How does the sheep's cerebral cortex compare to the human cerebral cortex?
The depth of the fissure creating the cerebral hemisphere in a human brain is larger than that of a sheep. This is due to the fact that the human brain is larger and rounder compared to the elongated brain of the sheep.
Where are neurons located in the body?
In the head and spinal cord mostly all over but most of them are in your head.
What do sensory neurons carry impulses from the CNS?
The sensory (or afferent) neuron carries messages to the brain and then the motor (or efferent) neuron carries the reaction message from the brain to the gland or muscle being effected in response. :)
What are some nerve cell What are facts?
the last loser that said i don't know is dumbthe answer isThere are more nerve cells in the human brain than there are stars in the Milky Way.it sends orders to the brain and all over the body and the body responds with the action.
Describe the means by which individuals who survive a stroke regain at least part of their lost abilities?
It all depends on where the stroke is located and how extensive the area the stroke affects. The brain, which is were most strokes occur, does not replace dead neurons. Sometimes if the stroke is not too extensive other parts of the brain can take over. Physical therapy can sometimes help find those other parts of the brain.
How many neurons are in your brain?
About 1,000,000,000. Or one billion.100 billion neuron cells re in the brainThere are approximately 100 billion neurons in the human brain.
How many cells are in the brain?
There is about 160,000,000,000 cells in human brain. Half of the number are neurons, which are rensponsible for all the "thinking" functions. The other half are "glial cells", which help neurons with their activity.
What has the neuron got to do with the brain?
So, neurons are in the blood vessels. blood vessels originate from the brain. So, the main source of the cardiovascular system starts with the brain. Then arteries and veins spread all over the human body. and neurons lie within the vessels.
How many neurons can be found in the brain?
its over 9000!

How much does the human brain remember?
over 100000
How many cells in the human brain?
There are over 400,094,800 cells in the human brain, while the entire body has about 50 to 75 trillion cells.
How do you feel texture with your fingers?
There are sensory neurons on your fingers and all over your body, which then goes to your interneuron in your spinal cord, then it sends a message to your brain.
Which hemisphere controls the right side of the body?
Neurons cross from the right side to the left, as do neurons cross from the left to the right, meaning your right side of your brain controls your left, and your left controls your right side.
How many brain cells are human born with?
"you are born with over 16trillion brain cells."Another answer that appears to be wildly off the mark. Amazing what a huge variation I'm finding on this one.The consensus seems to be around the 100 billion mark:Glencoe Health 2nd Edition. Mission Hills: Glencoe Inc., 1989: 252."Weighing around three pounds (1.35kg), the brain contains nearly 100 billion cells."100 billionWorld Book 2001.

Salem Press, 1998: 221."It has been estimated that the adult brain has around one hundred billion neurons and an even larger number of glial cells."100 billionThe Science Times Book of the brain.

New York: Scientific American, 1999: 3."An adult human brain has more than 100 billion neurons"> 100 billion
How many neutrons are in a brain?
Over 400,094,800 cells is the answer listed here, which appears to be completely incorrect.A quick Google search found a consensus around the 100,000,000,000 mark. Here are the sources.Glencoe Health 2nd Edition. Mission Hills: Glencoe Inc., 1989: 252."Weighing around three pounds (1.35kg), the brain contains nearly 100 billion cells."100 billionWorld Book 2001.

New York: Scientific American, 1999: 3."An adult human brain has more than 100 billion neurons"> 100 billionPlease note that "the answer listed here" - over 400,094,800 - refers to the number of cells in the human brain. The 100 billion figure, mentioned repeatedly in the sources quoted above, refers to neurons or nerve cells, which are only one kind of brain cell. As indicated by the 3rd cited source, neurons are actually thought to comprise less - far less, according to most authorities - than 50% of the total. (Glial cells are the most numerous.) So 400,094,800, while an improbably specific number, could well be close to the mark.the brain has about 1 billion cells
