platelet cells found where | gastrointestional and resp. tract, lymph nodes, salivary glands, spleen, red bone marrow |
extracellular matrix consists of two major components | ground substance and fibers |
component of connective tissue b/t cells and fibers | ground substance |
help transport water to make ground sub. more jelly like | GAG |
viscous slippery sub. that binds cells together, lubes joints and helps maintain shape of eyeball | hyalurnic acid |
pro. support and adhesiveness in cartilage, skin, bone and blood vessels | condratin sulfate |
resp. for linking components of the ground substance to one another and to surfaces of cells | adhesive proteins |
main adhesion protein of connective tissue- binds to collagen fibers and ground substances | fibronectin |
resist pulling forces, but are not stiff which allows felx. | collagen fibers |
collagen fibers found? | bone cartilage tendons and ligaments |
elastic fiber found? | skin, bv, lung tissue |
consist of collagen arranged in fine bundles with coating of glycoprotein | reticular fiber |
produced by fibroblasts | reticular fibers |
reticular fibers found? | soft spots on organs; spleen, lymph nodes |
contains numerous, thicker, dense fibers, but fewer cells then loose connective | dense connective tissue |
bundles of collagen fibers are regularly arranged in parallel patterns that provide tissue with great strengh. withstands pulling along axis of fibers | dense regular connective |
dense reg. connective found where? | tendons and ligaments |
dense irregular found? | dermis of skin, fibrous pericardium around heart, perichondrium and periosteum |
resilience in cartilage is due to? | condrotin sulfate |
covering of dense irregular tissue is called? | perichondrium |
the outer layer of pericondrium consists of? | collagen fibers, BV, and fibroblats |
inner layer of pericondrium | cells in cartilage growth |
hyaline cartilage contains ______ shell as ground substance | resilient |
in hyaline cart. condrocytes are found in where? | lacunae |
concentric rings of extracellular matrix that consists of mineral salts giving the bone its hardness responsible for compact nature | lamellae |
small spaces between lamellae that contain mature bond cells called ostocytes | lacunae |
project from lacunae, networks of mintue canals containing process of ostocytes | canaliculi |
contains blood vessels and nerves | central canal |
spongy bone consists of columns of bone called | trabeculae |
space between trabeculae is filled with | red bone marrow |
layer of serous membrane attached to and lining cavity wall | parietal layer |
layer that covers and adheres to organs within the cavity | visceral |
_____ ______ secretes serous fluid | simple squamous |
covers entire surface of body; epidermis/dermis | cutaneous membrane |
synovial membrna are composed of | synoviocytes |
_____ brance off of the cell body and are major recieving/ input porting of cell | dendrites |
do not generate or conduct nerve impulses | neuroglia |
condrocytes divide and form new matrix; increase in length | interstital growth (childhood and adolence) |
condroblasts secrete matrix onto surface; increase in width | appositional growth |
bone consisits of a matrix containing mineral salts and collagenous fibers and cells called | ostocytes |
reticular fibers composed of | collagen and glycoprotein |
3 types of loose connective tissue | areolar, adipose, reticular |
in areolar connective name 3 types of cells | fibroblats, plasma cells, macrophages and mast cells |
helps bind together the cells of smooth muscle | reticular connective tiusse |
consists of a dense network of collagen fibers and elastic fibers embedded in condroitin sulfate | cartilage |
lacks pericondrium | fibrocartilage |
pericondrium is present | elastic cartilage |
maintains the shape of certian organs | elastic cartilage |
in compact bone the basic unit of structure is | osteon (Haversain system) |
im lamellae what gives it its hardness | calcium and phosphate |
are flat sheets of pliable tissue that cover or line a part of the body | membranes |
line joints and contain only connective tissue | snovial membranes |
consists of an epitheial layer and an underlying connective tissue layer(lamina propia) | epithelial membranes |
lines cavities that open to exterior | muscous; mouth, stomach, vagina, urethra, respirtatory |
connective tissue later of a mucous membrane is called | lamina propria |
nerve cells | neurons |
protective and supporting cells | neuroglia |
neurons and muscle fibers are | excitable cells; they show electrical excitablity |
replaced by the divison of stem cells or by divison of undifferentiated cells | epithelial |
have a poor capactiy for renewal | muscle cells |
poorest capacity for renewal | nervous tissue |
process of scar formation | fibrosis |
