The pupillary light reflex is control by what autonomic nervous system?
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
What division of the autonomic nervous system mediates the reflex release of saliva?
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.
Why does hot water on your hands make you pee?
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.
What receptors are stimulated in the micturition reflex?
Stretch receptors in the bladder wall are stimulated during bladder filling, sending signals to the spinal cord. Parasympathetic nerve fibers release acetylcholine to contract the detrusor muscle and relax the internal urethral sphincter. Sympathetic fibers release norepinephrine to contract the external urethral sphincter, allowing for voluntary control.
What are the divisions of the ANS?
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.
What is another name for micturition reflex?
Urination erection?
What triggers the micturition reflex in the walls of the bladder?
stretch receptors
What is the micturition reflex?
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.
Name the division of autonomic nervous system responsible for pupillary light reflex?
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.
What does the micturition reflex feel like?
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.
What are the subsystems of the autonomic nervous system?
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.
Is the pupillary light reflex sympathetic?
No, the pupillary light reflex is mediated by the autonomic nervous system, specifically the parasympathetic nervous system. When light is detected by the retina, it triggers a reflex that causes the pupils to constrict, a response mediated by the parasympathetic nervous system.
