Bladder spinal reflex is the mechanism so you can
consciously void urine. There are receptors in the bladder that senses the
amount of urine collected. These are responsible for that ‘voiding urge’. The
higher the amount of urine collected, the greater the intensity of the signals.
Finally, when you get to the bathroom,
another set of nerves lets you consciously urinate so you can select which bathroom
stall is nice for peeing. Diabetes mellitus can damage nerves in the spinal
cord, including those involved in functioning of the bladder. Damage to the nerves
in the bladder spinal reflex arc is suspected if the patient suffers from
urinary retention – where the patient can consciously void urine but cannot
feel if the bladder is full.
I found the exercise on the internet and these were the options:
"-Help
-Pelh
-Elhp
<span>-Pleh"
The letter "p" would be fastest recognised by an English speaker in "Help". Letters are more recognisable when they are in a context that's known. If any of the other words was given to an English speaker to memorise, he would probably memorise the letter by letter, while with "help", he would be able to know straight way what letters were contained in it without having to make a conscious effort to memorise them one by one. Because of this, the letter "p", for an English speaker would be the fastest recognised in the word "help" rather then in other unknown word.</span>
