Connective Tissue Flashcards
precursor stem cells
undifferentiated mesenchyme, hematopoietic
what, generally, is connective tissue
chicken noodle soup. cells, fibers, amorphous ground substance
3 types of connective tissue
- loose ct
- dense ct
- Special ct
2 types of special ct
- adipose (unilocular and multilocular)
2. reticular
2 types of regularly arranged dense ct
collagenous tendons and ligaments
elastic ligaments
reticular ct
type 3 collagen
delicate fibers, NOT bundles
support and bind cells, lots of space between fibers
integral part of basement membrane
type I collagen
ligaments, tendons
regular or irregularly arranged bundles and layers
dense ct
high tensile strength, do not stretch, hard to break
type 3 collagen
reticular ct
type 4 collagen
basal laminae
does not assemble into fibrils
supportive, open network, 2d scaffold
mast cell
resident ct. granules; histamine, heparin, proteases
loose ct, by blood vessels
macrophages
look chunky or brothy, bubbly (cytoplasmic vacuoles)
resident OR immigrant; follow chemotactic stimuli
phagocytic; contain lots lysosomes and phagosomes
eosinophils
immigrants; circulate in blood less in tissue
large granules in cytoplasm
effective neurotoxic proteins against PARASITES
plasma cells
immigrant; from B lymphocytes
numerous in lymph tissue, inflammation
have clock face
produce antibodies (tag for opsonization)
resident cells
mast cells
immigrant cells
eosinophils and plasma cells
