Module 2: Tissues of the Perio part 2 (10 questions) Flashcards
what is ground substance composed of
collagen, elastin, reticular fibers
Connective Tissue is composed greatly of
ground substance compared to the number of cells
This lines the cavity of the mucosa
epithelium
What type of cells make up the epi
squamous stratified epi
does epic have a high or low amount of extracellular matrix
low
This type of tissue supports and binds tissues
Connective tissue
Cementum, dentin and pulp chamber are specialized
connective tissue
enamel is a specialized
epithelial tissue
this does the epithelium and the connective tissue meet
in the wavy tissue boundary
What are the parts of the wavy boundary
epithelial ridges(rate pegs) and connective tissue papillae
Wavy tissue boundary increases
adhesion due to increased surface area and more nourishment to the epithelium
what is an epithelial cell junction
mechanically attach a cell and its cytoskeleton to another cell or basal lamina
what is a desmosome
they connect two neighbouring epithelial cells and their cytoskeletons together
what is a hemidesmosome
a specialized cell junction that connects the epithelial cells to the basal lamina
what are the anatomical areas of the gingival epithelium
Oral Epithelium, Sulcular Epithelium and Junctional Epithelium
What is keratin
tough fibrous structural protein that occurs in the outer layer of the skin
What is the keratinization of Oral Epithelium
Keratinized or parakeratinized
What are the layers of OE
Keratinized layer, granular cell layer, Prickle cell layer, basal cell layer
What is the keratinized cell layer
flattened cells with extensive intracellular keratin
The granular cell layer consists of
flattened cells and increased intracellular keratin
the prickle cell layer is
spikelike cells with large intercellular spaces
the basal layer
cube shaped cells
The basal layer and the prickle cell layer attach by
desmosomes
The layers of the sulcular epithelium are
superficial cell layer, prickle cell layer, basal cell layer
Is the SE keratinized
no
is the junctional epi keratinized
no
the superficial cell layer is
flattened cells with no keratin
the layers if JE are
Basal layer and prickle cell layer
what are the types of basal lamina JE has
internal and external basal lamina
what is the internal basal lamina
between the epic cells and the tooth
What is the external basal lamina
between the epi cells and the CT
