| These organs keep the body at a constant temperature ______ | muscles |
| Compact bone tissue functions to | support the body |
| The lightweight tissue found inside bone is called | spongy bone |
| Your brain is protected by your skull. Your skull is part of the | axial skeleton |
| The appendicular skeleton includes the | shoulder |
| Functions of the skeletal system include | providing support and protection |
| The human body has | many systems that work together |
| What happens if one part of a system breaks down? | the system suffers. |
| What are two types of joints that connect bones in your skeletal system? | immoveable and movable |
| Which kind of joint allows you to bend your elbow? | hinge |
| What function do the ribs have in the skeletal system? | protect the heart and lungs |
| Muscles help maintain body temperature by | releasing heat energy when they move |
| What are the two types of bone? | compact and spongy |
| What are the main divisions of the human skeleton? | Axial skeleton and appendicular skeleton |
| What is the function of compact bone? | provide protection for spongy |
| What is the function of spongy bone? | provide a place to store bone marrow. |
| Which type of bone is hard? | compact |
| Which type of bone has holes and is lightweight? | spongy |
| What do we call the framework of the human body? | skeleton |
| The cranium, vertebra and ribs compose which part of the skeleton? | axial |
| The hips, shoulders, legs and arms compose which part of the skeleton? | appendicular |
| The framework of bones that supports the body, protects internal organs, and anchors all the body's movement | skeletal system |
| The tough, hard outer layer of a bone | compact bone |
| Strong, lightweight tissue inside a bone | spongy bone |
| The central part of the skeleton, which includes the cranium, the spinal column, and the ribs | axial skeleton |
| The bones of the skeleton that function to allow movement, such as arm and leg bones | appendicular skeleton |
| Muscles work with what type of action? | pulling action |
| In addition to providing movement, muscles also function to | maintain temperature and posture |
| What stimulates muscle growth? | increased physical activity |
| What type of muscle is voluntary? | skeletal |
| A feeling of soreness several days after exercise indicates | torn or damaged muscle fibers |
| Muscles are attached to your skeleton by | tendons |
| What are the three functions of muscles? | movement, maintaining body temperature, and maintaining posture |
| Allows movement | muscular system |
| A muscle that attaches to the skeleton | skeletal muscle |
| A muscle that can be moved at will | voluntary muscle |
| Muscle that performs involuntary movement and is found inside certain organs, such as the stomach | smooth muscle |
| A muscle that moves without conscious control | involuntary muscle |
| The muscle that makes up the heart | cardiac muscle |
| The muscles of the body that, together with the skeletal syste, function to produce movement | muscular system |
