Muscles

Mr. G’s Muscles

QuestionAnswer
What are muscles? Bundles of muscle fibers held together by connective tissue
Excitability Respond to a stimulus
Extensibility The ability to be stretched
Contractibility Muscle fibers when stimulated will contract or become short and thick, this results in movement
Elasticity After contracting this trait allows the muscle to return to its original shape
The three types of muscle tissue are cardiac, visceral or smooth and skeletal or voluntary
Cardiac muscle Forms the walls of the heart and contracts to circulate blood
Visceral or smooth muscle Found in internal organs of the body i.e. digestive, respiratory, blood vessels, eye and urinary system organs. These muscles contract without conscious thought and are called involuntary muscles.
Skeletal muscle Attached to bones and causes body movement. Can be controlled and are called voluntary muscle.
Functions of muscles Attach to bones to provide voluntary movement, Produce heat and energy, Help maintain posture and Protect internal organs
Tendons Strong,tough, connective-tissue cords that attach to bones.
Fascia a tough, sheet like membrane that covers tissue
Origin The attached point of a muscle to a bone that does not move.
Insertion The attached point of the muscle that moves.
Adduction Moving a body part toward midline
Abduction Moving a body part away from midline
Flexion Decreasing the angle between two bones, or bending a body part.
Extension Increasing the angle between two bones, or straightening of a body part.
Rotation Turning a body part around its own axis
Circumduction Moving in a circle at a joint or moving one end of a body part in a circle while the other end remains stationary
Muscle tone The state of partial contracture.State of readiness to act, partially contracted at all times
Contracture A result of not using a muscle.
Atrophy Shrinking in size because muscles weren't used for a long time
Myasthenia gravis Chronic condition, nerve impulses not properly transmitted
Muscular dystrophy Inherited disease leading to muscle atrophy
Muscle strain Sudden, painful,involuntary muscle contraction
Muscle spasm Outstretching or injury to a muscle or tendon
