What is the structure of the muscular system?

Image
The muscular system is composed of three types of muscle, Skeletal, Cardiac and Smooth. These muscle function to move the skeleton or move materials. There are three types of muscle fibers cardiac, skeletal and smooth. Skeletal muscle is voluntary, multi-nucleated and striated. Cardiac muscle is involuntary, multi-nucleated and striated. While smooth muscle is involuntary, uni-nucleated and non-striated. The typical gross anatomy of a muscle is the large belly and two tendons. The insertion that creates the actual movement and the origin which anchors the muscle in place. Typically muscles move by a process called a contraction which causes the muscle belly to shorten. Muscles work in opposition. The muscle that contracts is called the agonist, while the one that relaxes is called the antagonist. The muscle belly is composed of bundles of muscle fibers called fascicles. It is the muscle fibers which are composed of myofibrils that actually do the contracting because of specialized uni

What function of the spleen

The organ of the spleen is present in almost all vertebrates, including humans and dogs, and it performs several important functions in their bodies. The function of the spleen in general is related to the immune system or blood supply. The spleen removes dark red blood cells, called erythrocytes, from the blood supply and removes, stores and produces lymphocytes of white blood cells. Lymphocytes that are stored produce antibodies and help in removing microbes and other debris from the blood supply. Spleen Characteristics  The spleen is a soft, dark-purple organ found on the upper-left abdomen. Located between the abdomen and diaphragm below the rib cage, the spleen has an average size of 12 cm, a height of 7 cm and 4 cm. Spleen weight and size are somewhat different in life, and can weigh 100-2
