how many kinds of tissues are there and what are their names
4
epithelial
connective
muscle
nervous
what is homeostasis
the relative constancy of the internal environment
expand on fluid material in cells
each tissue differs in the amount/kind of fluis it has in its cells
what is the difference between collagen and elastin
- collagen is a protein that gives tissues flexible stength
- elastin gives tissues the ability to stretch/rebound easily
expand on epithelial tissues
- forms sheets that cover the body and forms ducts/tubes
- contains no blood vessels
- the basement membrane (gluelike structure) connects it to its connective tissue foundatiom
how many kinds of epithelial tissues are there and what are their names
6
simple squamous
stratified squamous
simple cuboidal
simple columnar
pseudostratified
staratified transitional
expand on simple squamous epithelial tissue, where its found and its function
- single layer of flattened cells
- found in alveoili, lining of blood and lymphatic vessels
- functions are diffusion, filtration, osmosis
expand on stratified squamous epithelial tissue, where its found and its function
- has many layers
- outermost layer is flattened cells
- found in surface of skin and lining of mouth/esophagus
- function is protection
expand on simple cuboidal epithelial tissue, where its found and its function
- single layer of cells that are as tall as they are wide
- found in glands, kidney tubles
- functions is secretion, absorption
expand on simple columnar epithelial tissue, where its found
- single layer of tall, narrow cells
- found in surface layer lining of stomach, intestines, respiratory tract, fallopian tubes
expand on pseudostratified epithelial tissue, where its found and its function
- single layer of tall cells that wedge together to appear as if there were more layers
- found in the lining of the respiratory tract, male reproductive tract
- function is protection (by cilia/mucus)
expand on stratified transitional epithelial tissue, where its found and its function
- many layers of varying shapes
- found in urinary bladder
- function if protection
expand on connective tissues
- most abundant and wildly distributed tissue in the body
- found in skin, membranes, muscles, bones, nerves, internal organs
- connects tissues to each other and forms a supporting framework for the body
how many types of connective tissues are there and what are their names
8
loose fibrous (areolar)
adipose (white and brown fat)
reticular
dense fibrous (irregular and regular)
bone (compact and cancellous)
cartillage (hyaline, fibrocartillage and elastic)
blood
hematopoietic
what is loost fibrous (areolar) connective tissue, where is it found and what is its function
- loose arrangement of collagen fibers, elastic fibers, cells
- found in fascia
- function is connection
what is asipose connective tissue, where is it found and what is it’s functions
- contains triglyceride vesicles
- white fat is found under the skin and its function is protection, insulation, support, nutrient reserve and regulation
- brown fat is found under the pocket of white fat such as the neck and torso and its function is heat production and regulation
expand on reticualr connective tissue, where is it found and what is its function
- network of fine collagen fibers
- found in bone marrow, spleen, lymph nodes
- supports blood producing cells and immune cells
expand on dense fibrous (Irregular and regular) connective tissue, where its found and what is its function
- dense arrangment of collagen fiber bundles forming straps or sheets
- found in tendons, ligaments, fascia, scar tissue
- function is being flexible, but strong
expand on bone connective tissue, where its found and what is its function
- hard calcified matric arranged in osteons (compact) or network of beams (cancellous)
- found in the skeleton
- functions are support and protection
expand on cartilage connective tissue
- hard but some what flexible gel matrix with embedded chondrocytes
what are the 3 types of cartillage connective tissue
hyaline
fibrocartillage
elastic
where is each type of cartillage connective tissue found and what is its function
- hyaline is founf in the nasal septim, bones, larynx wall and bronchi and its function is firm but flexible support
- fibrocartillage is found in disks between vertebrae and in knee joints and its function is withstanding pressure
- elastic cartillage is found in the external ear and its function is flexible suppoer
expand on blood connective tissue, where is it found and what is its function
- liquid matrix with flowing red/white blood cells
- found in blood cells
- function is transportation
expand on hematopoietic connective tissue, where it is found and what is its function
- liquid matrix with dense arrangement of blood producing cells
- found in red bone marrow
- function if blood cell formation
