23
Q

A

24
Q
Explain the route blood flow beginning when it exits the heart and ending when it re-enters the heart through the inferior and superior vena cava.
A
As blood leaves the heart, it is carried by the arteries. As arteries lead away from the heart, their branches to form a “tree” of smaller, microscopic vessels called arterioles. Eventually, the arterioles develop into “beds” of much smaller structures, the capillaries. Blood passes from the capillary beds to small venous vessels called venules. As venules lead back to the heart, they increase in size and become veins (eventually leading to the inferior and superior vena cava)
25
Explain the route blood flow beginning when it leaves the right ventricle of the heart and enters left atrium.
The right ventricle pumps the blood into lungs through the pulmonary arteries. In the lungs, the blood picks up a fresh supply of oxygen and gives off carbon dioxide. The oxygenated blood returns from the lungs to the left atrium through the pulmonary veins.
26
Explain the concept of "form follows function" as they relate to the skeletal system and describe the importance of exercise and maintaining bone density throughout life.
Wolff's law indicate that changes in the bone structure coincide with the changes in bone function. That is, when a skeleton is subject to stressful forces, such as those that occur when exercise, it responds by laying down more bone tissue, thereby increasing its density. Conversely, when individuals experience prolonged period of bed rest due to illness or injury, their bone loses mineral and become less dense.
27
What axis? Imagine a pin that inserts through the joint from front to back (anteriorly and posteriorly). Because of the pin's position, the only movement allowed around this axis is lateral movement (abduction or adduction) in the frontal plane.

Define Autogenic inhibition and explain how fitness professionals can take advantage of each during a stretching routine.
Autogenic inhibition is an automatic reflex relaxation caused by stimulation of a Golgi tendon organ (GTO). This can be a advantageous during static stretching routine, in the after 7 to 10 seconds of low force stretch, a GTO response is activated, allowing further muscle stretching.
53
Define Reciprocal inhibition and explain how fitness professionals can take advantage of each during a stretching routine.
Reciprocal inhibition is a reflex in the inhibition of the motor neurons of antagonists when the agonists are contracted. This can be advantageous during a dynamic stretching routine, that low-grade muscle contractions of the antagonists muscle can reduce tonicity in the agonist muscle, allowing the muscle to be more easily be stretched.

What is the function of the Golgi tendon organ (GTO) ?
its located b/w the muscle belly and its tendon. Its function is to recognize when there is too much tension on the muscle. Either stretching too much or contracting too tightly. It causes an inhibition (ceased) of the contraction known as autogenic inhibition. This allows the muscles to relax and resulting in contraction of the opposite muscle group.
100
What is the function of muscle spindles?

This contraction causes the antagonist muscle (the opposite muscle to relax). This is known as the receptacle inhibition.
