pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
The parasympathetic division of the autonomic nervous system is responsible for mediating the reflex release of saliva. Stimulation of the parasympathetic nerves activates saliva production by the salivary glands.
The sensation of warm water on your hands can activate the body's parasympathetic nervous system, leading to relaxation and a sense of comfort. This can potentially stimulate the bladder and trigger the urge to urinate as a reflex response.

The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
Salivation is primarily controlled by the autonomic nervous system, specifically the parasympathetic nervous system. When stimulated, the parasympathetic nervous system activates salivary glands to produce saliva, which helps with digestion and swallowing. Additionally, sensory input such as the smell or taste of food can also trigger the salivary reflex.
The micturition reflex is the body's automatic response to the feeling of a full bladder and typically manifests as the urge to urinate. This sensation can vary in intensity from mild discomfort to strong urgency depending on the individual and the level of bladder fullness.
Micturition reflex is the neurological pathways involved in urination. When your bladder fills, the detrusor muscles expand and proprioceptors within the walls of the muscle activate. It sends signals (afferent nerves) that go to your medulla and also to the parasympathetic system in the sacral spinal cord. The signal to the parasympathetic system elicits the response to urinate by relaxing the inner external sphincter and constricting the detrusor muscles. However, first your upper brain is consulted and decides whether it is appropriate to go or not. If your brain allows, it will elicit the response by inhibiting the sympathetic nervous system and inhibiting the somatic nervous system. The somatic nervous system controls the external sphincter and by inhibiting it, you are relaxing it. The external sphincter is much more powerful than the internal sphincter. If your brain says no, it will activate the sympathetic nervous system (which relaxes the muscle walls and constricts inner sphincter) and your somatic control continues to constrict the external sphincter.
The autonomic nervous system consists of the sympathetic nervous system, which prepares the body for fight or flight responses, and the parasympathetic nervous system, which promotes rest and digestion.
The autonomic nervous system (ANS) is divided into the sympathetic and parasympathetic divisions. The sympathetic division is responsible for the "fight or flight" response, increasing heart rate and pupil dilation. The parasympathetic division is involved in rest and digest functions, promoting activities like digestion and lowering heart rate.
The effectors of the salivary reflex are the salivary glands, which produce and release saliva in response to stimuli such as the sight, smell, or taste of food. The parasympathetic nervous system is primarily responsible for stimulating the salivary glands during this reflex.
