The retina is the part of the eye that contains light receptors.

What is an eye part of which starts with sn?
Nervous System
What organ system allows you to see?
The eye is a part of the nervous sytem, which is essentially a network of neurons that coordinate actions and transmits signals throughout the body. There are two parts to the nervous system: central and peripheral. The eye is a part of the central nervous system, which also contains the brain and spinal cord.
How does sympathetic nervous system affect the iris?
The sympathetic nervous system is one of three major parts of the autonomic system. The autonomic nervous system (ANS) is the part of the nervous system that controls most of the things we don't do voluntarily. Things such as heart rate, respiratory rate, sexual arousal and tone of the muscle inside your eye (the iris). The sympathetic part of the ANS is often considered to promote a "fight or flight response" while the parasympathetic part does the opposite ("rest and digest"). If we think about a dangerous situation where you want to have a "fight or flight response", you generally want to have more light entering your eyes so that you have a heightened visual sense. This is accomplished when your sympathetic nervous system activates the radial muscles of your iris. In contrast, your constricter muscles are relaxed. This leads to dilated pupils forming part of the sympathetic response.
What parts of the central and peripheral nervous system have to be functioning for the senses of hearing and vision?
For the sense of hearing, the central nervous system (specifically the auditory cortex in the brain) and the peripheral nervous system (including the auditory nerve and cochlea in the ear) must be functioning. For vision, the central nervous system (particularly the visual cortex) and the peripheral nervous system (including the optic nerve and retina in the eye) are necessary for proper function.
Large bundles of axons and dendrites visible to the unaided eye are?
Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
The eye is considered part of what system?
the eye is part of the nervous system, but more specifically, the peripheral nervous system.
Can you consider eyes to be part of the nervous system?
Well that depends. If you are referring to the eye on a whole, then the answer is no, the eye is considered part of the optical system. But if you mean "is any part of the eye consider to be part of the nervous system?", then the answer is yes, the optical nerve situated at the back of the retina, is part of the nervous system
