- lines body cavities what thelium is this
- mesothelium
- lines blood vessels, inner covering
- endothelium
- lines blood vessels and lungs
- simple squamos
- lines trachea
- pseudostratified columnar
- lines bladder
- transitional
- lines digestive tract
- simple columnar
- lines kidney tubules, ducts, part of ovaries
- simple cuboidal
- main function of simple squamos
- secretion, filtration
- main function of other simple tissues
- not very protective cuz thin so secrete and absorb
- stratified squamos u find
- epidermis, vagina, mouth
- purpose stratified squamos
- for high abrasion
- is stratified squamos the same throughout
- no on bottom layers have columnar and cuboidal
- lines the ducts and glands like mammary glands
- stratified cuboidal
- lines urethra and other ducts
- stratified columnar
- what is connective tissue made of
- ground substance, cells, and fibers
- what is ground substance
- extracellular matrix of the follwing kind: interstitial fluid, adhesion proteins, proteoglycans, its the background stuff
- what are the three kinds of fibers that youll find in connective tissue
- collagen, reticular, elastic
- collagen is made of, reticulicar is made of and elastic is made of
- collagen, collagen, elastin
- whats the difference bt collagen and reticular fibers
- made of same substance, reticular fibers just finer and have different functions, collagen is tough, reticular fibers provide a softer support
- describe relationship bt reticiular fibers and collagen
- collagen does the tough work and reticular fibers are continuous with it, providing support for more delicate stuff like support the soft tissue of organs and blood vessels (fuzzy soft packaging)
- where would u find elastic fibers
- where your body needs to stretch like the lungs and blood vessel walls
- whats the diff bt a fibroblast and fibrocyte
- blast is actively making the ground substance and fibers, cyte just maintaining it
- what kind of cells do you find in connective tissue
- macrophages, plasma cells, mast cells, macrophages, fibroblasts
- embryonic connective tissue
- mesenchyme
- mesenchyme forms from the
- mesoderm
- what are the two types of connective tissue
- loose and dense
- what are the three kinds of loose connective tissue
- reticular, aerolar, adipose
- what are the two kinds of dense connective tissue
- regular and irregular
- Loose connective tissue is more for....while dense connective tissue is more for....
-
loose; support
dense: resistance - givin the overall function of dense and loose tissue dense tissue since its all about resistance would be mostly made of
- collagen, with a few elastin fiber
- what is the role of aerolar tissue
- wraps and cushions organs, role for inflammation, hold tissue fluid, binds body parts
- what is the role of reticular tissue
- make a soft internal skeleton for cells
- what is the name of the soft internal skeleton that supports cells
- stroma
- what is the structure of reticular tissue
- just like aerolar but only reticular fibers
- what is aerolar tissue like
- has all fibers, very gooey cuz it has all this liquid and it has some scattered cells, soft packaging material
- where do you find aerolar tissue
- under epithelia, packaged around organs
- where do you find reticular tissue
- spleen, bone marrow, lymph organs
- three kinds of cartilage are
- hyaline, elastic, fibrocartilage
- adipose tissue is like
- aerolar but the fat crowds everything out, and its more compact
- cartilage is for
- tension and compression
- pits where you can find chondrocytes
- lacunae
- what makes elastic cartilage so flexible
- elastic fibers
- fibrocartilage is in between being
- dense regular connective tissue and hyalie cartilage
- what is hyaline cartilage made of
- lots of collagen and some chondrocytes
- what cartilage can provide the strongest support
- fibrocartilage
- how different is elastic cartilage from hyaline
- not much, just that elastic has elastin fibers
- whats in between vertebrae fibrocartilage or hyaline cartilage
- fibrocartilage, cuz its for the harder stuff
- where would u find hyaline cartilage
- tip of nose, connects ribs to sternum
- where would u find elastic cartilage
- epiglottis and external ear
- tendons and ligaments are made of regular dense connective tissue or irregular
- regular
- your dermis is made dense irregular or regular connective tissue
- irregular
- are the cutaneous, mucous, and serous membranes considered organs
- yes
- why is smooth muscle cause smooth
- cuz it has no striations
- funny but when u bleed do your blood vessels at first contract or dilate
- dilate to allow white blood cells and clotting proteins
- what is the first tissue to be formed at site of injury
- granulation
- whats the purpose of the organization stage
- restore blood supply
- granulation tissue eventually becomes
- scar tissue
- gland rupture to release product
- holocrine
- shapes for glands
- tubular, aveolar
