They are located in the back of the eye, the retina. But you should have asked in which direction do they "look"? They aren't oriented towards the nose, but rather towards the back of the head! We see reflected light.

Both the nervous system and the endocrine system send messages to the brain
the nervous system consists of neurons. these neurons receive and transfer messages and help the nervous system to interact with other systems in our body. also the body has receptors, effectors, sensor and motor nerves which helpin the process of interaction.
Your body won't react to it which causes your body not to receive the message from the Nervous and Endocrine system. :)
The nervous system can affect only nearby cells. APEX
In your ears :)
Sensory receptors are a type of sensory nerve. The sensory receptors that are specialized to respond to light energy are called stimuli.

The brain sends them a message.
Sensory receptors gather information that is further processed by your brain. They tell your brain when it is getting cold, warm, wet, dry etc. Sensory receptors also tell your body when you are in danger. If you cut yourself, burn yourself, any damage to the body, and they will respond accordingly to prevent further damage.
The Nervous System
Thermoreceptors in the nerve cells of the mouth respond to temperature of objects. When these receptors are activated, ion channels are opened and action potentials are sent to the central nervous system. Cool objects/food activates these thermoreceptors. However, if something that is too cold enters the mouth, nociceptors will be activated. These receptors register pain and inform the central nervous system that the object is harmful.
The nervous system allows the body to send and receive messages and respond to the world around it.
