Tissues Flashcards
Epithelial
Forms boundaries between different environments, protects, secretes, absorbs, filters
Nervous
Internal communication
Muscle
Contracts to cause movement
Connective
Supports, protects, binds other tissues together
Characteristics of epithelial tissue
- Thin 6. Innervated
- Continuous sheets 7. Polarized
- Little interstitial space 8. Regenerate quickly
- Little interstitial matrix
- Avascular
Simple
One cell thick epithelium
Stratified
Layered epithelium
Squamous
Flat
Cuboidal
Cube shaped
Columnar
Tall and thin cells
Simple columnar (2)
Ciliated non ciliated
Pseudostratified
Simple epithelium that seems stratified
Goblet cell
Glandular cell that makes mucus
Simple squamous
Keratinized- epithelium
Unkeratinized- mouth
Transitional epithelium
Stretches and changes shape
Glandular epithelium
Product is always a secretion
Made from water and protein
Exocrine
All cells start out exocrine
Multicellular exocrine have ducts
Send secretion outside the body or extension of the enviroment
Simple duct
Duct does not branch
e.g. Simple tubular; simple branched tubular (only comes off of main branch)
Compound duct structure
Many duct branches
e.g. Compound alveolar, tubular
Tubular structure
Cells form tubes
Alveolar structure
Flask like structure
Merocrine gland
Secrete by exocytosis e.g. Sweat gland
Holocrine gland
Cells accumulate until they rupture and are replaced by other cells
