Relationship and possible function of the nasal sacs and glands of the one-humped camel, camelus dromedarius.

The relationship between the lateral nasal gland and sacs of the maxillary recesses was investigated. The nasal sacs possess a well-defined aperture communicating with the nasal cavities. It was concluded that the sacs and not the body of the gland produce mucous secretions that moisten the inhaled dry air of the desert and may also act as reservoirs. A possible function of the body of the nasal gland is water economy by excretion of concentrated salts.
