Skeletal Muscles | VOLUNTARY MUSCLE helps move the skeleton and help with body heat and posture |
Tendons | strong cords of connective tissuetha attaches muscle to bone |
Ligaments | groups of connective tissue that attach bones to bones and bones to cartiladge also provide support and strength to joints |
Muscle Tone | state of partial contraction |
Smooth Muscle | INVOLUNTARY MUSCLE found within tubular structures of gastrointestinal tract, urinary system, blood vessels, the eyes, and bronchi of resp system |
