Document Summary
More than 660 muscles in the body of which 430 are voluntary. Range of motion: what the muscle can do (its function) Myo and sarco prefixes for muscle. Can be taken down one more level to the proteins that are contractile (actin and. Triad: tubular network that help facilitate contraction. Transverse tubule (in the middle of cisternae) Sarcoplasmic reticulum: houses special special sacs that contain calcium. Actin and myosin are major muscle proteins. 5% salts and other things such as high energy phosphates, cho, tg, calcium, Extra oxygen carrier/transporter that is present in both cardiac and. Function: take oxygen that hemoglobin(4 oxygen) delivers and bring that oxygen to the mitochondria. Bodies ability to exercise aerobically depends on how we deliver oxygen to mitochondria to make more atp. Sarcomere is basic unit of muscle cell with actin and myosin in special arrangements. Actin is made of troponin and tropomyosin. Contains binding/active site where myosin head binds to.
