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.

An exploratory laparotomy (ex-lap) is the standard of care in various blunt and penetrating trauma situations in which there may be multiple life-threatening injuries, and in many diagnostic situations in which the operation is undertaken in search of a unifying cause for multiple signs and symptoms of disease.he trauma ex-lap is the most comprehensive ex-lap, usually undertaken after evidence of internal bleeding (a positive FAST, DPL, or other overwhelming evidence for internal hemorrhage). A midline incision is carried down to the linea alba and the fascia is incised.
