Connective tissue Flashcards
connective tissue makes up every organ of the body —true or false
true
functions of connective tissue
- enclose organs
- connect tissues to one another
3.suport and movement - storage
- cushion/ insulate
- transport
- protect
three major components of extracellular matrix
- ground substance
- proteins fibers
- fluid
protein fibers of extracellular matrix
- collagen
- Reticular
- Elastic
collagen
most common protein in body
strong and flexible and inelastic
rope like
reticular
fill spaces between tissues and organs
form a network
fine collageneous
elastic
returns to original shape after distention or compression
contains molecules of protien elastin that resemble coiled spring and are cross linked
molecules of ground substance of matrix
- hylaranoic acid
- proteoglycans
- adhesive molecules
hylaranoic acid (of ground substances)
pollysaccharide
good lubrication
virtous of eye
proteoglycans (of ground substances)
protien and polysachharide
protein part attaches to hylaranic acid
traps water
adhesive molecules of ground substance
hold proteoglycan aggregates together
suffex is nectin (ie chondronectin in chartalige)
Classifications of connective tissue:
connective tissue proper
loose
dense
Clasification of CT:
Supportive
cartilage and bone
Classification of CT:
fluid
blood and hemoptyic fluid
loose connective tissue properties
fewer fibers, more ground substance
types of loose connective tissue
areolar, adipose, reticular
dense connective tissue properties
more fibers, less ground substance
areolar connective tissue properties
loose packing or “stroma”
lies underneath skin and other tissues
contains all three proteins of extracellular matrix
contains lymphocytes, macrophages, adiposyte, fibroblasts, mast cells
areolar connective tissue structure
cells within fine network of mainly collagen fibers
often merges with dense connective tissue
adipose tissue
mainly adipocytes
yellow adipose tissue
most abundant kind
scant ring of cytoplasm with large lipid droplet
nuclei flattened
white at birth than become yelloe
brown adipose tissue
found in neck, axila and kidneys
nuclei around, multiple adipose polygonal in shape and lots of cytoplasm
adipose function
insulator, protector, and site of energy storage
reticular tissue
forms supersturcutre of lymph and hemopoietic tissue
network of fine reticular fibers and cells
spaces between cells contain white cells and dendrite cells
