Connective Tissue Flashcards
Characteristis of connective tissue
most common more matrix than cells fibers run through matrix holds structure and support different vascularity
strongest protiens body makes
collagen or white fibers
vitamin c and mineral copper are needed to form these
collagen fibers
tiny versions of collagen fibers
reticular fibers
do what collagen cannont, return to original posision once pulled or stretched
elastic fibers or yellow fibers
loose connective designed to store fat
adipose tissure
beneith skinm aroundjoints, padding kidneys, etc.
adipose tissue
like within lacunae and arranged in circles
osteocytes
where are osteocytes located
bone tissue
rigid connective tissue , provides framework
cartilage
lacks vascular system and heals slow
cartilage
cells that create tissue
fibroblast
thick white fibers , very strong, made by fibroblast through protein synthesis
collagen fibers
the more room in the matrix= more blood vessels found
capillary
type of WBC, commonly count it CT. , releases histamine or heparine
mast call
neutrophil or monocyte
white blood cell
small collagen fibers, secreted by fibroblasts
reticlular fibers
fluid filled space between cells
matrix or IT
very vascular, rule breaker- has cellularity
adipose tissue
makes upframework of hallow organs(spleen,liver,lymph noder)
loose reticular
very vascular to filter lymph
loose reticular
packed with fibers- not much room for blood vessels, slow healing
dense irregular
stregnth in all directions
dense irregualr
periosteum(around bone) perichoduim (around cartilage) permysium and epimysium(around m+) blood vessels, and GI tract
dense irregular
not many blood vessels- slow healer, all fibers in one direction- strength in that direction
dense regular
tendons, ligaments, fibrousmembranes
dense regular
mainly found under transitional epithelium, wall of resipratory pathways and wall of blood vessels
dense elastic
can form elastic ligaments that allow movement of vertebar
dense elastic
matrix is firm because of proteoglycans
cartilage connective tissue
avascular-discourages blood vessel formation
cartilage connective tissue
must live in pools, bc firmmatrix
cells(chondrocytes)
what are the pools cells live in
lacunae
no room for nerves
cartilage connective tissue
surrounds the cartilage
perichondrium
toughest cartilage, white loaded with collagen fibers
hyaline cartilage
wear and tear- ends of joints, nose, trachea, connecting ribs to sternum
hyaline cartilage
alternate rows of cells, matrix, and fibers create tissues that absorb a lot of forces
fibrocartilage
meniscus,inter-vertebral discs, pubic symphysis
fibrocartilage
strong like hyaline but elastic fibers allow it to return to original shape after bending
elastic cartilage
external ears, epiglottis
elastic cartilage
gel like matrix of cartilage has c++ salts added to make matrix harder
bone(osseus) connective tissue
2 types- compact and spongy
Bone tissue
very vascular-canals contain blood vessels run through matrix to give nutrientdelivering(compact) or hourse red marrow(spongy)
bone tissue
large nerve supply, high amount of collagen fibers- stregnth
bone tissue
osteoblast(build), osteoclasts(break down), osteocytes(cells)
bone tissue
ring of cells
lamella
bone cell
osteocyte
lake where cell lives
lacunae
tiny canals - carry nutrients form one lacunae to another
conaliculi
carries blood vessels and nerves to lamella belonging to that group
central canal
travel at right angles, connect osteons, periosteum, and medulary cavity
volkmanns canal
what is matrix fluid know as in blood
plasma
fibers are used for what in blood
bloodclotting
more matrix than cells
blood
cells originate from red bone marrow by
hemocytoblasts
RBC
erythrocytes
WBC
lemkocytes
Platelets
Thrombocytes
