2. Count the layers
Simple: 1 layer
Stratified: looks and is several layers
Pseudostratified / Transitional: Looks like several
layers, but all the cells contact the basement membrane
What cell is on the top layer?
Squamous: Flat (scaly)
Cuboidal: about as wide as it is tall
Columnar: much taller than it is wide
3. Singlelayer of thin squamous cells resting on
a basement membrane
Location:
Air sac of lungs
Forms the walls of capillaries
Forms serous membranes
Membranes that lines the ventral body cavity and
cavity and covers the organs inside it
5. Location
Common in glands and
their ducts
Forms walls of kidney
tubules
Covers surface of
ovaries
• A cluster of ducts in the pancreas
• Top layer of the cell is as wide as it is
thick
6. Location
Line entire length of the digestive track from
stomach to anus
Located in digestive tract
7. Nonciliated type in male’s sperm-carrying
ducts of large glands; ciliated variety lines
the trachea, most of the upper respiratory
tract
9. Nonkeratinized type forms the moist linings
of the esophagus and mouth; keratinized
variety forms the epidermis of the skin, a dry
membrane.
10. Little black dots
nuclei, mid-section
stratified squamous
epithelium, right below
that basement
membrane, lastly
connective tissue
11. Lines
the ureters, bladder, and part of the
urethra
Top pinkish purple is the
transitional
epithelium, and then the
lighter purple is the
basement
membrane, then
connective tissue
23. • Inflammatory, chronically
relapsing, non-contagious and itchy
skin disorder
• Type of eczema
• Also known as "prurigo Besnier,"
"neurodermitis," "endogenous
eczema," "flexural eczema,"
"infantile eczema," and "prurigo
diathésique
24. Cause is genetic
Aggravated by
contact or intake
of allergens
Also influenced by
other factors
affecting the
immune system
Ex. stress and
fatigue
25. Idiopathic- no certain
cause
Changes in at least 3
groups of genes
encoding structural
proteins, epidermal
proteases and
protease inhibitors
may lead to a
defective epidermal
barrier
26. can’t keep in moisture
can’t keep out irritants
disturbs the formation
of natural skin oils
reduces sweat secretion
skin can become so dry
that it cracks and
fissures develop
allowing bacteria and
irritants to penetrate the
skin
possibly cause infection
