MEMBRANES
|
portion of your body (portions of tissues) that consist of epithelial and connective tissue
|
|
Serous Membrane
|
Lines the thoracic and abdominal cavities
- simple squamous cells produce the serous fluid |
|
Mucus Membranes
|
lines all canals that are open to the outside.
-goblet cells produce the mucus |
|
Skeletal muscle tissue (description of cells)
|
- cylindrical
- multi-nucleated - striated - not mitotic - very long (several inches) - made up of 300+ cells |
|
Skeletal muscle tissue (where is it found?)
|
-found in the body wall and operates lips, urethra, and anus
-found around the skeleton -outside the bladder and suroounding the anal canal and urethra (allows decision for bathroom) |
|
Skeletal muscle tissue (purpose)
|
- muscle that moves the skeleton
- for volutary muscle movement |
|
Cardiac Muscle tissue (general)
|
-wraps around the heart
-heart beast 70 times a minute, 200 while workign out -has many reserves |
|
Cardiac Muscle tissue (cells)
|
-Not mitotic
-small and mostly single nucleated -striped/striated -has short branched cells |
|
Cardiac Muscle tissue (short branched cells)
|
-allows for impulses to go around dead cells
- allows impulses to continue to destination and by-pass any blockage |
|
Cardiac Muscle tissue (intercalated disks)
|
-found b/t sequential cardiac muscle cells
-consists of the membranes of the cells along with the desmosomes and gap junctions |
|
Cardiac Muscle tissue (heat production)
|
helps to keep our body's temperature at 98.6 due to constant use of the muscles
|
|
Cardiac Muscle tissue (silent heart attacks)
|
-not big enough to have the symptoms of normal heart attacks
- conists of little blocks of the smaller portions of the coronal vessels by dead cells that were starved. |
|
Smooth muscle tissue (cells)
|
-small cells that are elongated (spindle shaped) and have a single nucleus
- Mitotic |
|
Smooth muscle tissue (Where is it found?)
|
-Found in walls of canals/vessels that transport
Digestive- starts 1/3 of the way down esophagus to the end -found in major blood vessels to regulate blood pressure -found in ureters to transport urine and waste from kidneys to bladder -found deep in lungs -found anywhere things are moved/propelled through |
|
Smooth muscle tissue (heat production)
|
-muscles are operating 24/7
-cells wear out adn need to be replaced -1000 chemical reactions are going on right now -optinum temp. for reactions is 98.6 so muscles contractiosn keep this temp up. |
|
Nervous Tissue (neurons)
|
-Not mitotic
-cells are specialized to carry an electrical current called an impulse |
|
Nervous tissue (glial cells)
|
-support, nurture, and protect neurons
|
