Epithelial
sheets of cells that line internal and external body surfaces
-avascular and regenerative
Connective
support tissues where specific cell type is embedded within acellular (non living) matrix
Muscle
excitable tissues capable of contraction
Nervous
excitable tissues capable of transferring and integrating signals from one part of the body to another
Simple Epithelia
single layer of cells
Stratified Epithelia
multiple layers of cells from two to many layers
Squamous Cells
flat and individual cells are wider than they are tall
Cuboidal cells
cube shaped and individual cells are same width as height
Columnar Cells
column shaped and individual cells are taller than they are wide
Simple Squamous Epithelium
-single layer of flattened cells
-found in kidney, lungs, lining of blood vessels, and heart
Simple Cuboidal Epithelial
-necessary in absorption and secretion
-in kidney tubules, ducts, and secretory portions of small glands, and ovary surface
Simple Columnar Epithelium
-ciliated and contains goblet cells
-lines digestive tract, gallbladder, small bronchi, uterine tubes
Pseudostratified Columnar Epithelium
-single layer of tall cells with different heights
-found in trachea, sperm, ducts of large glands
Stratified Squamous Epithelium
-protection from abrasion
-epidermis of skin, mouth, esophagus, stomach, and vagina
Stratified Cuboidal Epithelium
-usually two layers of cuboidal cells
-protection
-largest ducts of sweat glands, mammary glands, and salivary glands
Stratified Columnar Epithelium
-several layers of tall cells
-protection and secretion
-male urethra and large ducts and some glands
Transitional Epithelium
-changes from stratified cuboidal to stratified squamous depending on state of stretch of organ
-allows organ to stretch
-ureters, urinary bladder, part of urethra
