. what nerve carries the message from your eyes to your brain?
1 Relay neurones carry messages from one part of the central nervous system to another. 2  Motor neurones carry signals from the central nervous system to an effector-a part of the body that produces the response to the signal. Nerves are cells called neurones, which make up our nervous system. Nerves are specialised cells-they carry messages from one part of the body to another, as tiny electrical signals. 1 Receptors are located in organs such as the ear, eye and skin. 2  Each organ has receptors sensitive to particular kinds of stimulus e.g. sound, movement, touch. 3  Relay neurones carry messages from one part of the central nervous system to another. Traumatic optic neuropathy can be caused by a direct injury to the optic nerve, or injuries near the nerve can cause damage from swelling, bleeding, or infections. Damage can happen with any injury to your head or eye socket such as: 1  Falls. 2  Car or bike accidents. 3  Sports injuries. Our senses detect changes in our environment and send messages to the brain to tell the body how to respond. Sensory neurons (nerve cells) carry information to our brain and motor neurons carry messages away from our brain and to our muscles. This communication between our brain and body is happening constantly. We are able to sense what is happening in our surroundings and do something in reaction to it. View image. The optic nerve connects your eyes to your brain. It carries the visual messages that you see to your brain. An injury to your optic nerve is called traumatic optic neuropathy. If your injury is severe, you may have permanent changes in your vision. Optic nerve: The optic nerve connects the eye to the brain. The optic nerve carries the impulses formed by the retina, the nerve layer that lines the back of the eye and senses light and creates impulses. These impulses are dispatched through the optic nerve to the brain, which interprets them as images. Using an ophthalmoscope, the head of the optic nerve can be easily seen. The lens is the transparent structure inside the eye that focuses light rays onto the retina. The retina is, as mentioned, the nerve layer that lines the back of the eye, senses light and creates impulses that go through the optic nerve to the brain. In sum, the optic nerve is uniquely a part of both the eye and the brain. It is embryologically the brain's envoy to the eye and functionally the eye's envoy to the brain. Your nerves will tell your leg muscles to move. Nerve cells carry messages from one part of the body to another. There are three different types of neurones, each with a slightly different function. 1  Sensory neurones carry signals from sensory receptors to the spinal cord and brain. 2  Together, the spinal cord and brain make up the central nervous system.
