For every action there is an opposite reaction
What is Newton's Third Law
|
Explain the difference between active and passive insufficiency
Passive: when a muscle cannot lengthen anymore, occurs with antagonist of muscle
Active: when a muscle cannot shorten anymore, occurs with agonist |
What is it called when the the proximal segment remains stationary and the distal end is free to move
What is Open kinetic chain
|
What is the total number of pairs of spinal nerves
31 pairs
|
What contraction produces the strongest force?
What is eccentric contraction
|
What lever favors effort?
What is second class lever
|
Name one of the four properties of a muscle tissue
Excitability
Contractility Extensibility Elasticity |
What is the movement of the long bone around an axis
What is osteokinematics
|
These detect active tension in a muscle, which not only helps them determine the appropriate force needed for a task, but also sends an inhibitory message to relax
What is Golgi Tendon Organs
|
What makes up the Central Nervous System
What are the brain and spinal cord
|
Explain how the difference in the muscular moment arm can affect the outcome of an object of mass in terms of intertia
The shorter the muscular moment arm, more effort needed. The longer the muscular moment arm, less effort needs, but also increased angular velocity so it is harder o stop the due to the mass distribution moving as a high rate.
|
What is the name of the relationship that demonstrates power produced is controlled by how quickly and powerfully the muscle contracts
(Hint: optimum power is when muscle is slightly stretched)
what is force-power relationship
|
What is the convex-concave principle?
The convex surface of the joint moves on the concave surface in the opposing motion compared to where the segment is moving
(i.e. shoulder joint) |
What reflex is rapidly flexing your muscles to protect your body from damaging stimuli?
What is flexor withdrawal reflex
|
DAILY DOUBLEEEEEEE
What region of a stress-strain curve do you reach when you no longer can return to the original shape
What is the plastic region
|
Longitudanal axis allows movement on what plane?
What is the transverse plane
