Types of Muscular System
The human muscular system consists of various tissues that help in maintaining a stable bodily posture. These include –
Visceral: The muscles are available in organs such as intestines, stomach and blood vessels. Since these smooth muscles get controlled by the nervous system of a body, they are involuntary. The primary function of these tissues is to contract to make things move through an organ.
Cardiac: These tissues are found only in the heart of a human being, and they pump blood throughout the body. They are not in control of the conscious state of mind, and these cells of cardiac tissues are striated. When the brain signals these muscles, they tend to contract, resulting in a movement of the heart. Unlike smooth muscles, cardiac tissues are firm, and they appear to comprise of light and dark stripes when one places them under a light microscope. The colour of bands results due to the positioning of protein fibres within the cells. These cells are in a branched format of X or Y- shape connected firmly at specific joints known as intercalated disks. These disks comprise of projections similar to a finger that ensures to maintain intense bondage between these cells. Both the branched format and disks help cells to prevent high blood pressure throughout life.
Skeletal Muscle: These muscular system parts are only voluntary tissues in the entire human frame. For every action that a person performs requires the functioning of these muscles, such as eating, dancing, jumping, etc. Their contraction allows movement in all parts of a body.
They move to create a pull in the tendons, shortening the tissue length, and nearing bones close to each other. Most of them attach with the bones via durable bands of connective tissue known as tendons.
