Slide Study for Lab Practical Histology

8 slides Study location & function also On epi tissue: find apical surface & basement membrane then determine shape & layers Epithelial Tissue 8 slides Study location & function also

Simple Squamous Single row of flat cells

Simple Cuboidal

Simple Columnar

Psuedostratified Columnar Looks like layers but not distinct rows

Stratified Squamous

Stratified Cuboidal

Reminder: look at apical surface for shape Stratified Columnar

Transitional Does not have any particular pattern

Connective Tissue Slides On CT: find the one or two main features that let you ID the tissue

Areolar Long dark fibers

Adipose Large empty looking cells

Reticular Short dark fibers

Elastic CT Wavy stretchy looking fibers

Elastic Cartilage Cartilages are the only ones that have lacunae!! Lacunae (circles that contain cells) surrounded by matrix Elastic Cartilage

Hyaline Cartilage Lacunae (circles that contain cells) surrounded by matrix – This cartilage has more matrix than elastic cartilage

Fibrocartilage Lacunae (circles that contain cells) surrounded by matrix – This cartilage has even more matrix than hyaline cartilage

Blood

Compact (Osseous) Bone Circles like tree rings – called osteons

Spongy (Cancellous) Bone Looks like surface of a sponge Spongy (Cancellous) Bone

Dense Irregular Fibers run in no particular direction

Dense Regular Fibers only run in one direction
