Place where two or more bones meet.
Joint
Involuntary muscle that causes movement.
Smooth Muscle
Basic unit of the nervous system.
Neuron
This system includes your heart and blood vessels that receives the most benefits from regular physical activity.
Cardiovascular System
Ongoing physical activity that raises your breathing rate and heart rate.
Aerobic Exercise
Fills the spaces between bones.
Marrow
Involuntary muscle found only in the heart.
Cardiac Muscle
Makes up 85% of the brains weight.
Cerebrum
Regular physical activity increases your basal metabolic rate-the amount of energy your body uses when you are at rest.
Weight Maintenance
Intense physical activity that lasts for a few seconds to a few minutes.
Anaerobic Exercise
By young adulthood most of this cartilage is replaced by bone.
Ossification
Muscles that you control to do activities.
Skeletal Muscles
Coordinates your bodies movements and helps with your balance.
Cerebellum
Your physical activities should include some weight-bearing exercises such as jumping rope or walking. These activities make your bones stronger and denser.
Bone Strength
An exercise in which muscles contract but very little body movement takes place.
Isometric Exercise
An overstretched or torn ligament.
Sprain
A thick strand of tissue that attaches to the bone.
Tendon
Consist of three structures: the midbrain, pons, and medulla.
Brain Stem
Good balance and coordination can also reduce your risk of injury while performing chores such as climbing ladders or carrying packages down stairs.
Balance and Coordination
Involves contracting and relaxing your muscles through the full range of a joint's motion.
Isotonic Exercise
A condition in which the bones become weak and break easily.
Osteoporosis
An overworked or overused muscle that is very painful.
Strain
These actions include such things as your breathing rate and digestion.
Autonomic Nervous System
Continuous exercise releases endorphins. Chemicals that block pain messages from reaching your brain cells. Responsible for the feelings of satisfaction and pleasure.
Psychological
Muscles contract at a constant rate. Typically involves a machine providing resistance like in a physical therapist office.
Isokinetic Exercise
