Tissue Types Flashcards
Four tissue types
Epithelial, connective, muscle and nervous
Epithelial tissue
Lines other tissues; has exposed surface; polar, junctional complexes, a vascular, most innervated
Basement Membrane
Cements epithelial cell to underlying connective tissue
Functions of epithelial
Protective/sensory, absorptive, filter and excretion/secretion
Surface specialization
Microvili, cilia and keratin
How to classify epithelial cells
1) how many layers?
2) what shape are they?
Simple
One layer of epithelial cells
Stratified
More than one layer of epithelial cells
Squamous
Squished or flat cell
Cuboidal
Cube shaped cells
Columnar
Coleman shaped with nucleus in a row
Types of epithelial tissue
Simple squamous
Simple cuboidal
Simple columnar
Stratified squamous
Stratified cuboidal
Pseudostratifed columnar
Transitional
Connective tissue
Extracellular fibers, ground substance and cells
Connective tissue definition
Surrounds&separates cells and organs
Important structural and nutrional support
Tendons and ligaments
Connects, insulates, absorbs
Vascular
Extracellular fibers
Collagenous, reticular and elastic
Ground substance
Amorphous, homogenous material/ gel, liquid and calcified solid
Cells
Fibroblast, adipocyte, reticular
What makes the matrix?
Fibers+ground substance
Loose connective tissue
Areolar, adipose and reticular
Dense connective tissue
Dense regular, dense irregular and elastic
Specialized connective tissue
Cartilage, bone and blood
Muscle tissues
Skeletal, smooth and cardiac
Skeletal muscle
Voluntary/ striated
Smooth muscle
Involuntary/ no striations
Cardiac muscle
Involuntary/striated/intercalated disks
Nervous tissue
Neurons
