|
Tissue |
group of cells with common function |
|
|
Simple Squamous Epithelium |
One layer of cells, squished
Located: ventral body cavity, lining of heart, blood vessels |
|
|
Stratified |
Many layers |
|
|
Stratified Squamous Epithelium |
Many layers, squished
Located: throat, lining of mouth |
|
|
Keratinized stratified squamous epithelium |
dead cells, you will not see a nuclei on most superior layer |
|
|
Non-keratinized stratified squamous epithelium |
No dead cells, you will see nuclei all the way to the top |
|
|
Simple Cuboidal Epithelium |
One layer and cube shaped
Located: glands, ducts |

|
Stratified Columnar Epithelium |
Many layers and column shaped
Located: glands |
|
|
Endocrine |
secretes into body directly
|
|
|
Exocrine |
secrete through ducts. Products go to places "outside" (surface of) the body
Examples: sweat glands, salivary glands, mammary glands, liver |
|
|
Basics of tissues picture |
|
|
|
Apical surface |
top of cell |
|
|
Basal surface |
near bottom of cell, but not the most distal part |
|
|
Basement membrane |
Layer of fibers that attach an epithelium to the underlying connective tissue |
|
|
Pseudostratified Ciliated Coumnar Epithelium |
Located: lining of nasal cavity and trachea
*look for cilia |
|
|
Goblet Cells |
goblet shaped, mucus-producing, unicellular exocrine gland |
|
|
Cilia |
Slender organelle that extends above the free surface of an epithelial cell, generally undergoe cycles of movement and are composed of basal body and microtubules |
|
|
Merocrine secretion (exocrine secretion classification) |
method of secretion in which the cell ejects materials from vesicles through exocytosis |
|
|
Apocrine secretion (exocrine secretion classification) |
A mode of secretion in which the glandular cell sheds portions of its cytoplasm |
|
|
Holocrine secretion (exocrine secretion classification) |
secretory cell becomes swollen with vesicles and then ruptures, the mature cell dies as a result |
|
|
Major Endocrine Glands (picture) |
