Document Summary
May also be stimulated involuntary (ie shivering) Muscle fibers are a single cell made up of myofibrils. 3 types of fibers: slow oxidative fibers (so) Metabolic profile and contractile characteristics: fast oxidative glycolytic fibers (fog) Fast twitch a (fta) or type lla. Faster contraction/relaxation times, provide us with aerobic atp (oxidative and glycolytic phosphorylation: fast glycolytic fibers (fg) Fast twitch b (ftb) or type llb. Type llx fibers are actually more commonly found in humans, where as type llb fibers are more commonly found in other mammals. Type llb fibers have very limited aerobic capacity. Type llx fibers have some oxidative (aerobic) capacity. Fastest contracting fibers, atp-pcr or anaerobic glycolysis. Controls itself with assistance from the nervous and endocrine system (adrenal gland ep and nor ep) No specific origin and insertion attachments to adjacent myocites. Connective tissue enables transfer of force within muscle when length of. Located in the walls of blood vessels and internal organs.
