Give an Example of where you can find the following types of skin:
Non karatinized: Keratinikzed: Collagen and Keratinocytes |
Non karatinized: face- bleeds easy
Keratinikzed: heel, (doesn’t bleed easy) or callus collagen and keratinocytes: scar |
|
|
name 4 places where Transitional Eipthelium is found
|
Renal calyces
Ureter BLADDER urethra |
|
|
what is Transitional Epitheliums Characteristic look?
|
peeping out above the crowd
|
|
|
what are the 3 components of the Secretory portion of multicellular gland?
|
○ tubular
○alveolar (flask) ○ acinar (sac) |
|
|
Define two main types of glands
|
Serious: water based, carries enzymes, stains pink
Mucous: no stain (M for Minus stain), nucleoli |
|
|
90% of glands are ___shaped
|
acinar
|
|
|
where Stratified Squamous is found (3) ? and how is it classified?
|
• Epidermis
• lining of oral cavity / esophagus • lining of vagina Can be classified as keratinized or nonkeratinized |
|
|
Stratified Columnar Epithelium is organized how?
|
linear – one layer stuck to BM
|
|
|
where is Stratified Cuboidal/Columnar epithelium found? (3)
|
Sweat gland ducts
anorectal junction large ducts of exocrine glands |
|
|
where is Pseudostratified epithelium found (3)
|
• Conducting portion: Trachea and bronchi lining
• Lining of vas deferens • Epididymis |
|
|
where is Simple Columnar found? (3)
what does simple mean? |
• Small intestine and colon lining
• gallbladder lining • stomach lining and gastric glands Simple: every cell is attached to Basement Membrane Think GI for columnar Digestive System!!! |
|
|
Simple Cuboidal is found where?
|
• Small ducts of exocrine glands kidney tubules
Used highly in glands: ---Nuclei are organized: epithelium ---Cuboidal: equal cytoplasm on all four sides |
|
|
Simple Squamous functions as a ______ and is found in_____ (3)
|
• Lining of vascular system (blood/lymph)-endothelium.
• Lining of body cavities (mesothelium) • Lining of respiratory spaces in lung (type I pneumocyte) Bowman’s capsule in kidney Found in alveoli, bowman’s capsule. Anywhere you need a very fine filtrate system. It lines every artery, vein, what not: gas exchange |
|
|
what is special about epithelial cells when it comes to life and death?
|
Regenerates much quicker than any other – look for highest concentration of nuclei
|
|
|

Simple squamous simple cuboidal simple columnar pseudostratified stratified cuboidal/ columnar stratified squamous transitional |
Simple squamous - alveoli, vascular system
simple cuboidal- Glands simple columnar- Digestive System pseudostratified- Vas Deferens stratified cuboidal/ columnar- sweat gland ducts, anorectal junction stratified squamous- mucosal surfaces transitional- bladder |
|

what is the quickest and easiest to produce? |
most protective: stratified squamous
Quick and easy: columnar |
