What is skeletal muscle innervation?

Each skeletal muscle fiber is innervated by a single motor axon. The same axon may also innervate other muscle fibers. All the fibers innervated by the same axon are called a motor unit. Skeletal muscles contain specialized proprioceptive sense organs, called muscle spindles, which function to detect muscle stretch.

How do muscle fibers produce tension?

A muscle fiber generates tension through actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same. Although the term contraction implies shortening, when referring to the muscular system, it means the generation of tension within a muscle fiber.
