L1
| Term | Definition |
|---|---|
| epithelial tissue | many cells + little ECM |
| 2 types of epithelial tissue | membraneous and glandular |
| membraneous | cover the outer and inner surfaces of body organs and cavities |
| glandular tissue | made of epithelial cells that make and secrete a product |
| Glandular tissue 1 (Exocrine) | continuous with membrane epithelia have ducts and secrete locally onto surfaces and cavities uni or multicellular Ex: goblet cell (uni), mammy glands & sweat glands (multi) |
| Glandular tissue 2 (Endocrine) | lack ducts produce hormones that enter bloodstream target can be far away or nearby |
| Epithelia features | intercellular junctions join cells avascular but innervated all attached to basement membrane apical surface must face lumen (cavity) or open environment |
| how to classify epithelia | 1. number of cell layers 2. shape of cells |
| squamous | flat, wider than it is tall, oval nuclei |
| cuboidal | as wide as they are tall, circular nuclei |
| columnar | taller than they are wide, oval nuclei |
| transitional epithelia | can stretch and change shape umbrella cell found exclusively in urinary tract nucleus is round in top layer |
| goblet cell function | goblet cells produce mucus that lubractes the apical surfaces |
| Cilia | cilia move mucus across the apical surface |
| Simple Squamous Function | Diffusion and Filtration |
| Stratified Squamous Function | Protection |
| Simple Cuboidal & Columnar & Pseudostratified Function | Absorption and Secretion |
| Connective Tissue Functions | Surround and protect other structures, carry and store nutrients, support, immunity, insulate |
| Connective Tissue Fibers | Collagen (I and II) and Reticular (III) |
| Ground Substance | complex gel secreted by fibers that is made of hydrophilic molecules that help resist compression and increase flexibility |
| loose connective tissue proper | loos areolar, adipsose, reticular cushioning support |
| dense connective tissue proper | dense regular, dense irregular rigidity, motion and reisstance |
| Loose Areolar Connective Tissue | surrounds muscle, nerves and blood vessels retains body fluid cells that could be present; fibroblasts, blood cells, adipocytes, collagen and elastic fibers |
| Reticular Connective Tissue | forms a stroma that provides support for adipose, lymph nodes, bone marrow etc cells that could be present; fibroblasts, and reticular fibers |
| Adipose Connective Tissue | Lobulated fat cells arranged in a cluster maintains shape, cushions and provide insulation cells that could be present; adipocytes, reticular |
| Dense Regular | Fibers arranged in parallel Ligaments and Tendons |
| Dense Irreg | Fibers arranged randomly dermis of the skin |
| Superficial Fascia is made of.... | Loose Areolar and Adipose |
| Deep Fascia is made of.... | Dense Reg and Dense irreg |
