Learning Targets (I Can’s)
Overview of Muscle Tissues



I can describe similarities and differences in the structure and function of the three
types of muscle tissue and indicate where they are found in the body.
I can define muscular system.
I can define and explain the role of the following: endomysium, perimysium,
epimysium, tendon, and aponeurosis.
Microscopic Anatomy of Skeletal Muscle

I can describe the microscopic structure of skeletal muscle and explain the role of
actin- and myosin-containing myofilaments.
Skeletal Muscle Activity






I can describe how an action potential is initiated in a muscle cell.
I can describe the events of muscle cell contraction.
I can define graded response, tetanus, isotonic and isometric contractions, and muscle
tone as these terms apply to a skeletal muscle.
I can describe three ways in which ATP is regenerated during muscle activity.
I can define oxygen debt and muscle fatigue and list possible causes of muscle fatigue.
I can describe the effects of aerobic and resistance exercise on skeletal muscles and
other body organs.
Muscle Movements, Types, and Names



I can define origin, insertion, prime mover, antagonist, synergist, and fixator as they
relate to muscles.
I can demonstrate or identify the different types of body movements.
I can list some criteria used in naming muscles.
Gross Anatomy of Skeletal Muscles

I can name and locate the major muscles of the human body (on a torso model,
muscle chart, or diagram) and state the action of each.
Developmental Aspects of the Muscular System

I can explain the importance of a nerve supply and exercise in keeping muscles
healthy.
