Your photosensitive eyes are an extension of part of the brain surface. From clever experiments it is known that all of the surface of the brain is photo sensitive.
Even some primitive organisms that do not yet have a brain, nevertheless have light sensitive receptors that are used to direct actions.
What else can I help you with?
What nerve carries signals from the from the retina to the brain?
Occipital nerve. It is the second cranial nerve.
What is the point where the optic nerve enters the eyeball?
Point where optic nerve enters eyeball is the optic disc.
Which part of the nervous system is damaged in cases of Glaucoma?
Optic nerve
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What is similar between the optic nerve and the auditory nerve?
The optic nerve and the auditory nerve are both crucial components of the sensory nervous system, responsible for transmitting sensory information to the brain. Each nerve carries signals from specialized sensory receptors—photoreceptors in the eyes for the optic nerve and hair cells in the cochlea for the auditory nerve. Both nerves play essential roles in enabling perception, with the optic nerve facilitating vision and the auditory nerve facilitating hearing. Additionally, they are both part of the central nervous system pathways that process and interpret sensory stimuli.
Where does the optic nerve leave the eye?
The optic nerve exits the retina at the optic disc, otherwise known as the "blind spot".
Which nerve belongs to the peripheral nervous system A. Sciatic nerve B. Vagus nerve C. Optic nerve D. Trigeminal nerve?
sciatic
What is another name for the optic nerve head?
Another name for the optic nerve head is the optic disc.
What nerve is responsible for visual signals to the brain?
optic nerve
What can the optic nerve be identified with?
The optic nerve can be identified with the sense of sight.
What is the junction of the retina and optic nerve?
The junction of the retina and optic nerve is called the optic disc or optic nerve head. This is where the optic nerve exits the eye and carries visual information from the retina to the brain. The optic disc is also known as the blind spot because it lacks photoreceptor cells and cannot detect light.
Does the optic nerve pass through the foramen ovale?
The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
