Summary
Muscle structure and function are explored through multiple choice questions. Students get to test their knowledge of muscle components, actions and processes.
Muscle functions and components
Functions of muscle are listed. The smallest component of a myofibril is identified. Different parts of a muscle cell are named.
Action potentials and muscle contraction
Ions involved in action potentials are named. Stages of muscle contraction are described. Molecules needed for muscle contraction are listed.
Muscle proteins and energy production
Muscle proteins that bind to calcium are named. Energy production in muscle is described. The conversion of pyruvic acid is explained.
Specific muscles and their actions
Muscles of mastication are listed. Muscles that elevate the scapula are named. Muscles that attach to the scapula are identified. Quadriceps muscles are described.
