Definition
Discipline that uses principles of physics to quantitatively study how forces interact within a living body. |
|
|
Term
|
Definition
Branch of mechanics that describes the motion of a body without regard to forces or torques that may produce a motion. |
|
|
Term
|
Definition
describes a linaear mtion in which all parts of a rigid body move parallel to and in the same direction as every other part of the body. |
|
|
Term
T/F. Translation can occur in a straight line or a curved line? |
|
Definition
|
|
Term
|
Definition
Describes a motion in which a rigid body m oves in a circular path about some pivot point. |
|
|
Term
T/F. All synovial joints in the body possess at least some translation, driven actively by muscle or passively owing to the natural laxity wihtin th estructure of the joint |
|
Definition
|
|
Term
|
Definition
slight passive translations that occur in most joints |
|
|
Term
|
Definition
Describes the motion that occurs between the articular surfaces of joints. |
|
|
Term
What do convex/concave relationships provide for joints? |
|
Definition
Improves their congruency, increases the surface area for dissipating contact forces, and helps guide the motion between the bones. |
|
|
Term
|
Definition
Position of maximal congruency. In this position most ligaments and parts of the capsule are pulled taut, providing an element of natural stability to the joint. Accessory joints minimal. |
|
|
Term
|
Definition
all positions other than a joint's close-packed position. Ligaments and capsules are relatively slackened allowing an increase in accessory movements. Least congruent. |
|
|
Term
|
Definition
Branch of mechanics that describes the effect of forces on the body. |
|
|
Term
T/F A force is directly proportional to the acceleration of the mass. |
|
Definition
|
|
Term
|
Definition
Denotes the internal resistance generated as a tissue resists its deformation divided by its cross-sectional area. |
|
|
Term
|
Definition
Ratio of tissue's deformed length to its original length |
|
|
Term
Is plastic energy recoverable from a muscle? |
|
Definition
|
|
Term
|
Definition
Tissues when the stress-strain curve changes as a function of time. |
|
|
Term
|
Definition
Describes the progressive streain of a material when exposed to a constant load over time. |
|
|
Term
|
Definition
Muscle or muscel group that is most directly related to the initiation and execution of a particular movement. |
|
|
Term
|
Definition
Muscle or muscle group that is considered to have the opposite action of a particular agonist. |
|
|
Term
|
Definition
A pair of muscles when they cooperate during the execution of a particular movement. |
|
|
Term
|
Definition
formed when two or more muscles simultaneously produce forces in different linear directions, although the torques act in the same rotary direction. |
|
|
Term
|
Definition
Ratio of Internal moment arm to external moment arm. |
