Epithelia
Where do glands developed from and what kinds are there?
Epithelial tissue
Endocrine and Exocrine glands
Which glands internally release and which glad release externally?
Which glands have a duct?
Internally-Endocrine glands
External-Exocrine glands
Exocrine glands have a gland
What are the finger like extensions of the plasma membrane?
Microvilli
What are the 4 mains types of C.T and where do they originate from?
Connective Tissue Proper, Cartilage, Bone, and Blood. They originate from mesenchyme.
What are the Loose C.T and Dense C.T (fibrous)?
Loose: Areolar, Adipose, and Reticular
Dense: Regular, Irregular, Elastic
What is transitional epithelia made of and what is its function?
Made of a stratified squamous epithelia and allow stretch unrinary system organs
What and where do exocrine glands release?
They release hormones into the blood or lymphatic vessles.
What are the main junctions for binding cells together?
Desmosomes
Besides coming from mesenchyme. What are the other 3 characteristics of C.T.?
Very well vascularized, composed of many cell types, and lastly have a matrix.
T/F reticular fibers are the only fibers found in Reticular connective tissue?
True
Example: Bone Marrow
Which epithelia’s function is secretion and absorption?
Simple cuboidal epithelium
What are goblet cells?
Cells that produce mucin that when comes in contact with water creates mucus
What are the tight belt like junctions
Tight junctions
Ground substance holds interstitial fluid and what else?
Fibers:
-Collagen Fibers
-Elastic Fibers
-Reticular Fibers
Which fibers run in the same direction and which fibers run in different planes?
Same direction-Dense regular C.T.
Different-Dense irregular C.T.
How do we classify epithelial cells?
By looking on the apical surface and how many layers.
What are the classifications and categories of multicellular exocrine glands?
Classifications-Simple and Compound
Categories-Tubular, Alveolar, and tubuloalveolar
What makes up the basement membrane?
Basal Lamina and reticular fibers
What fiber can withstand tension?
Which fiber supports bordering C.T.?
Which fiber can snap back?
Collagen

What is the tunnel like passage way between adjacent cells?
Gap Junctions
Besides ground substance and fibers what else does areolar C.T. do?
Fight off infection with defense cells, and stores nutrients witch fat cells.
What is the prototypical C.T.
Areolar
