Anotomical Movements Flashcards
Decrease in the angle of a joint
Flexion
Increase in the angle of a joint
Extension
Movement of a body part away from the midline
Abduction
Movement of a body part towards the midline
Adduction
Movement of the end of a bone in a circular motion
Circumduction
Movement of a body part around a central axis
Rotation
Rotation of the hand so the thumb moves towards the body
Pronation
Rotation of the hand so the thumb moves away from body
Supination
Decrease in angle of joint between foot and lower leg
Dorsi flexion
Increase in angle of joint between foot and lower leg
Plantar flexion
Ability to react rapidly to chemical or electrical signals
Excitability
Ability to develop tension while shortening for movement to occur
Contractability
Ability of muscles to stretch beyond their normal resting length when a force is applied
Extendability
Ability to return to its original shape after being stretched
Elasticity
Muscle that causes major action
Agonist
Muscle that relaxes to allow movement to occur
Antagonist
Process of one muscle contracting while others relax to allow movement
Reciprocal inhibition
Functions of circulatory system
Circulates blood, transports water oxygen and nutrients to the body, transports waste away form cells, helps fight disease through blood cells
2 upper chambers of the heart
Atria
2 lower chambers of the heart
Ventricles
Side of heart that receive deoxygenated blood and pumps it to the lungs
Right side
Side of heart that receives oxygenated blood from lungs and pumps to tissues of the body
Left side
Large thick-walled blood vessels that carry blood away from the heart
Arteries
Tiny blood vessels between ends of arterioles and venules
Capillaries
