No evidence is available regarding changes in blood pressure directly due to the neurogenic bladder. However, a rise in blood pressure can occur indirectly if the cause is Spinal cord injury that also affect the kidneys. Kidneys would result in increase water and salt absorption causing indirect increase in blood pressure.
Yes, reflex neurogenic bladder can lead to an increase in blood pressure due to the autonomic dysregulation that is often seen in neurological conditions affecting bladder function. This dysregulation can cause fluctuations in sympathetic nervous system activity, leading to changes in blood pressure.

What is the sacral reflex arc?
The sacral reflex arc refers to the neural pathway that controls involuntary responses in the sacral region of the spinal cord. It involves sensory neurons detecting stimuli and transmitting signals to the spinal cord, which then sends motor signals back to the muscles or glands in that region to produce a reflex action. This reflex arc helps regulate functions such as bowel and bladder control.
What is the duodenocolic reflex?
The duodenocolic reflex is a gastrocolic reflex that occurs when food enters the duodenum, triggering a reflex response in the colon to promote defecation. This reflex helps facilitate the movement of waste through the digestive system by increasing colonic motility.
Examples of visceral reflexes?
Examples of visceral reflexes include the pupillary light reflex, which causes the pupil to constrict in response to bright light, and the cough reflex, which helps to clear the airway when irritants are detected. Other examples include the gag reflex, which protects the airway from foreign objects, and the peristaltic reflex, which moves food through the digestive system.
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.
Is the micturition reflex center is located in the pons?
No, the micturition reflex center is located in the sacral region of the spinal cord, specifically at the level of the S2 to S4 segments. This center regulates the process of urination, including the contraction of the bladder and relaxation of the internal urethral sphincter.
What is atrial reflex?
Atrial reflex is also known as the Bainbridge reflex which is an increase in heart rate due to central venous pressure of the heart. The atrial reflex controls the heart rate more so in dogs than in humans or other primates.
What triggers the micturition reflex in the walls of the bladder?
stretch receptors
What is emptying the bladder controlled by?
The micturition reflex tells you when you need to empty your bladder. This happens on average four to eight times a day. The reflex is controlled by your central nervous system. When your bladder is about half full, the stretch receptors in the walls of your bladder become active and send signals along your pelvic nerves to your spinal cord. A reflex signal is sent back to your bladder, which makes the detrusor muscle in the bladder wall contract. The contraction increases the pressure in your bladder, and this is what makes you want to pass urine. Because the external sphincter is under voluntary control, you don't urinate until you decide to relax this muscle. simple answer would be this; Sphincter muscle that surrounds the urethra.
How calculate bladder capacity of a child?
You can't. Just use general statistics for their age and gender. Bladder capacity also has little to do with mitrical reflex.
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.
How stimulate the sacral reflex arc?
To stimulate the sacral reflex arc, you can apply pressure to the S2 to S4 dermatomes in the sacral region, typically done by gently tapping or stroking the perineal area. This can promote the reflexive contraction of the bladder and relaxation of the external urethral sphincter, triggering a reflexive voiding response.
Does epinephrine raise or lower blood pressure?
A definite NO. Phenylephrine causes marked increase in systolic, diastolic, and pulmonary pressures, as well as reflex bradycardia.
What is the sacral reflex arc?
The sacral reflex arc refers to the neural pathway that controls involuntary responses in the sacral region of the spinal cord. It involves sensory neurons detecting stimuli and transmitting signals to the spinal cord, which then sends motor signals back to the muscles or glands in that region to produce a reflex action. This reflex arc helps regulate functions such as bowel and bladder control.
What is a bass reflex?
A bass reflex is a form of loudspeaker enclosure which uses sound from the rear side of the diaphragm to increase the efficiency of the system at low frequencies.
What is the duodenocolic reflex?
The duodenocolic reflex is a gastrocolic reflex that occurs when food enters the duodenum, triggering a reflex response in the colon to promote defecation. This reflex helps facilitate the movement of waste through the digestive system by increasing colonic motility.
What receptors are stimulated during urination?
Nerve receptors are stimulated during urination. This stimulation occurs when the walls of the bladder contract and the urination reflex is automatically activated.
The carotid sinus reflex protects the blood supply to the brain whereas the aortic reflex is more concerned with maintaining adequate blood pressure in the systemic circuit as a whole?
True
