What is Newton's Third Law
For every action there is an opposite reaction
|
Passive: when a muscle cannot lengthen anymore, occurs with antagonist of muscle
Active: when a muscle cannot shorten anymore, occurs with agonist of muscle
Explain the difference between active and passive insufficiency
|
What is Open kinetic chain
What is it called when the the proximal segment remains stationary and the distal end is free to move
|
31 pairsWhat is the total number of pairs of spinal nerves
What is the total number of pairs of spinal nerves
|
What is eccentric contractionWhat contraction produces the strongest force?
What contraction produces the strongest force?
|
What is second class lever
What lever favors effort?
|
Excitability
Contractility Extensibility Elasticity
Name one of the four properties of a muscle tissue
|
What is osteokinematics
What is the movement of the long bone around an axis
|
What is Golgi Tendon Organs
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 are the brain and spinal cord
What makes up the Central Nervous System
|
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.
Explain how the difference in the muscular moment arm can affect the outcome of an object of mass in terms of intertia
|
What is force-power relationship
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) |
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 is the convex-concave principle?
|
What is flexor withdrawal reflex
What reflex is rapidly flexing your muscles to protect your body from damaging stimuli?
|
What is the plastic region
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 transverse plane
Longitudanal axis allows movement on what plane?
