Section 1

Question Answer
Cells are surrounded byextensive extracellular matric
extracellular matrix is composed ofprotein fibers and ground substance
Connective tissue's vascularityvaries greatly between types
Connective tissue proper composed of Loose and Dense
Loose connective Tissueareolar, adipose, reticular
Dense Connective Tissueirregular, regular, elestic
cartiledge and bone are supporting connective tissue
Supporting connective tissue are comprised ofcartitledge and bone
Blood and Lymph areFluid connective tissue
Fluid connective tissue are comprised of Blood and Lymph

Section 2

Question Answer
Areolar, adipose and reticularLoose connective Tissue
regular, irregular and elasticDense connective tissue
protein fibers and ground substancewhat extracellular matrix is comprised of
cartidge and bonesupporting connective tissue
blood and lymphfluid connective tissue

Section 3

Question Answer
Fibroblastsproduce fibers of extracellular matrix
adipocytesContain single, enormous lipid droplet
Mesenchymal cellsstem cells that respond to injury by producing fibroblasts and othe connective tissue
Macrophagesoriginate as WBC; attached to fibers, or actively move about; phagocytize pathogens and other cell debris
mast cellsrelease heparin and histamine
LymphocytesWBC; develop into antibody producing plasma cells in response to a specific pathogen
melanocytessynthesis & store brown pigment melanin

Section 4

Question Answer
most common type of fixed cellsfibroblasts
fat cellsadipocytes
stem cells that respond to injurymesenchymal cells
fixed or free and originate as WBC's and phagocytize pathogens and cell debrismacrophages
located near blood vessels; releases anticoagulant and increases cell permeabilitymast cells
White blood CellsLymphocytes
abundant in CT of eye and dermis of skin. Synthesize and store melaninmelanocytes

Section 5

Question Answer
Produced by fibroblasts of CT properCollagen, elastic and reticular fibers
collagen fiber are composed ofprotein collagen
collagen fiber are arrangedgrouped in long, parallel bundles
collagen fiber providetensile strength
Elastic fibers are composed ofprotein elastin
Elastic fibers are arrangedbranched, forming complex networks
Elastic fibers provideelasticity
Reticular fibers are comprised ofthin collagen fibers
reticular fibers are arrangedhighly branched
Reticular fibers providesupporting frameworks for internal organs

Section 6

Question Answer
Loose connective tissue includeAreolar, adipose and reticular CT
Ground substance of Loose CT containsa loose network of collagen and elastic fibers
Areolar tissuebinds skin to deeper structures, fills spaces b/t muscles, underlies most epithelia
Which loose CT is highly vascular?Areolar Tissue
Adipose TissueCushions joints and organs, provides thermal isulation, stores energy
Which loose connective tissue is another term for fat?Adipose Tissue
Reticular Connective tissuefibers form a supporting framework for internal organs (liver, spleen, lymph nodes)

Section 7

Question Answer
Dense Connective Tissue includesregular, irregular and Elastic tissue
Ground substance of Dense CT contains dense network of collagen or elastic fibers
Dense Regular CT consist mainly of ______ fibers.closely packed collagen fibers
Dense Regular and Irregular CT also contain _____ fibers.fibroblasts and elastic fibers
Dense regular CT formsligaments and tendons
Which Dense CT is poorly Vascularized?dense regular CT
Irregular CT consists mostly of ___randomly organized collagen fibers


Question Answer
Which Dense CT is well Vascularized?Irregular CT
Regular CT has ____ tensile strength in ______ direction(s)great, a single
Irregular CT has ____ tensile strength in ______ direction(s)considerable, many
irregular CT formsdermis of the skin
Elastic tissue consists mainly of Elastic fibers in parallel strands or branching networks
Elastic tissue also contain _____ fibersfibroblasts and collagen fibers
Elastic tissue formsligaments nuchae and ligamenta flava of the vertebra column
which tissue DCT is present in walls of the larger arteries?Elastic tissue

Section 8

Question Answer
Cartiledge includes these three sub typesHyaline, Elastic, and Fibrocartilage
Hyaline Cartilagefine collagen fibers in extracellular matrix
Hyaline Cartiage formsEmbroyonic skeleton, connects ribs to sternum, covers joint surfaces, supports nose and respiratory passages
Elastic cartilagedense network of elastic fibers in extracellular matrix
Elastic Cartilage supportsexternal ears and epiglottis
Fibrocartilagedense network of collagen fibers in extracellular matrix
fibrocartilage formsintervertebral disks and symphasis pubis
Cartilage is helpful forshock apsorption, placeholder for bones and lubrication
Flexability and support is best represented by with Cartilage?Hyaline
pierced ears?Elastic cartilage
Spine and childbirth?Fibrocartilage

Section 9

Question Answer
Bone is a _____ CTSupporting
bone providessupport and protection
bone provides attachment formuscles
Blood containsRed Marrow
Bone storesCalcium and phosphorus
osteosytes arecells
Lacunea arespaces
Blood is ____ _____Highly Vascular
Osteon are ____ of compact bonecylinder-shaped structural unit
Osteon are composed of ____ around the _____ containing _____.concentric lamellae, central canal, blood vessels
concentric lamellaelayers of bone
osteocytes are connected by cytoplasmic processes lying within canaliculi of extracellular matrix
nutrients of osteocytes diffuse throughcytosol

Section 10

Question Answer
Plasma is liquid
except during blood clotting, ____lacks fibersBlood
Formed elements produced in red bone marrow includeRBC, WBC, Platelets and Lymph
This transports O2 and helps transport CO2Red blood cells
This fights infectionWhite blood cells
this plays key role in blood clottingPlatelets
WBC suspended in extracellular fluidLymph
Lymphblood plasma filtered through capillary walls
blood is considered a Fluid Connective Tissue
