ACTUAL Exam Questions and CORRECT
Answers
Holocrine Glands - CORRECT ANSWER - entire cells are discharged as secretion
(sebaceous glands)
Merocrine glands - CORRECT ANSWER - secrete product through free surface, no loss of
cytoplasm/cell
Apocrine Glands - CORRECT ANSWER - secrete small amounts of cytoplasm/cell with
secretory product (mammary glands)
unicellular - CORRECT ANSWER - goblet cells
Multicellular - CORRECT ANSWER - tubular, alveolar/acinus
Serous secretion - CORRECT ANSWER - clear, watery with protein
Mucous secretion - CORRECT ANSWER - cloudy, mucin (glycoproteins) with water
Compound tubularv - CORRECT ANSWER - alveolar merocrine glands
intercalated duct - CORRECT ANSWER - he duct which is attached to an acinus or
terminal part of the gland
interlobar septa - CORRECT ANSWER - The connective tissue partitions between lobes
are
, interlobular septa - CORRECT ANSWER - he connective tissue partitions between lobules
Intercalated ducts - CORRECT ANSWER - hollow tube lined with simple cuboidal
epithelium flat cells that do not produce secretion only serve as passageway for saliva
Striated ducts - CORRECT ANSWER - connected to intercalated duct lined with simple
columnar epithelium cells which may have basal striation(mitochondria). Serves as passageway
for saliva and modifies by resorbing and excreting electrolytes
Excretory/Secretory ducts - CORRECT ANSWER - starts as pseudostratified columnar
epithelium and transforms to stratified cuboidal then ends as stratified squamous epithelium,
passageway for saliva
hypoplasia - CORRECT ANSWER - pitting of enamel because of poor matrix formation
(less than normal amount of enamel
Dental fluorosis - CORRECT ANSWER - mottled enamel, children exposed to more than
2ppm for 1st 8 years. Fluoride interferes with ameloblasts function
Abrasion - CORRECT ANSWER - abnormal wear cause by friction due to excessive tooth
brushing or use of abrasive toothpastes.
Erosion - CORRECT ANSWER - tooth structure lost through chemical means such as acid
from acid reflux, acidic foods/drinks or vomiting
Abfraction - CORRECT ANSWER - loss of tooth structure (wedge-shaped lesions) at the
cervical neck area of teeth from transmission of forces during occlusion and mastication. Caused
by compressive and tensile forces during tooth flexure.
What is acinus/acini? - CORRECT ANSWER - refers to any cluster of cells
