Two basic types of acinar epithelial cells exist: Acini in the parotid glands are almost exclusively of the serous type, while those in the sublingual glands are predominantly mucous cells. In the submaxillary glands, it is common to observe acini composed of both serous and mucous epithelial cells. submaxillary (mandibular) glands-produce a mixed serous and mucous secretion. 2  sublingual glands-secrete a saliva that is predominantly mucous in character. 3  serous cells, which secrete a watery fluid, essentially devoid of mucus. 4  mucous cells, which produce a very mucus-rich secretion.
exploratory - serving in or intended for exploration or discovery; an exploratory operation; exploratory reconnaissance; digging an exploratory well in the Gulf of Mexico; exploratory talks between diplomats. explorative. nonexplorative, nonexploratory, unexplorative, unexploratory - not exploratory.
Exploratory factor analysis is a statistical technique that is used to reduce data to a smaller set of summary variables and to explore the underlining theoretical structure of the phenomena. It is used to identify the structure of the relationship between the variable and the respondent. Exploratory factor analysis can be performed by using the following two methods: R-type factor analysis: When factors are calculated from the correlation matrix, then it is called R-type factor analysis.
