What system are eyes a part of?
The ocular system consists of the eye and its central visual system . Light images from the outside pass through the central visual system (cornea, the lens, and fluids) to land upon the retina. The retina then generates the signals passed by the optic nerve to the brain and interpreted as vision.
How is the eye related to the nervous system?
When focused light is projected onto the retina, it stimulates the rods and cones. The retina then sends nerve signals are sent through the back of the eye to the optic nerve. The optic nerve carries these signals to the brain, which interprets them as visual images.
Is the skin part of the nervous system?
The skin, which is part of the integumentary system, plays an important role in the somatic nervous system because it contains a range of nerve endings that react to heat and cold, touch, pressure, vibration, and tissue injury.
What is the importance of eyes?

What is the relationship between the eyes and ears and the nervous system?
The Cranial Nervous System nerves connect the brain to the eyes, mouth, ears and other parts of the head. The Autonomic Nervous System nerves connect the central nervous system to the lungs, heart, stomach, intestines, bladder and sex organs. The branch of medicine that studies the nervous system is called neurology.
What parts of the nervous system are involved in eye movement?
The four cranial nerves involved in vision and movement of the eyes are the optic (II) nerve, oculomotor (III) nerve, trochlear (IV) nerve and the abducen (VI) nerve. The optic nerve is the sensory nerve for vision.
Why is it important to take care of eyes?
Your eyesight is one of your most important senses: 80% of what we perceive comes through our sense of sight. By protecting your eyes, you will reduce the odds of blindness and vision loss while also staying on top of any developing eye diseases such as cataracts and glaucoma.
