Ch. 5 Tissue Organization Flashcards
What are the different types of tissues?
Epithelial, Connective, Muscle, Nervous.
What are the 5 characteristics of epithelial tissue?
Avascularity, polarity, attachment to the basement membrane, extensive innervation, and high regeneration capacity.
What are the four functions of epithelial tissue?
Physical protection, selective permeability, secretion, and sensation.
What are the classifications of epithelial tissue by shape?
Squamous, Cuboidal, and Columar
What are the classifications of epithelial tissue by layers?
Simple and Stratified.
What are the unique types of epithelial tissues?
Pseudostratified columnar and Transitional
What is the function of simple squamous epithelium tissue?
Allows rapid movement of molecules across the surface.
Where can you find simple squamous epithelial tissue?
Lungs, kidneys, vessel walls, serous membranes (mesothelium).
What are the functions of simple cuboidal epithelium tissues?
It absorbs fluids and secretes specific molecules for small ducts or glands.
Where can you find superficial cuboidal tissue?
Kidney tubules, secretory regions of glands, and surface ovary.
What are the functions of simple columnar tissue?
Ideal for secretory & adsorptive function
Where can you find simple columnar tissue?
Digestive tract, respiratory system, and urinary tubes.
What is the function of stratified squamous epithelium?
Protects against abrasion & friction
What are the 2 types of stratified squamous epithelium?
Nonkeratinized and Keratinized
Where is stratified squamous epithelium found?
(Nonkeratinized): oral cavity, esophagus, vagina, anus
(Keratinized): found in the epidermis
What are the functions of Stratified cuboidal epithelium?
Mainly protective functions
Where do you find stratified cuboidal epithelium?
Forms the walls of ducts of most exocrine glands.
What are the functions of stratified columnar epithelium?
Protects & secretes
Where can you find stratified columnar epithelium?
Found in large ducts of salivary glands.
What are the 2 types of glands?
Exocrine and endocrine glands.
What is the difference between exocrine and endocrine glands?
Endocrine glands secrete hormones and have no ducts, while exocrine glands have ducts and can move.
What are the three types of exocrine glands?
Merocrine, Apocrine, and Holocrine.
What are the characteristics of merocrine glands?
cleanest=freeist of cellular debris
What are the characteristics of apocrine glands?
Slightly messier; stinky sweat glands and mammary glands; more cellular debris than merocrine
