connective tissue Flashcards
is the connective tissue the most abundant tissue typr
yes it is
made up of small or big cells
small cells far apart from each other
name some of the connective tissue cells
fibroblasts
macrophages
plasma cells
mast cells
adipocytes
what is a fibroblast cell
present in several tissues
secretory function
what is a macrophage cell
from monocytes
engulf bacteria and cell debris by phagocytosis
what is a plasma cell
develop from B lymphocytes
makes antibodies
what is a mast cell
near blood vessels
part of reaction to injury
release histamine
what is adipocytes cell
fat cell or adipose cell
stores triglycerides (fat)
what is the extracellular matrix
fluid gel or plus protein fibresn
name the three protein fibres
collagen
elastic
reticular
are collagen fibres weak?
no they are very strong and flexible
how does elastic fibres work
smaller stretch and return to original length
how does reticular fibres work
provide support and strength
found in basement membranes and organ support
what are the three loose connective tissue types
areolar
adipose
reticular
what is a areolar tissue
cells embedded in a matrix of glycoproteins and elastin and collagen fibres
what is cartilage
dense network of collagen and elastic fibres embedded in chondroitin sulphate
chrondrocytes
cells
are there blood vessels and nerves in cartilage?
no there isnt
what are the three types of cartilage
hyaline (glassy)
fibrocartilage
elastic
what is hyaline cartilage
fibres not easily visible
what is fibrocartilage
fibres visible
stronger type
what is elastic cartilage
chondrocytes in threadlike network
ear cartilage
name the two liquid connective tissue
blood
lymph
which has more protein blood or lymph
lymph
name the three types of muscular tissue
skeletal muscle tissue
cardiac muscle tissue
smooth muscle tissue
name the two neural tissue types
neurons
neuroglia
what is the neuron tissue
convert stimuli into nerve impulses and conduct them
what is the neuroglia tissue
do not generate nerve impulses.
serve supportive function
where do epithelial cells originate from
stem cells
can muscular tissue replace cells?
yes but slowly
what tissue cells are the worst for replacing
nerve tissue
