SKELETAL MUSCLE Meaning and
Definition
-
Skeletal muscle refers to a specific type of muscle tissue that is attached to the skeleton and plays a key role in voluntary movements of the body. It is one of three types of muscle in the human body, along with smooth muscle and cardiac muscle. Skeletal muscle is primarily responsible for enabling movements such as walking, running, and lifting objects.
This type of muscle tissue is characterized by its multinucleated structure, with each muscle fiber containing multiple nuclei. These muscle fibers are long, cylindrical cells that are bundled together to form muscle tissue. Skeletal muscles are attached to the skeleton through tendons, and they work in pairs or groups to perform a wide variety of movements and actions.
Skeletal muscle is striated in appearance due to the organization of contractile proteins called myofibrils within its fibers. These myofibrils contain repeating units called sarcomeres, which are responsible for the contractile properties of skeletal muscle. When the muscle is stimulated by nerve signals, the sarcomeres shorten, causing the muscle fibers to contract and generate force.
In addition to enabling voluntary movements, skeletal muscles also have other important functions. They help to maintain posture and stability, support and protect internal organs, and generate heat to regulate body temperature. Overall, skeletal muscle is an essential component of the musculoskeletal system, allowing humans to perform a wide range of physical activities.

Etymology of SKELETAL MUSCLE
The word "skeletal muscle" is derived from the combination of two terms: "skeletal" and "muscle".
1. Skeletal: The term "skeletal" is derived from the Old Norse word "skel", meaning "stick". It is related to the Old English word "sciel", which also means "stick". In the context of anatomy, "skeletal" refers to the framework of bones that provide support to the body.
2. Muscle: The word "muscle" comes from the Latin term "musculus", which means "little mouse". This name was given because the Romans thought certain muscles resembled mice. The Latin term "musculus" is derived from the Latin word "mūs", meaning "mouse".
Combining these terms, "skeletal muscle" essentially refers to the muscles that are associated with and attached to the skeleton.
