types of connective tissue
location: adipose tissue: can be found under the skin and around certain _?_
organs
bone tissue is organized into units called _?_
osteons
the flood has a fluid matrix called?
plasma
blood: _?_ cell fragments that aid in clotting when the endothelial lining has a tear in it
platelets
bone is being continuously broken down and rebulit- responds to use by frowing thicker and stronger... inactively leads to frail brittle bone

lymph: plasma leaves the capillaries and becomes known as intersitial fluid, which bath tissue cells. ISF is distinguished from plasma becasue it lacks larger proteins. Most of the ISF returns to the capillaries. a small amount enters the lymph duct as lymph, which later drains back into the blood. the function of the lymph system is to help maintain homeostasis and alert the immune system to any ifections

this type of loose connective tissue is made primarily of reticular fibers. this is?
reticular connective tissue
we will see many dark cells with dark _?_ fibers scattered throughout
reticular fibers
what is the function of dense regular connective tissue?
secure bone during movement
areolar connective tissue: function: the arolar tissue forms a layer that _?_ the skin from the underlying structures. this serves to absorb multidirectional shock and permits without damage
seperates
location: reticular connective tissue: the s_____, L____, L____N____, and B____M_____
spleen liver lymph nodes bone marrow
this tissue contains mainly adipocytes which have only a small area of cytoplasm and a large fat droplet?
adipose tissue
drct: _?_ a flat sheet like structure that attches muscle to bon or bone to bone
aponerousis
this is the most widley distributed of all the connective tissues?
areolar
name the three types of loose connective tissue

vascular connective tissue: what are the two vascular connective tissues?
blood and lymph
adipose tissue: _?_ fat is found in infants and is different than white fat like adults have. brown fat has numerous mitochondria. the adipocytes can be stimulated by the nervous system to break down their lipis contents which leads to an increase in _?_?_
brown body temp
the location of dense irregular connective tissue is they are found in _?_ and also forms a layer around cartilage (_?_) and around bone (_?_)
joints perichondrium periosteum
_?_ (open space) in the matirx houses osteocytes - bone cells
lacunae
chondorcytes are found in the matrix spaces called ?
lacunae

leukocytes
drct: _?_ attaches bone to bone
ligaments
_?_?_?_ packing material; cushion and stabalize; fill spaces between organs; surround and support other tissues
loose connective tissue
what is the location of elastic tissue?
lungs and arteries
adipose tissue has very little _?_ the cells are packed closely together and looks like chicken wire
matrix
areolar connective tissue: location: it is located between epithelial tissue and _?_ tissue. it acts similar to glue.. it holds the two structures together
muscle
can diffusion occur between this matrix?
no
_?_ cytoplasmic extensions of osteocytes that radiate in toward the havarsian canal
canaliculi
this is an avascular and aneural part of connective tissue? (except for the outer layer called the perichondrium)
cartilage
what is the only cell present in cartilage?
chondrocytes
_?_?_?_ are dense protein fibers
dense conective tissues
collagen fibers are not in an arranged pattern. the fibers are scattered in various directions.. this is an example of what type of dense tissue?
dense irregular
the scattered unordered fashion that the fibers are arranged in actually adds to their strength when they are being pulled in difference directions this function is the function of what type of dense connective tissue?
dense irregular connective tissue
this dense tissue is not nice, neat or orderly?
