Mokraćni mjehur i njegova funkcija je još uvijek problem za fiziologe. Mi ćemo spomenuti tri pojave koje cine funkciju mokracnog mjehura teže razumljivom. Mijenjanjem volumena mokraće u mokraćnom mjehuru unutarnji pritisak se vrlo malo mijenja ili se nikako ne mijenja. Glatki mišici mokraćnog mjehura imaju stalno tonus koji je različite prirode od tonusa drugih glatkomišićnih organa i poprečno prugaste muskulature. Autonomna inervacija mokraćnog mjehura nije recipročna kod raznih vrsta životinja, nego su obje vrste nerava simpatički i parasimpatički nervi, motorni nervi, tj. izazivaju kontrakciju izvjesnih dijelova muskulature. Parasimpaticka inervacija se ne može potpuno blokirati parasimpatikoliticima (atropin), niti simpatička — simpatikolitcima (Garry, 1957, Edge, 1955).
