Study Notes

Skeletal Muscle Overview

Skeletal muscles are the primary component of the muscular system.
Each consists of muscle fibers, connective tissues, and nerves.
These tissues work together to create movement of bones.
The chapter explores different muscle groups, their actions, and how they move bones.
It also details muscle fiber anatomy and metabolism, explaining muscle contraction at a cellular level.
Muscle contractions provide the energy for movements.
