 skeletal system | store fat and other minerals, makes new blood cells, and has connective tissue that protects the internal organs |
| muscular system | provides to force that required for body movements, controls heartbeat, controls movement of food through the digestive system |
| both the skeletal and muscular systems | contain blood vessels and nerve tissue, allows you to ride a bike or skateboard, and is made up of living cells |
| ligaments | connective tissues that connect bone to bone |
| cardiac muscle | found only in the heart and controls the heartbeat |
| tendons | connective tissues that attaches muscles to bone |
| skeletal muscle | a type of muscle that works in pairs to move the bones |
| cartilage | connective tissue found between bones to cushion bones and gives shape and flexibility to other body parts |
| smooth muscle | muscle that control involuntary movements in the internal organs of the body |
| Ball and Socket joints | are found where bones are able to move in complete rotation or circular motion such as in the hips and shoulders |
| Gliding Joints | are found where bones slide over each other like in the wrists and ankles |
| pivot joints | rotate around each other like in the neck |
| hinge joints | are found in the fingers and toes |
| muscle | makes up 85% of your body weight |
| 600 | the human body has about ___ muscles that are responsible for all the body's movements |
| Involuntary | muscles are not under your control |
| Voluntary | muscles that are under your control |
| skeletal muscle | voluntary; striated; reacts quickly and tires quickly; move bones, works in pairs, flexors contract while extensors allow a joint to straighten, attached to bone by tendons |
| smooth muscles | involuntary; smooth; reacts slowly and tires slowly;controls movements of internal organs; moves food through the digestive system, lines the blood vessels, bladder, and reproductive organs |
| cardiac muscles | involuntary; striated; tires slowly; found only in the heart and controls the contractions of the heart muscles that cause our heartbeat |
| cramps | they occur when entire muscle contacts and stays contracted |
| joint | a place in the body where 2 bones come together |
| osteoporosis | a condition in which the body's bones become weak and break easily |
| a vertebrae | one of the 26 small bones that make up your back bone |
| cartilage | a type of tissue that is made up of a connective tissue that is more flexible than bone |
| a ligament | the strong connective tissue that holds the bones together in a movable joint |
| bones | they help body maintain stable internal conditions by regulating the release of the minerals calcium and phospherous |
