Epithelium Flashcards
This type of epithelium is involved in gross filtering of particulates and movement of mucus
What can and cannot cross this structure (basement membrane)?
Can: solutes, water, nerve fibers
Can’t: blood vessels, cells (except in cancer)
What type of gland is this?
Coiled tubular exocrine
This type of gland is formed from the proliferation and invagination of epithelial tissue
Name the epithelium and the tissue
Stratified (nonkeratinized) squamous
Esophagus
Name the epithelium, the tissue, and the indicated structure
Simple columnar (ciliated)
Small intestine
Goblet cells
Name the epithelium and 3 places where this type of epithelium is found
Simple columnar
- Stomach, small and large intestine
- Gallbladder
- Uterine tubes and some of uterus
Does this tissue have glands? If yes, identify them, and state what type they are.
Yes
Tubular exocrine
Name the epithelium
Simple cuboidal
What tissue is this, what type of epithelium is it, and what other structure(s) have this same type of epithelium?
This is kidney
Simple cuboidal epithelium
Many ducts and exocrine glands, including pancreas
What is the black structure made of, and what produces it?
Basement membrane: type IV collagen, many glycoproteins especially laminin
Name 2 weak(er) cell junctions
Tight junctions
Gap junctions
Name the epithelium and apparent tissue
Simple columnar
Large intestine (based on few goblet cells and glands)
Name the epithelium and the organ system where it is found
Transitional epithelium
Urinary tract including bladder
What type of junction attaches epithelial cells to the indicated structure?
Hemidesmosomes
All epithelia have lots of _____ and very little _____
Lots of cells
Little ECM
Name 2 anchoring junctions and the protein they have in common
Desmosomes and Adherens
Cadherens
Name the epithelium and where it is found
Pseudostratified ciliated columnar
Upper respiratory tract
Name the epithelium and the indicated structure
Stratified (keratinized) squamous
Basement membrane
Name the epithelium and tissue
Simple cuboidal
Kidney
Epithelium that is responsible for absorption and/or secretion of relatively few, or relatively simple, nutrients, solutes, hormones, etc.
Where is this type of epithelium found and how do its structural features help with its function?
Pseudostratified ciliated columnar
Upper respiratory including trachea
Name the epithelium
Simple cuboidal
Describe clinical effects of thickening or thinning/destruction of the indicated structure (darkest blue) in this tissue type, as well as some causes.
Thinning/destruction: excess solutes, protein, blood in urine (depending on severity); causes: hyperglycemia, hypertension, autoimmune glomerulonephritis, lupus, genetic diseases, etc.
Thickening: cells don’t get enough nutrients, die off; not enough filtering; causes: scarring (post-thinning/destruction), hyperglycemia
Name the epithelium, the tissue, and 4 places where this type of epithelium is found
Stratified squamous
This is skin (keratinized)
- Skin (keratinized)
- Vagina (nonkeratinized)
- GI: Esophagus, mouth, anus (nonkeratinized)
- Urethra (nonkeratinized)
Name the epithelium and its function
Transitional
Allows for distension (cells flatten when distended), small amount of protection due to more layers of cells, protection from infection due to more layers of cells
Name the 2 types of gland in this image and identify them
This epithelium is found in organs where frequent distension is necessary
Name the epithelium and identify the indicated structure
Pseudostratified ciliated columnar
Cilia
Name the epithelium and identify the basement membrane
Transitional
Epithelium where complex absorption and secretion take place
avascular connective tissue that prevents (e.g., malignant) downward epithelial growth or upward connective tissue growth
