Anatomy & Physiology - Lab PracticalPink histological stain -H&E
Blue/black histological stain used for Connective Tissue -Silver stain
Histological stain used most commonly with Elastic Tissue -Verhoeff's stain
Exo- -Out, outside
Matrix-/mater- -Womb, mother
Epithe- -Laid on, covering
A- -Without
Vaso- -Vessel
Epithelial tissue is ______ ________, thus _________ -Packed together, avascular
Simple Squamous Epithelium function -Rapid diffusion or transport of substances across epithelium,
secretes lubricating serous fluid
Simple Squamous Epithelium locations -Alveoli (air sacs) of lungs, glomeruli (capillaries of kidneys),
endothelium (inner lining of chambers of heart and blood vessels), and serosa (outer lining covering
organs) & lining body cavities
Simple Cuboidal Epithelium functions -Absorption and secretion, mucus production and movement
Simple Cuboidal Epithelium locations -Liver (bile), thyroid (thyroid hormone), mammary and salivary
glands, bronchioles (of lung; mucus), and kidney tubules (urine production)
, Simple Columnar Epithelium functions -Absorption and secretion; secretion of mucus
Simple Columnar Epithelium locations -Lining of GI tract from stomach on (microvilli absorb
nutrients; mucus protects from acid), uterus (secretion of glycogen feeds the embryo) and uterine
tubes (cilia move egg), some kidney tubules
Pseudostratified Epithelium functions -Secretes and moves mucus
Pseudostratified Epithelium -Respiratory tract (from nasal cavity to bronchi); portions of male
urethra)
Keratinized Stratified Squamous Epithelium functions -Resists abrasion and stress; retards water loss
through skin (keratin also extremely hydrophobic); resists penetration by pathogens
Kerato- -Horn
Keratinized Stratified Squamous Epithelium locations -Epidermis (outer layer of all skin); palms and
soles are heavily keratinized
Non-keratinized Stratified Squamous Epithelium functions -Resists abrasion and penetration of
pathogens, but will remain moist
Non-keratinized Stratified Squamous Epithelium locations -Tongue, oral mucosa, esophagus, and
vagina (after puperty; prior to puberty the lining is a simple columnar epithelium)
Stratified Cuboidal Epithelium functions -Secretes gland products; produces some reproductive
hormones, aids in production of sperm
Stratified Cuboidal Epithelium locations -Sweat gland ducts; found in some salivary glands and
mammary glands; ovarian follicles and seminiferous tubules (in testes)
Transitional Epithelium functions -Stretch; allows for filling of urinary tract
Transitional Epithelium locations -Ureter (carry urine from kidneys to bladder) and bladder
