The Skeletal System Bones Section 2 Bone Structure The skeleton, shown on the next slide, is composed of many bones. If the bone tissue does not have any visible open spaces, it is called compact bone. Bone tissue that has many open spaces is called spongy bone. Bones contain a soft tissue called marrow. Bone Growth Most bones start out as a flexible tissue called cartilage. As you grew, most of the cartilage was replaced by bone.

The Muscular System Use It or Lose It Section 3 Resistance Exercise Resistance exercise is a great way to strengthen skeletal muscles. During resistance exercise, people work against the resistance, or weight, of an object. Aerobic Exercise Steady, moderately intense activity is called aerobic exercise. Jogging, cycling, skating, swimming, and walking are aerobic exercises.

The Muscular System Muscle Injury Section 3 Muscles Attach to Bones A strain is an injury in which a muscle or tendon is overstretched or torn. People who exercise too much can hurt their tendons. Inflamed tendons is called tendonitis. Some people try to make their muscles stronger by taking drugs. These drugs are called anabolic steroids. They can cause long-term health problems.
