## Additional Anatomy Flashcards

Term
 Vector
Definition
 quantity describes both magnitude and direction.
Term
 Linear force
Definition
 Results when two or more forces are acting along the same line
Term
 Parallel forces
Definition
 occur in the same plane and in the same or opposite direction
Term
 Concurrent forces
Definition
 two or more forces must act from a common point but pull in different directions
Term
 Force Couple
Definition
 occurs when two forces act in an equal but opposite direction resulting in a turning effect
Term
 Torque
Definition
 also known as moment of force, the ability of force to produce rotation about an axis.
Term
 Stabilizing force
Definition
 nearly all of the force generated by the muscle is directed back into the joint, pulling the two bones together
Term
 Angular Force
Definition
 most of the force generated by the muscle is directed at rotating the joint and not stabilizing the joint
Term
 Dislocating force
Definition
 Force is directed away from the joint
Term
 state of equilibrium
Definition
 When an object is balanced, all torques acting on it are even
Term
 Gravity
Definition
 mutual attraction between the earth and an object
Term
 Gravitational Force
Definition
 always directed vertically downward toward the center of the earth.
Term
 Center of Gravity
Definition
 is the balance point of an object at which torque on all sides is equal.
Term
 Line of Gravity
Definition
 imaginary vertical line passing through the COG toward the earth.
Term
 Base of Support
Definition
 the part of the body that is in contact with the supporting surface.
Term
 Stable equilibrium
Definition
 occurs when an object is in a position that to disturb it would require the COG to be raised.
Term
 Lever
Definition
 is a rigid bar that can rotate about a fixed point when a force is applied to overcome resistance
Term
 Axis
Definition
 fixed point about which the lever rotates
Term
 Force
Definition
 causes the lever to move, usually, but not always muscular
Term
 Resistance
Definition
 must be overcome for motion to occur, can include the weight of the part being moved, gravity or external weight
Term
 Force arm
Definition
 is the perpendicular distance, or length between the line of force and the axis.
Term
 Resistance arm
Definition
 the perpendicular distance or length between the line of resistance and the axis.
