i would think its the iris,due to studies i have done on the topic
The anterior visual pathway refers to the pathway that visual information takes from the eyes to the visual cortex in the brain. It includes the optic nerves, optic chiasm, optic tracts, and lateral geniculate nucleus. This pathway is responsible for transmitting visual signals from the retina to the brain for processing and interpretation.
The pathway that the nerve impulse takes from your foot to your leg is called the sensory pathway. This pathway includes sensory neurons that carry signals from the foot to the spinal cord and then to the brain, where the sensation of pain is perceived and a motor response is initiated to move away from the tack.
The common catabolic pathway primarily takes place in the cytoplasm of cells. This pathway involves the breakdown of larger molecules into smaller units to release energy for cellular activities. The final products of this process can then enter other metabolic pathways to generate ATP.
During dark adaptation, the eyes adjust to low light conditions by increasing the sensitivity of the rod cells in the retina. This process allows for better detection of dim light by the eyes over time. It usually takes around 20-30 minutes for full dark adaptation to occur.
It takes place in the cristae, which are found on the matrix of the mitochondrion.
The pathway of light is light through the eye to the cornea. This is the path that light takes when entering the eye.

When light enters the eye, it passes through the cornea, then the lens, and ultimately reaches the retina at the back of the eye. Here, light triggers a chemical reaction in the cells of the retina called photoreceptors, specifically in rods and cones, which convert the light into electrical impulses that are then transmitted to the brain via the optic nerve.
Optic
Rods are a part of the eye that takes in low light. Cones are located in the retina and they are responsible for seeing in color. All mammals have rods and cones in their eyes.
Light from the sun reflects off the fish in the pond and travels through the air before entering your eye. The light passes through the cornea and lens, which focus the image onto the retina at the back of your eye. Photoreceptor cells in the retina convert the light into electrical signals, which are then sent to the brain, allowing you to perceive the fish. This entire process happens almost instantaneously, enabling you to see the fish clearly.
Intense light, such as from a flashbulb or uncovered light bulb, can stimulate the retina (the light-sensitive tissue at the back of the eye) to its maximum response. When this occurs, it takes awhile for the retina to "recover." For a short time you are not able to see well, or you may see spots or a dark afterimage.
The coronary pathway takes blood to the heart.Related Information:Coronary arteries surround the heart and provided the muscles of the heart with blood.
RETINA
Vision takes place in the eye's retina, where light is converted into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are processed and interpreted to form visual perceptions.
