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?
Is the optic nerve a organ?
yes
What is the purpose of the optic nerve of a cheetah?
sensory nerve carry information from end organ (here retina)
Why eyes considered as most important organ of the body?
No it is a part of the optic nerve.
Is nerve an example of an organ system?
No, a nerve is one part of an organ system--the nervous system.
What nerve carries signals from the from the retina to the brain?
Occipital nerve. It is the second cranial nerve.
Is nerve cells an organ?
No, nerve cells are not organs. Nerve cells, also known as neurons, are the basic building blocks of the nervous system and are responsible for transmitting information throughout the body. The nervous system, which includes the brain, spinal cord, and nerves, is the organ system in which nerve cells are found.
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
