Experience of Urination

The need to urinate is experienced as an uncomfortable, full feeling. It is highly correlated with the fullness of the bladder. In many males the feeling of the need to urinate can be sensed at the base of the penis as well as the bladder, even though the neural activity associated with a full bladder comes from the bladder itself, and can be felt there as well. In females the need to urinate is felt in the lower abdomen region when the bladder is full. When the bladder becomes too full, the sphincter muscles will involuntarily relax, allowing urine to pass from the bladder. Release of urine is experienced as a lessening of the discomfort.

Famous quotes containing the words experience of and/or experience:

    Whoever has had the experience of the moral sentiment cannot choose but believe in unlimited power. Each pulse from that heart is an oath from the Most High. I know not what the word sublime means, if it be not the intimations, in this infant, of a terrific force.
    Ralph Waldo Emerson (1803–1882)

    ... no other railroad station in the world manages so mysteriously to cloak with compassion the anguish of departure and the dubious ecstasies of return and arrival. Any waiting room in the world is filled with all this, and I have sat in many of them and accepted it, and I know from deliberate acquaintance that the whole human experience is more bearable at the Gare de Lyon in Paris than anywhere else.
    M.F.K. Fisher (1908–1992)
