Stack #4604340
(1) epithelial tissues
| Question | Answer |
|---|---|
| Anatomy | the study of body parts and their relationship to one another |
| Physiology | the study of the function of body parts |
| homeostasis | maintaining a stable internal environment even though the external environment is changing |
| tissue definition | sheets or masses of similar cells |
| epithelia locations | linings, coverings, glands |
| epithelia lines... | the inside of cavities and internal organs |
| epithelia covers... | outside of body surface and outside of internal organs |
| epithelia forms... | glands |
| functions of epithelia | protection from microbes/chemicals/water/heat loss/friction, glandular secretions, absorption of nutrients |
| True or false: epithelia has blood vessels | false |
| true or false: epithelia has nerve endings | true |
| tight junctions | adjacent cell membrane proteins fuse to prevent things from moving between the extracellular spaces (ziplock bag) |
| desmosomes | anchor adjacent cell membrane proteins fuse, forming a reinforced structural unit. located where stretch is important, like the skin (velcro) |
| what are simple arrangements often for | absorption or filtration |
| where are stratified arrangements found | high areas of wear and tear |
| where is simple squamous | surface of membranes that line closed cavities and cover those organs |
| is simple squamous secretory | yes, it reduces friction around moving parts |
| is simple squamous permeable | permeable and adapted for diffusion and filtration |
| where is simple columnar | lines open tracts and ducts (digestive, reproductive) |
| what do simple columnar cell membranes form | microvilli (folds to increase SA of cell) |
| where does simple columnar absorb nutrients from | digestive tract |
| what does simple columnar contain | goblet cells |
| what do goblet cells produce | mucus |
| what is simple cuboid associated with | glands and their ducts |
| what covers the ovary and lines collecting ducts of the kidney | simple cuboid |
| true or false: stratified squamous sloughs easily | true |
| what is stratified squamous a protective barrier between | interior body and external environment |
| what does stratified squamous line | body openings and exits |
| True or false: stratified squamous forms outer layer of the skin (epidermis) | true |
| what does stratified columnar line | part of the male urethra |
| where is stratified cuboid | ducts of sweat glands |
| true or false: transitional is specialized to undergo changes in stretch/tension | true |
| where is transitional tissue | lines ureters and urinary bladder |
| where does pseudostratified (ciliated) columnar line | most of respiratory tract |
