What neurons are there in the eye?
Specialized cells, called retinal ganglions, together with bipolar cells, amacrine cells, and horizontal cells, carry the visual information to the optic nerve (cranial nerve 2). This nerve then carries the information from the retina at the back of the eye to the visual cortex in the occipital lobe (back of the head).

How does the skin communicate sensory information to the brain?
The skin communicates sensory information to the brain through specialized nerve endings called sensory receptors. These receptors detect various stimuli such as touch, temperature, and pain, and send signals through nerve fibers to the brain for processing and interpretation.
How do hair follicle nerve endings respond to external stimuli?
Hair follicle nerve endings respond to external stimuli by detecting changes in temperature, pressure, and movement. When stimulated, these nerve endings send signals to the brain, which interprets the sensation as touch, pain, or other sensory information.
What structures from the gustatory pathway?
Primary somasthetic afferent neurons are found taste buds in the anterior 2/3rds of the tongue. Those fibers are carried towards the midbrain by the Chorda Tympani nerve (those are joint fibers from the lingual branch of the mandibular division of the Trigeminal nerve), which enters the tympanic cavity via the iter chorda posticus and exits thru the iter chorda anticus or the petrotympanic fissure. The nerve synapses with in the geniculate gangion of the VII cranial nerve. The secondary sensory neurons now travel through to the midbrain where they synaps with Nucleus tractus Solitarious. The tertiary fibers then go to parietal operculum of the parietal lobe (brodman area #43) the ultimate level of concious interperation of gustatory (taste) impressions.
Does your brain have nerve endings?
No, the brain itself does not have nerve endings. Nerve endings are found in other parts of the body, such as the skin, that send signals to the brain.
Which specific lobe does vestibulocochlear nerve send information to?
temporal lobe
What nerve that contains fibers that both send and receive messages is called?
A mixed nerve, such as the trigeminal nerve, contains both sensory and motor fibers that can send and receive messages. These nerves are responsible for carrying both sensory information from the body to the brain and motor commands from the brain to the muscles.
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
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.
The rods and cones send signal to the brain along a thick nerve called the?
Optical nerve
What part of the ear send the message to the brain?
The vestibulocochlear nerve, or 8th cranial nerve.
