- 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
