ResumoThe nasal salt gland of the sea gull has been shown to elaborate a concentrated NaCl secretion in response to hypertonic sodium infusion. In order to more precisely define the secretory stimulus, gulls were expanded with hypotonic dextran solutions, infused with hypotonic sodium chloride solutions, and hypertonic sucrose and mannitol solutions. Secretion occurred in response to all hypertonic solutions but not to hypotonic sodium solutions nor to hypotonic volume expansion. It is concluded that nasal salt secretion is induced through osmoreception.
