TCDHA HISTOLOGY MIDTERM EXAM
2024-2025
Holocrine Glands: Sebaceous glands release whole cells as secretions.
Merocrine glands: ANSWER release a product via their free surface
without losing any cell or cytoplasm.
Apocrine Glands: The mammary glands produce minute amounts of
cytoplasm or secretory substance.
ANSWER goblet cells are unicellular.
Multicellular: alveolar/acinus, ANSWER tubular
Serous secretion: ANSWER protein-rich, transparent
Answer: hazy, mucin (glycoproteins) with water in mucous secretion
Compound tubular - ANSWER merocrine glands in the alveoli
intercalated duct: ANSWER the duct that connects to the gland's
terminal portion or acinus
interlobar septa - ANSWER The lobe-to-lobe connective tissue divisions
are
The connective tissue divisions between lobules are called interlobular
septa.
Saliva passes through intercalated ducts, a hollow tube lined with flat,
simple cuboidal epithelial cells that do not secrete anything.
Striated ducts: ANSWER attached to an intercalated duct that is lined
with cells that are simple columnar epithelium and may have
, mitochondria (basal striation). allows saliva to pass through it and
changes by reabsorbing and excreting electrolytes.
Saliva passes through the excretory/secretory ducts, which are initially
pseudostratified columnar epithelium, then change into stratified
cuboidal epithelium and finally stratified squamous epithelium.
Hypoplasia: ANSWER pitting of enamel due to inadequate matrix
formation (deficiency in enamel content).
Dental fluorosis: children exposed to more than 2 ppm for the first eight
years will have mottled enamel. Fluoride disrupts the function of
ameloblasts.
Abrasion: ANSWER excessive wear brought on by friction from using
abrasive toothpastes or excessive teeth brushing.
Erosion: Removing tooth structure chemically by vomiting, acid reflux, or
eating or drinking acidic foods or beverages
Abfraction is the term used to describe the loss of tooth structure
(wedge-shaped lesions) at the cervical neck area of teeth as a result of
forces transmitted during mastication and occlusion. caused by the
forces that compress and tension during the flexing of teeth.
Acini, or acinus, what? ANSWER denotes any group of cells.
What kind of acinus surrounds its epithelium? - A single layer of cuboidal
epithelial cells makes up the ANSWER.
ANSWER Compound tubular-alveolar merocrine glands are the salivary
glands.
ANSWER's exocrine glands contain a duct.
simple duct: ANSWER one non-branching duct
