COMPREHENSIVE QUESTIONS AND
ANSWERS STUDY GUIDE GRADED A+
●● Merocrine glands.
Answer: secrete product through free surface, no loss of cytoplasm/cell
●● Apocrine Glands.
Answer: secrete small amounts of cytoplasm/cell with secretory product
(mammary glands)
●● unicellular.
Answer: goblet cells
●● Multicellular.
Answer: tubular, alveolar/acinus
●● Serous secretion.
Answer: clear, watery with protein
●● Mucous secretion.
Answer: cloudy, mucin (glycoproteins) with water
,●● Compound tubularv.
Answer: alveolar merocrine glands
●● intercalated duct.
Answer: he duct which is attached to an acinus or terminal part of the
gland
●● interlobar septa.
Answer: The connective tissue partitions between lobes are
●● interlobular septa.
Answer: he connective tissue partitions between lobules
●● Intercalated ducts.
Answer: hollow tube lined with simple cuboidal epithelium flat cells that
do not produce secretion only serve as passageway for saliva
●● Striated ducts.
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.
Answer: starts as pseudostratified columnar epithelium and transforms
to stratified cuboidal then ends as stratified squamous epithelium,
passageway for saliva
●● hypoplasia.
Answer: pitting of enamel because of poor matrix formation (less than
normal amount of enamel
●● Dental fluorosis.
Answer: mottled enamel, children exposed to more than 2ppm for 1st 8
years. Fluoride interferes with ameloblasts function
●● Abrasion.
Answer: abnormal wear cause by friction due to excessive tooth
brushing or use of abrasive toothpastes.
●● Erosion.
Answer: tooth structure lost through chemical means such as acid from
acid reflux, acidic foods/drinks or vomiting
●● Abfraction.
