muscle tissue group together to form
organ systems
organs group together to form
muscle nervous and epithelial tissue
digestive system
tongue esophagus and intestines
Four basic tissue types
muscle nerve connective epithelial
contract or relax makes them shorter or thicker
stimulated by nervous tissue
600 in the body
work in pairs one contracts the other relaxes
muscle types
Involuntary Skeletal Cardiac Nerve Connective Epithelial
muscle pairs
bicep andtriceps
flexor andextensors
deltoid and pactoralis
strength and flexibilty
increased with exercise
brings more blood to the muscles
more blood= more oxygen= more respiration= more energy
muscle injuries
strain, tendon injury, cramp
overworked or stretched
may have small tear in the muscle, blood vessel or nerve fibers
caused by sudden or other quick movements and you haven't warmed up
pain even when at rest redness swelling
ice packs rest ibuprofen for a few days
Tendon injury
can be strained or torn
if strained treat like a strain
if torn get surgery

may be caused byoveruse or imbalance of electrolytes

major functions of skeletal system
provide shape and support
allows movement with help from muscles
protects your organs
produces blood cells
stores minerals until your body needs them
vertebral column
26 small bones called vertebrae
can slide about 12 degrees to the left or right
column can rotate
joints of skeleton
joint-where two bones meet
allow for different types of movement
