skeletal muscle

Type: Concept

As of November 2026, skeletal muscle has been mentioned in one podcast episode on Jamie Kern Lima (Feb 2026). Central theme of the episode, discussing the importance of skeletal muscle for metabolic health and longevity.

Skeletal muscle is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle. They are part of the voluntary muscular system and typically are attached by tendons to bones of a skeleton. The skeletal muscle cells are much longer than in the other types of muscle tissue, and are also known as muscle fibers. The tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres.
