Definition
The more moveable bone
Moves toward the more stable bone |

|
|
Term
| Reversal of muscle action |
|
Definition
| When the origin moves toward the insertion |
|
|
Term
|
Definition
| the muscle that is contracting |
|
|
Term
|
Definition
| the muscle that is relaxed and on the opposite side of the joint from the agonist |
|
|
Term
|
Definition
| force built up within a muscle |
|
|
Term
|
Definition
| Stretching a muscle involving non contractile units of a muscle |
|
|
Term
|
Definition
|
|
Term
|
Definition
| slight tension that is present in a muscle at all times, even when muscle is resting |
|
|
Term
|
Definition
| the distance from maximum elongation to maximum shortening |
|
|
Term
|
Definition
| the point at which a muscle cannot shorten any farther |
|
|
Term
|
Definition
when muscle cannot be elongated any farther without damage to its fibers
occurs to the antagonist |
|
|
Term
|
Definition
| functional use of passive insufficiency (flexor and extensor muscles) |
|
|
Term
| Tendon action of a muscle is also called |
|
Definition
|
|
Term
|
Definition
muscle contracts, producing force without changing the length of the muscle
(holding the hand rail on the bus-muscles are contracted but no joint movement occurs) |
|
|
Term
|
Definition
| muscle contracts and the muscle length and joint angle changes |
|
|
Term
|
Definition
| joint movement is produced by muscles shortening and the attachments move toward eachother (flexion at the elbow) |
|
|
Term
|
Definition
| joint motion but the muscle appears to lengthen, attachments separate (extension at the elbow) |
|
|
Term
|
Definition
muscle attachments move closer together
movement is usually occurring against gravity (a raising motion)
it is an acceleration activity |
|
|
Term
|
Definition
muscle attachments move farther apart
movement usually occurs with gravity (a lowering motion)
the contraction is used with a deceleration activity |
|
|
Term
|
Definition
for when a muscle is too weak to move against gravity
(having patient do abduction and adduction laying down) |
|
|
Term
|
Definition
| can be done with special equipment\resistance to the part varies, but the velocity, or speed, remains the same |
|
|
Term
|
Definition
also the agonist
muscle or muscle group that causes the motion |
|
|
Term
|
Definition
| a muscle that s not as effective but does assist in providing that motion |
|
|
Term
|
Definition
antagonist contracts at the same time as the agonists
|
|
|
Term
|
Definition
| a muscle or muscle group that supports, or makes firm, a part and allows the agonist to work more efficiently |
|
|
Term
|
Definition
| when a muscle can do two or more actions but only one is wanted, a neutralizer contracts to prevent the unwanted motion |
|
|
Term
|
Definition
| works with one or more other muscles to enhance a particular motion |
|
|
Term
|
Definition
| requires that the distal segment is fixed (closed) and the proximal segments move |
|
|
Term
|
Definition
| the distal segment is free to move while the proximal segments can remain stationary. |
|
|
Term
| what properties do muscles have |
|
Definition
| irritability, contractility, extensibility, and elasticity |
|
|
