| Question | Answer |
|---|---|
| what is skeletal system? | organ system that supports and protects the body |
| human skeleton inside the body | endoskeleton |
| protect the heart and lungs | ribs |
| protect the spinal cord | vertebrae |
| protect brain | skull |
| skeletal system is made of ..... and ..... and ........ | bones, ligaments, and cartilage |
| skull , vertebrae ,ribs make up the .......... skeleton | axial skeleton |
| legs ,shoulders, pelvis, and arms make up the .............. skeleton | appendicular skeleton |
| hard organs made up of minerals and tissues | bones |
| ligaments | hard, flexible strand of connective tissue that holds bones together |
| function of ligaments | connect bone to bone and movement |
| some bones fuse together when..... | human grows |
| where is the ligaments | end of bones |
| strong, flexible and smooth connective tissue | cartilage |
| dense and does not have visible spaces | compact bone |
| many open spaces bone | spongy bone |
| cushion area in a joint where bones meet | cartilage |
| protien that body produces | collagen |
| marrow | soft tissue |
| bone cells | osteocytes |
| types of marrow | red marrow and yellow marrow |
| growth plates are areas of ......... that continue | cartilage |
| what does red marrow produce | site of platet and white and red blood cells |
| what does yellow marrow produce | store fats |
| where does yellow marrow found | center of long bones |
| where does red marrow found | ribs, pelvis, skull |
| where 2 or more bones connect | joint |
| 2 kinds of joints | fixed, and movable joint |
| 3 examples of movable joints | ball and socket joint, gliding joint, hinge joint |
| what ball and socket joint do? | allow one of the bones of joint to rotate in a large circle |
| where does ball and socket joint is found? | shoulders and hips |
| what hinge joint do? | move back and forth |
| what gliding joint do? | flexibility in many directions |
| where is hinge joint? | knees and elbows |
| where is gliding joint | wrists and ankles |
| fracture | skeletal injury bones may be broken |
| broken bone can repair itself in ................weeks | 6 - 8 weeks |
| sprain | skeletal injury injury to a ligament |
| how sprain is caused? | stretching a joints too far |
| symptoms of sprain | bigger and painful |
| osteoporosis | skeletal disease disease that cause bone tissue to become thin |
| causes of osteoporosis | not getting enough calcium |
| symptoms of osteoporosis | weak bones and they break more easily |
| arthritis | skeletal disease cause a joint to swell, stiffen, painful |
| symptoms of arthritis | misshapen and difficulty to move |
| how to reduce arthritis | drugs that reduce swelling |
| muscular system | made of muscles that allow movement and flexible |
| muscle | tissue that contracts and relaxes, making movement possible |
| 3 types of muscles | smooth muscle, cardiac muscle, skeletal muscle |
| voluntary | controllable |
| involuntary | incontrollable |
| where is the smooth muscles | in internal organs and blood vessels |
| function of smooth muscles | move material |
| smooth muscle is voluntary or involuntary | involuntary |
| cardiac muscle | makes up the heart |
| cardiac muscle is voluntary or involuntary | involuntary |
| power house of cell | mitochondria |
| function of cardiac muscles | push blood and pump it |
| where is the skeletal muscles | 1. attached to bones 2. around a joint |
| function of skeletal muscles | make movement possible |
| skeletal muscles are voluntary or involuntary | voluntary |
| tendon | connects muscle to bone |
| how to bend a joint | flexor contracts and extensor relaxes to bend a joint |
| how to straighten a joint | flexor relaxes and extensor contract to straighten a joint |
| strain | muscular injury muscle injury in which a muscle is overstretched or torn |
| how do strains happen | muscle not been stretched properly or overworked |
| symptoms of strain | painful and swell |
| muscular dystrophy | muscular disease heredity disease causes muscles to become weaker over time |
| tendinitis | muscular injury tendon become inflamed or torn |
| what causes tendinitis | muscles are overused |
| how to heal tendinitis | rest to heal |
| types of exercises | muscle strength, muscle endurance, flexibility |
| increase muscle strength | resistance exercise or anaerobic exercise |
| anaerobic exercise | muscle cells contract without using O2 |
| aerobic exercise | muscle cells use O2 to contract |
| flexibility | full range of motion |
| increasing flexibility | stretching exercises |
| shoulder is an example of........................ joint | ball and socket |
| muscle work in .................. to move the body | pairs |
