APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Smooth muscle differs from skeletal muscle in a variety of ways, perhaps the most important being its ability to be contracted and controlled involuntarily.

Detailed explanation-2: -Muscle tissue (or muscular tissue) is soft tissue that makes up the different types of muscles in most animals, and give the ability of muscles to contract. Muscle tissue is formed during embryonic development, in a process known as myogenesis.

Detailed explanation-3: -Skeletal muscles attach to and move bones by contracting and relaxing in response to voluntary messages from the nervous system. Skeletal muscle tissue is composed of long cells called muscle fibers that have a striated appearance.

Detailed explanation-4: -Smooth muscle can tense and relax but has greater elastic properties than striated muscle. This is important in organ systems like the urinary bladder where contractile tone must be preserved. Actin and myosin form continuous chains within the smooth muscle cell which are anchored at the dense bodies.

Detailed explanation-5: -‌Your muscles contain fibers called myosin. Depending on how you need to use your muscles, the myosin fibers either tighten up and shorten or loosen up and stretch out. Myosin is also responsible for muscle contractions like your heartbeat that happens at regular intervals.
