How many percent of the optic nerve fibers are responsible for light reflex?
Approximately 20% of the optic nerve fibers are responsible for the light reflex. These fibers are involved in transmitting the signal from the retina to the brain to regulate the constriction of the pupil in response to changes in light intensity.
Is the optic nerve a single nerve or a bunch of nerves connected?
It is a bundle of neurons, all flowing from the same general source (the eye) to the optic chiasm.
What does carry the impression on retina to brain?
The optic nerve.
What do you call collection of nerve fibers in the brain longitudinal in form?
The collection of nerve fibers in the brain that are longitudinal in form is called a "fasciculus." Fasciculi are bundles of nerve fibers that travel together and share a common function or destination within the brain.
The brain linked to the eyes by?
The brain is connected to the eyes by the optic nerve. This nerve carries visual information from the retina of the eye to the brain, where it is processed to create our sense of vision.
What is the optics?
It is a bundle of nerve fibers that carry electrical impulses to the brain from the retina.
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.
The visual pathway to the occipital lobe of the brain consists most simply of a chain of five neurons beginning with the photoreceptor cell of the retina name them and note their location in the pat?
Photoreceptor cells in the retina. Bipolar cells in the retina. Ganglion cells in the retina. Optic nerve fibers in the optic nerve. Lateral geniculate nucleus in the thalamus. Optic radiation fibers in the brain to the primary visual cortex in the occipital lobe.
How does the retina send messages to your brain to tell what your seeing?
retina is connected to the nerve and the nerve sends the messages or images to the brain and the brain processes the images
How many percent of the optic nerve fibers are responsible for light reflex?
Approximately 20% of the optic nerve fibers are responsible for the light reflex. These fibers are involved in transmitting the signal from the retina to the brain to regulate the constriction of the pupil in response to changes in light intensity.
Is your optic nerve atached to your retina?
yes it is, and the optic nerve is attached to your brain.
Is the optic nerve a single nerve or a bunch of nerves connected?
It is a bundle of neurons, all flowing from the same general source (the eye) to the optic chiasm.
What nerve carries signals from the from the retina to the brain?
Occipital nerve. It is the second cranial nerve.
Impulses leave the eye by way of?
Impulses leave the eye by way of the optic nerve, which transmits visual information from the retina to the brain for processing. The optic nerve is a bundle of nerve fibers that carries these signals to the brain, allowing us to perceive and interpret the images we see.
What is the optic nerve?
I don't know but you are getting on my nerves! Well I do know. The optic nerve is the second cranial nerve and carries information from the eyes into the brain. It does not have any control over the movement of the eyes as this comes from other nerves it only takes special sensory information on the images that the retina is receiving back to the brain to be processed. The optic nerve contains approximately 1.2 million neurons.
What does carry the impression on retina to brain?
The optic nerve.
How do you spell retnia?
retina I am assuming you mean retina as in the nerve that connects your eyeball to your brain.
