ZM1003-1 Human Skeleton Attached Muscle Attachment Point Shading Model Human Muscle Classification


skeletal muscle


is the type of muscle that can be seen and felt. When bodybuilders increase muscle strength through exercise, they exercise skeletal muscles. Skeletal muscles attach to bones and come in pairs: one muscle moves the bone in one direction, and the other moves the bone in the opposite direction. These muscles usually contract at will, meaning that when you want to contract them, the nervous system tells them to do so. Skeletal muscles can do short single contractions (twitch) or long-term sustained contractions (tetanus).


Human skeletal muscle can be divided into two types of fibers: red muscle and white muscle. Red muscle fibers rely on hemoglobin to continuously supply oxygen to exercise, contract and stretch for longer periods of time, allowing us to carry out our daily behavioral activities. The white muscle fibers (mostly in emergency situations) rely on rapid internal chemical reactions to rapidly expand and contract, which is characterized by persistence and short reaction time, and its reaction time is one-fourth of that of red muscle fibers.


smooth muscle


Found in the digestive system, blood vessels, bladder, respiratory tract, and the uterus of women. Smooth muscles are able to tighten and maintain tension for long periods of time. The muscles do not contract at will, meaning that the nervous system automatically controls them without human thought. For example, the muscles in the stomach and intestines perform tasks every day, but people generally don't notice it.


myocardium


Existing only in the heart, its greatest characteristics are endurance and sturdiness. It can stretch with limited stretch like smooth muscle or contract with force like skeletal muscle. It's just a twitching muscle and doesn't contract at will. The heart muscle has a fixed rhythm of contraction to generate the heartbeat. The pacemaker cells of normal people are normal, and the law of myocardial contraction is certain. If the pacemaker cells are abnormal, the law of myocardial contraction will change.
