Muscular Objectives
Muscular Overview

Muscular Structure
List and describe basic muscle system functions; describe the basic microanatomy of muscles, including what is meant by a “bundle within bundle” structure; and identify key muscles (or muscle groups), including muscles with opposing actions.
Tendons & Ligaments
Describe the functional difference between a tendon and a ligament and explain why both are hard to heal; and explain what is specifically injured when someone has a knee ligament injury, carpal tunnel syndrome, rotator cuff, or plantar fasciitis.
Muscles & Exercise
Describe the impact of aerobic and anaerobic strength-training exercises on skeletal muscles; provide examples of activities that demonstrate grip strength and muscle fatigue; and list and describe exercises that target specific muscles (or muscle groups) and describe what happens to organs in sports-related injuries.
