There are three types of muscle tissue in the human body: skeletal, smooth, and cardiac. Others allow us to express our emotions through facial expressions. While skeletal muscle is controlled voluntarily by the somatic nervous system, smooth and cardiac muscle tissues are controlled involuntarily by the autonomic nervous system. Pick up the cellular 3D models and examine the nuclei, myofibrils, mitochondria and more to understand how the intracellular components enable each muscle cell to perform the functions characteristic for that muscle tissue.

Download Free Pearson Anatomy Physiology Lab Manual Answer Key Free For muscle cell contraction, the initial sources of energy (ATP) are intracellular ATP (4-6 seconds), creatine phosphate (another 10-15 seconds), aerobic metabolism (fatty acids -rest or light exertion, and glucose), and anaerobic metabolism (1 to 2 minutes). labster muscle tissue overview quizlet - playtcubed.com There are two types of bone tissue: compact and spongy.The names imply that the two types differ in density, or how tightly the tissue is packed together. the cells are capable of mitotic division for repair, unlike skeltal and cardiac myofibers. The characteristics that allow these functions are contractility which is unique to muscle and excitability which is responding to sitmuli by generating an action potential. How do smooth muscle cells differ from striated cells with respect to the role of T-tubules, tropomyosin, and attachment of thin fibers?
