Overview of Human Anatomy Muscles

Human anatomy is the scientific study of your human body's structures. A number of those structures are extremely small and can only be detected and analyzed with the assistance of a microscope. Human anatomy was initially analyzed by detecting the outside of the human body and observation of solder’ wounds and injuries. Later, physicians were allowed to dissect bodies of their dead person to augment their own knowledge. When a body is dissected, its own constructions are cut apart so as to observe their physical attributes and their relationships to one another. Dissection is utilized in medical colleges, anatomy classes, and in pathology labs. To be able to detect structures in people, though, a range of imaging methods have been developed. These methods allow clinicians to visualize structures in the body such as a cancerous tumor along with a fractured bone. Here is a brief overview of human muscle anatomy.

Types of Anatomy

Like most areas, anatomy has areas of specialization. Gross anatomy is the analysis of these larger structures of the human body, those observable without the aid of magnification. Macro- means "large," hence, gross anatomy is also known as macroscopic anatomy.

Microscopic anatomy includes the study of cells and the study of cells. As the technologies of microscopes have advanced, anatomists have now been able to detect smaller and smaller constructions of the human body, from pieces of large structures such as the heart, into the three-dimensional structures of large molecules.

Approaches to Anatomy

Anatomists take two general approaches to the analysis of the human body's constructions: regional and systemic. Regional anatomy is the analysis of the interrelationships of all the constructions in a particular body area, such as the abdomen. In contrast, systemic anatomy is the analysis of these structures that make up a distinct body system--that is a set of structures that operate together to perform an exceptional body function. By way of example, a systemic anatomical analysis of the muscular system could look at all the skeletal muscles of their human body.

There are three kinds of muscle in the human body: Skeletal Muscle, Visceral and cardiac muscles.

Skeletal Muscle

Skeletal muscle is the only voluntary muscle tissue within the human body--it's controlled. Every physical action that an individual consciously performs (e.g. writing, speaking or walking) requires skeletal muscle. The purpose of skeletal muscle would be to contract to move parts of the body closer to the bone that the muscle is attached to. Most skeletal muscles are attached to 2 bones across a joint, or so the muscle works to transfer parts of these bones closer to each other.

Skeletal muscle cells shape if many smaller progenitor cells bulge themselves to form long, straight, multinucleated fibers. Striated like
cardiac muscle, such as skeletal muscle fibers are extremely powerful. Skeletal muscle derives its name from the fact that those muscles always link to the manhood at least one place.

Cardiac Muscle

Located only in the heart, cardiac muscle is responsible for pumping blood through the body. Cardiac muscle tissue cannot be controlled therefore it's an involuntary muscle. Because of its self-stimulation, cardiac muscle is regarded as autorhythmic or intrinsically controlled.

Visceral Muscle

Visceral muscle is located inside of organs such as the stomach, intestines, and blood vessels. The weakest of all muscle cells, visceral fat makes organs contract to move substances through the organ. Because visceral fat is controlled from the part of the brain, it's referred to as involuntary muscle--it cannot be controlled by the mind. The expression "smooth muscle" is frequently utilized to describe visceral fat because it has a very sleek, uniform appearance when seen under a microscope.
