Document Summary

Opposing pairs for every movement about a joint you need an opposite muscle to move it back to resting position voluntary muscle; controlled consciously. Has origin and insertion on either side of a joint. Type 1, 11a,11b fast glycolytic oxidative fibers ability to produce energy oxidativley while contracting at a faster freq than. Controls itself with assistance from the nervous and endocrine systems( adrenal gland) Nervous and endocrine produce hormones to increase or decrease heart rate based on whether or not they are being released or removed from the blood stream. Has the ability to contract but have origin and insertions on adjacent myocardial cells. In the walls of blood vessels and internal organs. Muscle fibers are a single cell made up of myofibrils. Can do experiments on single muscle fibers they are very long and thin, able to function (shorten) as a single cell. Endomysium-separates individual fibres, connective tissue surrounding indiv muscle fibers.
