| Question | Answer |
|---|---|
| What is the term for one layer? | simple |
| What is the term for more than one layer? | stratified |
| What is the term for false layered? | pseudostratified |
| What is the term for flat shape? | squamous |
| What is the term for cube shape? | cuboidal |
| What is the term for rectangular shape? | columnar |
| What is the term for the ability to change shapes? | transitional |
| Where are epithelial tissues found? | throughout the body |
| What do epithelial tissues do? | they cover organs, form inner lining of body cavities and line hollow organs |
| What is simple squamous epithelium? | a single layer of thin flattened cells, fit tightly together with broad thin nuclei |
| Where can you find simple squamous epithelium? | wall of capillaries, lining inside of blood vessels, lining air sacs in the lungs |
| What is simple cuboidal epithelium? | a single layer of cube shaped cells with a centrally located spherical nuclei |
| Where can you find simple cuboidal epithelium? | covering the ovaries, lining most of the kidney tubules |
| What is simple columnar epithelium? | longer than they are wide, single layer of cells with elongated nuclei usually located at or about the same level near the basement membrane. |
| Where can you find simple columnar epithelium? | uterine tube (w/cilia), lining uterus, portions of the digestive tract (w/o cilia) |
| Is simple columnar epithelium ciliated or not? | both |
| What is pseudostratified columnar epithelium? | they appear layer but are not - nuclei lie at two or more levels in the row of aligned cells (different depths) |
| Where can you find pseudostratified columnar epithelium? | lining the passage of the respiratory system |
| What is stratified squamous epithelium? | relatively thick tissue with newer cells on the bottom, underneath |
| Where can you find stratified squamous epithelium? | this forms the outer layer of skin, lines the oral cavity, esophagus, vagina, and anal canal |
| What is stratified cuboidal epithelium? | it consists of two or three layers of cuboidal cells |
| Where can you find stratified cuboidal epithelium? | lining the ducts of the mammary glands, sweat glands, salivary glands and pancreas |
| What is stratified columnar epithelium? | several layers of cells with superficial cells being columnar and basal layers being cuboidal |
| Where can you find stratified columnar epithelium? | part of the male urethra, lining the larger ducts of exocrine glands |
| What is transitional epithelium? | specialized to change in response to increased tension |
| Where can you find transitional epithelium? | lining the uterus, urinary bladder and superior urethra |
| What is glandular epithelium? | cells specialized to produce and secrete substances into ducts or into bodily fluids |
| Where can you find glandular epithelium? | glands |
| What is an exocrine gland? | a gland that secretes its product into ducts that open onto surfaces (exo=exit) |
| What is an endocrine gland? | a gland that secretes its product into tissue fluid or blood |
| What is a merocrine gland? | a gland that releases fluid by exocytosis |
| Name a merocrine gland | salivary gland, pancreatic glands, sweat glands |
| What is an apocrine gland? | a gland that loses a small portion of the glandular cell bodies during secretion |
| Name an apocrine gland | mammary glands, ceruminous glands lining the external ear canal |
| What is a holocrine gland? | a gland that releases entire cells that disintegrate to release cell secretions |
| Name a holocrine gland | sebaceous glands of the skin |
