simple squamous epithelium - flattened - 1 layer

stratified squamous epithelium -multiple layers -squished

simple cuboidal -same shape - 1 nucleus

stratified cuboidal epithelium -multiple layers -square shaped -nucleus in middle

simple columnar epithelium -1 layer -nucleus in similar place -1 nucleus

pseudostratified columnar epithelium -appears to be multiple layers, but is 1 -columnar cells appear to be 1 layer

hyaline cartilage

elastic cartilage

fibrocartilage

dense regular connective tissue -consistent direction of fibers

dense irregular connective tissue -different directions

areolar tissue -elastic fibers=straight lines -collagenous fibers=translucent lines -fibroblasts=cells

adipose tissue white, thin plasma membrane

reticular connective tissue

blood -platelets=little balls -erythrocytes=red blood cells -leukocytes=multiple nuclei

skeletal muscle -straight(fibers) -striations -clear nuclei

cardiac muscle -branching -slight striation -intercalated discs(where it looks more opaque)

smooth muscle -no striations
