Chapter 5 Flashcards
What are the two broad categories of epithelia tissue?
1) simple epithelium
2)stratified epithelium
what are the four types of simple epithelium tissue?
1) Simple squamous (one layer of flattened cells)
2)simple cuboidal (one layer of cells about as tall as wide…inside of your kidney)
3) simple columnar (one layer of tall, narrow cells)
4) Pseudostratified (one layer of tall cells that appears stratified)
what are the four types of stratified epithelium tissue?
1) Stratified Squamous (multiple layers; upper layers off flattened cells)
2)stratified cuboidal (two or more layers; cells about as tall as wide
3) stratified columnar (two or more layers of tall, narrow cells)
4)transitional (multiple layers of cells that change shape when stretch)
What are the two different types of stratified squamous cells?
1) keratinized (superficial cells are dead)
2) nonkeratinized (superficial cells are living)
Where are simple squamous epithelium cells found?
air sacs in the lungs (alveoli; lining of the lumen of blood vessels and lymph vessels (endothelium, serous membranes of body cavities (mesothelium)
Where are simple cuboidal epithelium cells found?
kidney tubules, thyroid gland follicles; surface of ovary; secretory regions and ducts of most glands
Where are nonciliated simple columnar epithelium cells found?
the lining of most of the gastrointestinal (digestive) tract (stomach, small intestine, and large intestine)
Where are ciliated simple columnar epithelium cells found?
lining of the larger bronchioles (air passages) of the lungs and the uterine tubes
Where are ciliated pseudostratified columnar epithelium cells found?
The lining of the larger airways of the respiratory tract, including the nasal cavity, part of the pharynx, part of the larynx, trachea, and broachi
Where are nonciliated pseudostratified columnar epithelium cells found?
Rare- lining of part of the male urethra and epididymis
Where are keratinized stratified squamous epithelium cells found?
epidermis of skin
Where are nonkeratinized stratified squamous epithelium cells found?
lining of the oral cavity, part of the pharynx, part of the larynx, esophagus, lining of the vagina, and anus
Where are stratified cuboidal epithelium cells found?
ducts of most exocrine glands and ovarian follicles
Where are stratified columnar epithelium cells found?
large ducts of salivary glands; conjunctiva covering the eye; lining of the membranous part of the male urethra
Where are transitional epithelium cells found?
lining of the urinary bladder, ureters, and part of the urethra

What are the two types of connective tissue proper
1)Loose connective tissue (fewer fibers, more ground substance
2)Dense connective tissue (more fibers, less ground substance
What are the three types of loose connective tissue?
1)Areolar
2)Adipose
3)Reticular
What are the two types of supporting connective tissues?
1)Cartilage (semisolid matrix)
2)Bone (Solid matrix)
What are the three types of cartilage?
1)Hyaline
2)Fibrocartilage
3)Elastic
What are the two types of bone?
1) Compact
2) Spongy
What are the two types of fluid connective tissues?
1)Blood
2) Lymph
