Document Summary
Skeletal move bones of the skeleton: striated: alternating light and dark bands under microscope, voluntary somatic division of nervous system. Cardiac only the heart: striated, involuntary autonomic division and hormones released by endocrine glands, autorhythmicity: built-in rhythm, pacemaker that initiates each contraction. Smooth muscle tissue located in the walls of hollow internal structures e. g. blood vessels, airways and most organs in the abdominopelvic cavity: non striated, involuntary - autonomic division and hormones released by endocrine glands. Some smooth muscle tissue such as the muscles that propel food through your. Muscle fibers aka muscle cell hundreds to thousands of cells in their elongated shapes make up the skeletal muscle. Skeletal muscle consists of individual muscle fibers (cells) bundled into fascicles and surrounded by three connective tissue layers that are extensions of the fascia. Subcutaneous layer or hypodermis separates muscle from skin. Composed of areolar connective tissue and adipose tissue.
