The difference between skeletal muscle and muscle

Skeletal muscle is a type of muscle in our human body. There are many types of muscles, and there are also some other types. Different muscles have certain differences in their distribution areas and internal structures. Some people may think that skeletal muscle and muscle are the same tissue. In fact, this statement is wrong. There are certain differences between skeletal muscle and muscle. So what is the difference between skeletal muscle and muscle?

The muscles you are talking about are medically called "muscles". Muscle is divided into: smooth muscle, cardiac muscle and skeletal muscle. Smooth muscle: such as the muscles of the internal organs. Myocardium: The muscle of the heart wall. Skeletal muscle: muscles of the trunk and limbs

Skeletal muscle: a type of animal muscle. L

Smooth muscle is not under human conscious control (involuntary), while skeletal muscle is controllable by human conscious control (voluntary muscle);

Under a light microscope, the difference between the two lies in their cell shape: smooth muscle is spindle-shaped, with the nucleus located in the center, while skeletal muscle is vermicelli-shaped, that is, it is an elongated barrel shape;

Skeletal muscle cells have striations (composed of thick and thin myofilaments into sarcomeres), also known as striated muscle, but smooth muscle does not;

From the perspective of distribution, smooth muscle is distributed in the respiratory tract/digestive tract and other internal organs, and its function is to drive the peristalsis of the digestive tract; skeletal muscle is attached to the bones and is the power organ that makes the body move.

Skeletal muscles are voluntary muscles distributed in the trunk and limbs. Muscle fibers are slender and cylindrical, with multiple to hundreds of nuclei located at the periphery of the fibers. The outside of the muscle is the epimysium, which is made of connective tissue. The epimysium contains blood vessels and nerves, which extend into the muscle to separate the muscle into several muscle bundles. It itself forms the perimysium that wraps the muscle bundles, and then extends into the surrounding area of ​​each muscle fiber to form the endomysium rich in capillaries and nerve fibers.

Muscle (muscle) is mainly composed of muscle tissue. Muscle cells are slender and fibrous in shape, so they are usually called muscle fibers. In traditional Chinese medicine theory, muscle refers to the general term for the body's muscle tissue and subcutaneous fat tissue. The spleen controls the muscles, and the muscles obtain nutrition from the spleen's ability to transport and transform the essence of water and grain. Muscle: Name of anatomical structure. Therefore, whether the muscles are plump or not is closely related to the strength of the spleen. "Suwen·Ping Ren Qi Xiang Lun" says: "The spleen moistens the internal organs, and the spleen stores the qi of the muscles." "Suwen·Wei Lun" says: "The spleen governs the muscles of the body."
