Terms in this set (46)

Pads between vertebrae that are shock absorbers
cushioning and support
matrix contains primarily collagenous fibers with a "cushioning gel"

how to identify fibrocartilage

blue water with holes in it; fewer cells with more space btwn them

simple squamous

single layer of flat cells
located in the alveolar sacs (lungs) and lines blood vessels (capillaries)
diffusion and protection

how to identify simple squamous

thick squiggly membrane

simple cuboidal

single layer of cube shaped cells
secretion and protection
found in glands, kidneys, ducts of glands
in ring or line formation
secrete hormones, steroids, enzymes
organelles with these cells have a highly developed ER

how to identify simple cuboidal

either a line of square cells
or a donut with sprinkles

simple columnar

Single layer of tall cells
absorption, protection, secretion (mucus)
found in the walls of the intestines

how to identify simple columnar

long columns
blank spaces (goblet cells)

pseudostratified columnar (ciliated)

filtering, cleaning, secretion (mucus), protection
trachea, bronchial tubes
cilia beats in rhythm to move mucus against gravity

how to identify ciliated columnar

looks like simple columnar but with hair like Mr Roberts

Transitionalelasticity, stretching urinary bladder, urethra/ureters withstand stretching and compressionhow to identify transitionalbordersstratified squamous keratinizedskin protectionstratified squamous nonkeratinizednote the lack of top layer protection mouth and esophagushow to identify stratified squamous and the difference between the twoK- 3 layers, even a tiny one on top NK- nucleus, looks like fish swimmingBonebody form, protection, hematopoiesis skeleton matrix has collagen fibers and calcium salts embedded in the fibers giving bone its hardness and strength, but also flexibility 2 types; spongy and compacthow to identify bonecircles all over little dots in line inside the big circle kinda a reddish brown color i think he said it was the only brown stainhyaline cartilagefirm, flexible support nasal septum (tip of nose), costal cartilage (ribs), bone ends, sternumhow to identify hyaline cartilagemini mike wazowskis in it lots of space btwn cellselastic cartilagecartilage with abundant elastin fibers; more flexible than hyaline cartilage flexible support ear, eustachian tube (connects ear and throat)how to tell elastic cartilagedark purple cells very close together less space, more cellsdense fibrous regulartendons and ligaments strong af, non-elastic connection lots of collagen fibers which gives it strengthdense fibrous irregulartough layer, connects skin to body dermis of the skin (under the skin)how to tell DF regular and irregular and how to tell them apartDFR- dark pink waves with dots in lines; uniform DFIR- pink and white swirl; looks like the top of strawberry cheesecakeAreolarhighway for white blood cells body defense, connection under the dermis, connection to other tissues forms cob webby tissue btwn organs liquid in matrix and provides a conduit for phagocytic cells to move to injured/infected areas contains a lot of different fibers but mainly elastinhow to identify areolardark strands all over lots of space between cells thick line: cartilage thin lines: elastinadiposeenergy storage, insulation, padding under trunk (chest/belly area) skin, surrounding organs cells look empty cuz of how the slide was madehow to identify adiposelooks like big white circles will have a little bit of dark spots looks like cobblestone similar to lung cells so be carefulreticularfiltering lymph, immunity lymph nodes, spleen, bone marrow where the tissue acts as filters to clean the lymph martix is plasma cant find a good picture sorryhow to identify reticularlimited amount of fibers small cells with lots of dark spots kinda looks like raisins i cant find a good pick but it's kinda similar to elastic cartilageBloodcardiovascular system transportation has a liquid matrix to allow many things (like gases, nutrients, wastes, hormones, enzymes, etc) to be dissolved and transported when it clots it has a similar matrix structure that is found in the other connective tissueshow to identify bloodcircles all over has a few white blood cells with multiple dark spotsskeletal muscle (striated)conscious movement (voluntry contractions attached to bone big nucleuscardiac musclefound in heart only contractions allow the heart to pump blood through the circulatory system course lookingsmooth musclefound in walls hollow organs (stomach, esophagus, etc) move materials through hollow organs control the flow of materials through hollow organshow to tell the difference between the 3 muscle typesSk- looks regular with little dots between the rectangles C- corser with bigger dots; looks rough Sm- has a wave look; long flat nucleusNervebrain, spinal cord, throughout the body communication, connection, control, coordination control of body functionshow to identify nervebig triangle with long strings coming offlung cell simple squamousmore of an irregular shape similar to adipose so don't get them confused has cells between the white spotsspermpretty easy to identify only cell in the human body with a flagellaovumbig circle also pretty easy to identify might have sperm around the edgeepithelial tissuescovering issues main function is protectionconnective tissuesvaried functions but mostly for protection, connection, and support use and function is dependent on the matrixmatrixwhat's between the cellsmuscle tissueconsists of primarily 2 protein fibers (actin and myosin) which have the capability to contract when working togethernervous tissuesfound in brain and spinal cord also extent into the peripheral areas neurons in the peripheral areas are gathered in areas called plexus and ganglia function is conductivity and connectivity control of body functions
