cell (particularly those forming the axions in the spine and from the spine to the foot).
There are a number of contenders for the position of smallest cell in the human body. The head of the sperm is on average 5 to 6 micro meters. The flagellum is up to 50 micrometers long. Also some says Granule Cell of the Cerebellum is the smallest cell of the human body it is approximately 4um to 4.5um in size. The size of the RBC also found as around 5 micrometers. In terms of volume most of the scientists suggest that sperm is the smallest cell.
Cells come in many sizes. They all aren't the same
The smallest cell in the human body is the male sperm. The cell head is about 3 µm by 5 µm and the tail (flagellum) is about 41 µm long (µm = micrometers). Oddly enough, the largest cell in the human body is the female egg (ovum), which is about the size of the period at the end of this sentence.
