|
tunics |
layers or circumferential tissue forming tubular organs surrounding a central space |
|
|
lumen |
central space of a tubular organ |
|
|
tunica mucosa |
-innermost layer around lumen -3 sublayers -epithelium next to lumen -lamina propria of C.T. that supplies nutrients -muscularis muscosa (smooth muscle) |
|
|
tunica submucosa |
layer of C.T. contianing fat, small blood vessels, and nerves -may also have glands depending on the organ |
|
|
tunica muscularis |
layer of two or three layers of smooth muscle propels substances through the organ |
|
|
tunica adventitia/serosa |
-outermost layer -C.T. -adventitia covers organs without an epithelial membrane -serosa has additional epithelial membrane continuous with the lining of the body cavity |
|
|
tunica intima |
-inner tunic of blood vessels -layer of simple squamous epithelium (endtothelium) -thin layer of supporting C.T. -smooth non-stick surface for blood |
|
|
tunica media |
-middle tunic of blood vessels -smooth muscle -well-developed in arteries -controls size of lumen -separated from other tunics by elastic membranes |
|
|
tunica adventitia |
-outer tunic of blood vessels -C.T. -forms a passageway for the blood vessel between other structures |
|
|
atrium |
chamber of heart that recieves blood |
|
|
ventricle |
chamber of heart that pumps and distributes blood |
|
|
endocardium |
-innermost layer of heart -thin layer of C.T. and endothelium |
|
|
myocardium |
-middle layer of heart -thick layer of cardiac muscle |
|
|
epicardium |
-outer layer of heart -layer of C.T. covered by simple squamous epithelium -contains coronary blood vessels and fat |
