Muscular System

Vocabulary Quiz

• Define the following terms on a separate piece of paper

–Elastic–Contract–Voluntary–Involuntary–Axis

Muscular System

•What does it do?–Makes all movements possible•Move all body parts•Heart beat•Breathing•Digestion

Muscular System•What are the main functions?– produce heat• Shivering – muscles rubbing together

–Produce movement•Writing, breathing

–Maintain posture• Sitting up straight

Muscular System•What are the types of muscle?– Voluntary you contract when you want

to move (skeletal muscle). Movement is not automatic–Involuntary contract automatically

(stomach, intestines, heart) movement is automatic….you cannot tell your heart or stomach to stop

Muscular System•What are tendons?–Connect muscle to bone–When a muscle contracts the tendon

moves the bone–Why not just connect muscle to bone??• Tendons are stronger and take the pressure off the

muscle so you are less likely to tear a muscle

Muscular System•What are the types of muscle

tissue?– Skeletal/ Striated voluntary, provide

movement of the body–Visceral/Smooth involuntary, form the walls of

the internal organs of the body (digestive tract, respiratory passages, walls of blood vessels) –Cardiac involuntary, forms the walls of the

heart

Muscular System• What are the basic movements of skeletal

muscle?– Adduct: moving a body part toward the midline of the

body– Abduct: moving a body part away from the midline of

the body– Extend: straightening a body part or moving it away

from the body– Flex: bending a body part toward the body– Rotate: turning a body part on its axis– Open and close openings: sphincters, like the urethra

or esophagus

Muscular System• What are the basic movements of skeletal

muscle?– Supinate: turn palm of the hand upward

medially , sole of the foot upward medially, or lie facing upward (supine)–Pronate: turn palm of the hand downward

medially, sole of the foot downward medially, lie facing downward (prone)

Muscular System• What are the basic movements of skeletal

muscle?– Inversion: turn the sole of the foot inward so

that the medial border of the foot is elevated– Eversion: turn the sole of the foot outward so

that the lateral border of the foot is elevated
