- how many skeletal muscles
- about 980
- two jobs of the skeletal system
-
movement, controlled by tendons
body heat [shivering] - red fibers
- slow twitch, areobic metabolism... slow atp production
- write fibers
- powerful short twitch, quick atp production, more likely to accumalate latic acid
- actin
- small protein fillaments
- myosin
- large protein fillaments
- myofibrills
- bundles of fillaments that run from one end of the cell to another
- myogenic
- stimulates its own contractions
- exoskeleton
- outside skeleton, supports less weight. ex arthropods, shellfish and insects
- endoeksleton
- bones, cartilidge
- hydrostatic
- jelly fish
- Haematopoiesis
- production of blood cells in the bone
- ossify
- mineralize
- calcification
- deposit of calcium in the bones
