What is a group of axons bundled together called?
a nerve is bundled together by neuron fibers. The CELL BODY OF A NERVE or neuron is surrounded by satellite cells.
What does cytoplasm do in inside nerve cells?
the cytoplasm is the part connected to nerve cell, nerve cell uses the cytoplasm to send neurons across
What is the function of axon terminal?
the primary function is to send nerve signals to the various parts of the body
What is the function of the nerve cells?
The functions of the nerve cells is to carry messages around our body. To adapt to their job, they are very long and are branched at each end.Nerve cells receive, carry, and pass electrical impulses.Neurons (or nerve cells) are the smallest unit of the nervous system which send signals to the rest of the body to perform what ever function the brain wants it to; such as telling the heart to beat.
Where will the brain send nerve impulses or hormones if the blood flowing through it has too much water?
No
Which specific lobe does vestibulocochlear nerve send information to?
temporal lobe
What is the name of the nerve that takes information about balance and hearing to the brain?
The vestibular part of the vestibulocochlear nerve will send information about the equilibrium and balance.
What receives information from other nerve cells and then they send it to other nerve cells and attach to another cell body?
dendrites
Human Nerve Cells?
Nerve cells specialized on transmitting messages from one part of the body to another. Motor neurons send information away from the central nervous system (CNS). Sensory neurons send information toward the CNS. Inter-neurons send information between motor and sensory neurons.
Rods and cones inside the eyeball send visual signals to what lobe of the brain?
Occipital lobe
How does the optic nerve work?
The optic nerve is a group of nerve fibers that function to provide vision. The optical never works by transferring electrical impulses to the brain from a part of the eyes known as the retina.
Why do only some people sneeze when they take a quick look at the sun?
No one is actually 100% sure but the most likely explanation is as follows.The Photic Sneeze Reflex (sounds like an 80's one hit wonder band) as it's been named, has been suggested to be a result of inappropriate "cross talk" between two of the cranial nerves within the skull.The first, the optic nerve, carrys "sight" information from the eye, where the retina turns light signals into electrical signals*, to the brain, where these signals are decoded and used to generate vision.The second, the trigeminal nerve, mediates the sneezing reflex, receiving information about irritants in the nasal passages and relaying the appropriate signals for the sequence of rhythmic muscular contractions in the airways which generate/constitute a sneeze.The principle is the same as squeezing toothpaste out of a tube by repeatedly crushing the tube just behind the paste, just very very quickly: sneezes can force air out at over 100mph.Nice to know, but what does this have to do with the sun?Well, nerves work, by sending electrical signals. If two nerves are close enough, exciting one can unintentionally stimulate the other.In this case it is thought that, in some people, the trigeminal nerve is occasionally mistakenly "excited" by the nearby optic nerve, the nerve which transmits "sight" information to the brain.You can probably see where this is going now..The sun, even 93 million miles away, is incredibly powerful as a light source. When looking directly at the sun we send very strong electrical signals** down the optic nerve to the brain. Along the way, it is thought, these messages also excite the trigeminal nerve which responds by generating a sneeze.So there it is, the Optic nerve, responding to sudden huge light signals, sends messages to the brain but also fools the trigeminal nerve into thinking you need to sneeze.
Nerve cells send out signals?
Yes they do send out signals
What is the function of cells in the human body?
Nerve cells specialized on transmitting messages from one part of the body to another. Motor neurons send information away from the central nervous system (CNS). Sensory neurons send information toward the CNS. Inter-neurons send information between motor and sensory neurons.
What part of the ear send messages to the brain?
The vestibulocochlear nerve, or 8th cranial nerve.
What part of the ear send the message to the brain?
The vestibulocochlear nerve, or 8th cranial nerve.
What nerve that contains fibers that both send and receive messages is called?
Sensory Nerve
