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