epithelian tissue derrived from ___ | all three (ecto, meso & endo derms) |
this tissue cover cells bc cells are in contact | epithelial tissue |
this forms glands when cells sink under the surface | epithelial |
these are formed when cells sink under the surface | glands |
this tissue has an electrical charge | nerve tissue |
this tissue stores energy at fat | connective |
this tissue provide immunity to disease | connective |
this tissue has material between cells and supports and binds structures together | connective |
in this tissue cells shorten in legth producing movement | muscle |
this tissue detects changes inside and outside of the body | nerve |
these junctions are fused with a strip of proteins | tight junctions |
dense layer of proteins inside the cell membrane | plaque |
in these junctions microfilaments edtend INTO the cytoplasm | adherens junctions |
in these junctions integral membrane proteins connect to membrames of other cells | adherens |
these junctions resist separation and cell disruption | desmosomes |
these cell junctions intracellulare intermediate filaments CROSS cytoplasm of cell | desmosomes |
these junctions are cellulare support of cardiac miscle | desmosomes |
these junctions connect cells to extracellular material eg masement membrane | hemidesmosomes |
these junctions are crossed by protein channels called connexons forming fluid filled tunnels | gap juntions |
these proteins channels cross gap junctions forming flud filled tunnels | connexons |
in this junction cells communicate w ion & small molecules (spreading nerve impulses) | gap junction |
the basal lamina is made up of __ | collagen fibers |
the basal lamina is made up of thsee cells | epithelial |
_____ lines blood vessels and body caveties | simple squamous epithelium |
this type of epithelium controlls diffusion | simple squamous epithelium |
this lines the tubes of the kidney | simple cuboidal epithelum |
this epithelium controls absorbtion and secretion | simple cuboidal |
unicellular glands in non-ciliated simple columnar | goblet cells that secrete mucus |
this epithelium has microvili which are used for ____ | nonciliated simple columnar & absorbtion in gi tract |
in the epithelum mucus from goblet cells is moved along by cilia | ciliated cimple columnar epithelum |
this epithelum is found in the respiratory system and uterine tubes | ciliated simple olumnar |
keratinized stratified squamous are found in the ____ | skin |
nonkeratinized stratified squamous are found in the ___ | mouth & vagina |
these are rare epithelium only found in sweat gland ducts and makle uerethra | stratified cuboidal & stratified columnar |
this epithelium lines hollow organs that expand from within eg uniary bladder & is multilayered | transitional epithelium |
thees single layer epithelium lines respiratory systems, male eurthra and have nuclei at varying depths | pseudostratified columnar |
these glands secrete onto a free surface | exocrine |
these glands secrete hormones into the bloodsream | endocrine glands |
unicellular glands: an example of them is | goblet cells |
compound multicellular glands are ___ | branched |
simple multicellular are ___ | unbranched |
most glands use this type of secretion in which cells release their products by exocytosis (eg salivia, sweat) | merocrine |
oil glands use this type of sercretion wher the whole cells dies and releaasese their products | holocrine |
these cell types retain ability to divide and produce | blasts type |
mature cells that can not divide or produce matrix | cytes |
cells that decelop from monocytes | macropages |
thse cells develop from B lymphocytes | plasma cells |
mast cells produce ____ | histomine |
this is a jellylike substance providing support for connective tissue | condroitin sulfate |
thes proteins bind collagen fibers to ground substance | adhesion |
this ct is thin branched that form framwork of organs formed from the protein collagen | recticular |
thi sgives rise to all other types of connective tissue (embryonic ct) | mesenchyme |
star shaped cells in jelly like ground substance found only in umbilical cord | muscous ct |
this typoe of loose ct is irregular | areolar ct |
this ct has fibroblasts, collagen fibers, and elastic fibers, | areolar ct |

this ct is a netowrk of fibers and cells that produce framwork of organ holds organs together | reticular ct |
in dense ct more fibers ar present but fewer___ | cells |
dense collagen fibers in parallel bundles with fibroblasts | dense regular connective tissue |
this type of ct forms tendons | dense regular ct |
dct taht forms whites of eyeballs, dermis of skin and resists tension from any direction | dense irregular ct |
