Q1 Station 5 Epithelial tissue Flashcards
Name four primary types of tissues
Connective
Muscle
Epithelial
Nervous
Describe four essential functions of epithelial tissue?
protection
secretion
permeability
sensation
Epithelial tissues classification is based on types of layering. What are the two types??
Simple and Striated
What are the three types of cell shapes in epithelial tissue?
Squamous
columnar
cuboidal
Simple comes in what cell shapes?
cuboidal
columnar
squamous
Striated comes in what shape?
Squamous
pseudo striated cells are usually what kind of cell?
ciliated columnar (cilia)
Simple squamous epithelium:
where does this tissue occur?
wherever small molecules must pass across a membrane quickly
Simple squamous epithelium:
Name the different localized tissue (2)
Mesothelia
endothelia
Simple squamous:
Where is the location of the mesothelia found?
lining of ventral body cavity
Simple squamous:
where is endothelia found?
found in Lining of heart, blood vessels, kidney tubules, cornea, alveoli
Simple cuboidal epithelia:
Where is simple cuboidal found?
glands, ducts, kidney tubules, thyroid gland
Simple cuboidal epithelia:
What is its general function?
limited protection
surrounds glands
secretion and absorption
Simple columnar epithelium:
What are its functions?
Protection
secretion
absorption
Simple columnar epithelial:
where is it located?
stomach
intestines
gallbladder
uterine tube
Stratified squamous epithelium:
what are its main function ?
Protection from abrasion, chemicals, pathogens
Stratified squamous epithelial:
Where is it located?
Skin mouth throat rectum esophagus vagina
Stratified squamous epithelial:
Name the two types of this epithelium and its location for each.
Karatinized - surface of body
Nonkeratinized - oral cavity, pharynx, esophagus, rectum, anus, vagina
Transitional epithelium:
found in what locations?
urinary bladder
renal pelvis
ureters
Transitional epithelium:
what is its function?
expansion and recoil
pseudo stratified ciliated epithelium:
Where is its specific locations?
nasal
trachea
bronchi
male reproductive tract
Pseudo striated ciliated epithelial:
what are its functions>
secretes
protects
Glands:
Exocrine glands do what?
discharge secretions directely onto epithelial surface
Glands:
exocrine glads are one of two things
Multicellular
unicellular
Glands:
What are the only two types of unicellular exocrine glands?
Mucous cels
Goblet cells
Glands:
Both mucous cels and goblet cells secret what?
Mucins
Glands:
When mucous cells and goblet cells secreted mucins mixes with water what does it form?
it will form mucus
Glands:
Where would you find mucous cells?
pseudo striated columnar epithelium in trachea
Glands:
What are two examples of multi cellular exocrine glands found in the skin?
sebaceous gland
Sweat gland
