Complete answer: Neuron also known as a nerve cell is a cell that is the longest cell of animals which has the capability to get excited by electrical or chemical impulse.
Which cell is the longest 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.
Do you know which cell is the longest in all animals?
Answer Expert Verified
Nerve cell is longest cell in the body ,and in that, the longest never cell is Sciatic which runs from each side of the lower spine.
What is the longest nerve cell in animals?
The giant axon of the squid is the largest known nerve cell in the animal kingdom. They can be up to 1mm in diameter and almost a metre long.
Who is the smallest cell?
Answer: A cell is described as the smallest, basic unit of life in charge of all the processes of life. The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long. The RBC ‘s size also found roughly 5 micrometers.
What is the oldest cell in the human body?
The oldest cell in your body is probably in your brain — your cerebral cortex. Researchers think these cells are with you from birth (although some can regenerate, more on this later). The youngest cell in your body at any given time is probably a neutophil, which is a type of white blood cell.
Which animal cell is long and branched?
nerve cells are branched in animals like humans. An animal cell which has a branched structure is nerve cell also known as neuron.
Which cell stops dividing after birth?
Neurons/nerve cells are the structural and functional unit of the nervous system. They continue to divide for a very short window after childbirth and then stop dividing to ensure the constant neuron connections in brain cells which in turn determine the memory and other working processes of the brain.
What is the peculiarity of nerve cell?
Answer Expert Verified
The nerve cells are also known as neurons. They are peculiar because they are the main communication and information tool in a human, animal or organism. … Nerve cells are little computers in a body.
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. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across).
What animal has the most neurons?
The largest number of cortical neurons in non-primate mammals is found in the false killer whale with 10 500 million and the African elephant with 11 000 million, which is less than the number found in humans, despite the much larger brains of the former two.
How long is the longest axon in the human body?
The longest neuron in the human body has a single threadlike projection (the axon), a few micrometers in diameter, that reaches from the base of the spine to the foot, a distance of up to one meter.” For axon length of over a meter see Cavanagh (1984, PMID 6144984 p.
Is a virus a cell?
Because they can’t reproduce by themselves (without a host), viruses are not considered living. Nor do viruses have cells: they’re very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.
What is the biggest cell in the female human body?
The ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. The human ovum measures approximately 0.1 mm (0.0039 in) in diameter.
