Tears lubricate your eyes. Dry eyes hurt especially when you blink. They also help to clean the gunk that you get in your eyes out.
Describe the pathway connecting photoreceptors of the eyes to the pineal gland?
The photo receptors in the eyes are not connected to the pineal gland. They are connected through the optic nerve (Cranial Nerve II) which goes through the brain stem and then into the occipital lobes of the cerebral cortex, also called the visual cortex. The pineal gland is in the area of the brain called the diencephalon and lies just anterior of the occipital lobes and so has indirect association with the cranial nerves that bring in impulses from the stimulation of the photo receptors to light. The information that the pineal gland gets about the amount of daylight, or broad spectrum light, that enters the eyes then allows it to set the day/night clock of the brain with the help of the hypothalamus.
How do the eye see?
The eyes "don't" see colour. The "brain" sees colour, the "eyes" are just "lenses", hun. k. the eyes have two types of nerve cells. rhods and cones. Rhods help see in dim light and cones help in identifing colors and help see in bright light. these 2 cells are called photoreceptor cells. they carry this info from the eye through the optic nerve to the brain. the answer to your question, cones are nerve cells in the eye that help distinguish colors. :)
Can surgery restore your sense of smell after an accident?
It depends of the type of damage that occurred during the accident. If your Olfactory nerve; Cranial Nerve I was damaged, then there is probably nothing that can be done. If there is no damage, just pressure on the nerve, then surgery may be able to help. Your best course of action it to talk to your doctor.
When is Cranial ultrasonography used on adults?
Cranial ultrasonography is also performed on adults during brain surgery to help identify the location of brain tumors
Does milk help stop your eyes from burning?
YES! I'm a swimmer and if you fill goggles with milk (the more fatty the milk the better) and hold it to your eyes it is instant relief. The fat molecules in the milk attach to the nerve endings in your eyes and stop the pain.
Why do you see things?
You see things when light reaches your eyes. Light enters through the pupils of your eyes and goes through the lens, which help form the image, to reach the retina, which transmits the picture to your brain through the optic nerve.
Do some people blink more than others?
Well, first their eyes might need to blink more so they don't get dry, or it could be Tourette's Syndrome. They often will shrug too often, get tics, and cough too often. If you are having any of these symptoms you may want to get this checked out. Hope i could help
How do horses keep the sand out of their eyes?
They have long eyelashes so those definitely help, but I think when it's sandy and your riding a horse if it is a stubborn horse it'll stop, or it will just blink a lot and make sounds and movements showing it's discomfort. If you are not riding the horse and there is sand coming towards its eyes it will probably close its eyes.
Why do frogs close their eyes when eating or feeding?
Most predators close their eyes when they grab prey. This is to protect the eyes. If an insect or other animal hit a frog's eyes, it could injure them. You can see other predators like sharks do the same thing. According to exploratorium.edu, "As a frog swallows its prey, the eyes sink through openings in the skull and help force the food down the throat. This is why frogs seem to blink as they eat".
