Document Summary

Overview of muscular tissue: myology study of muscle tissue, muscular tissue accounts for 40-50% of total body mass, most of the work generated by the body.

Several hormones and neurotransmitters adjust the heart rate by speeding up or slowing down the hea(cid:396)t"s natural pacemaker. Intercalated discs (only found in cardiac muscle: smooth located in walls of blood vessels and muscles of the digestive tract (most organs of the abdomen), controlled by automatic nervous system, not striated, smooth. Involuntary: *these types differ from one another in their anatomy, how they are controlled. Stabilizing body positions (body position: posture, locking our knees, stabilizing joints. Storing and moving substances: move blood, lymph, urine, hormones, air, food etc.
