What senses are affected by the cranial and facial bones that protect and support the sense organs?
Cranial and facial bones affect the following senses: senses of vision, taste, smell, hearing and balance. Protection of the brain is done by cranial while facial forms the mechanical framework of the face.
What is the eyes main functions?
To see. Vision is the main function.
What function do you lose if you damage the temporal lobe?
Sense of smell and sound, speech, vision and memory.
Which insects rely on binocular vision?
Some insects that rely on binocular vision include the Praying Mantis and the Dragonflies. You can learn more about these insects online at the Wikipedia.
Chemical senses include vision and hearing?
No, they do not. The sense of taste is an example of a chemical sense.
Pure sensory cranial nerve?
Cranial nerves are primarily sensory. These nerves are directly between the brain and the brainstem and are responsible for smell, vision, eye movement, facial sensation, and the tongue movement.
How many nerves are in your eyes?
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.
What are the innervation of the eye?
Cranial nerve #2 - optic nerve - special sensory for vision Cranial nerve #3 - occulomotor nerve - motor for extraoccular muscles & parasympathetic to ciliary ganglion Cranial nerve #4 - trochlear nerve - motor for extraoccular muscle (superior oblique) Cranial nerve #6 - abduscens nerve - motor for extraoccular muscle (lateral rectus)
What cranial nerve is affected when you have parkinson's disease?
Parkinson's disease affects some of the functions for which cranial nerves are responsible, for example, by creating disturbances of vision and smell, but scientists are not certain whether this effect involves damage to the cranial nerves or to the areas within the brain that interpret sensory signals. Parkinson's symptoms such as difficulty in moving the eyes or swallowing relate to neuromuscular disruptions that take place in the basal ganglia and affect neuron communication to the muscles, rather than to damage that involves the cranial nerves that also have functions related to the muscles that move the eyes, tongue, and face. The route of transit remains intact although the signals traveling to it are distorted.
What cranial nerve deals with vision?
vestibulocochlear nerve
What contains neurons for vision?
nerves do that
Which carnial nerves are purely sensory?
Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
What is the the first pair of the cranial nerve?
I- Olefactory (sensory): smell. II- Optic (sensory): vision.
Do people with dark eyes have better peripheral vision than people with light eyes?
The layer of nervous cells sensitive to light as 2 most important cells. Roods and cones. The first are mostly in the peripheral parts of the retina and so gives the peripheral vision. They create a nervous stimulation when they are affected by a small quantity of light. The signal of a lot of rod are sum in only one nerves that goes to the brain and it became strong enough, and this is that motivation for the dimension of a "pixel" is bigger in this part of the peripheral vision. So the peripheral vision is more important in the night vision of animals, for the vision of the movement, but not for read. The central part is the part of the 3 types of cones, sensitive to 3 different electromagnetic radiation, cyan, magenta and yellow, that in combination are all the colours. And in the central part we can recognize how different points very close.

When nerves behind the eye fail what happens?
You most likely loose your vision
What is function of objectives?
It is just your vision or your goals, for me that is the function of objectives.
