Question 1

The Golgi tendon organs (GTOs) are what kind of sensory receptors?

Accepted Answer

Mechanoreceptors

Answer

Explanation:
Sensory receptors exist throughout the body and translate stimuli into sensory information. The brain uses this information to respond with output information. These receptors are divided into mechanoreceptors, nociceptors, chemoreceptors, and photoreceptors.
Mechanoreceptors allow individuals to detect touch and similar sensations, such as pressure on their shoulders from a heavy backpack. These receptors are also responsible for monitoring limb and muscle movement through proprioception.

Question 2

Which of the following is not a characteristic of Type II (fast-twitch) muscle fibers?

Accepted Answer

Slow to fatigue

Answer

Explanation:
Type II muscle fibers (fast-twitch) are able to produce more speed and power in a contraction, but the intensity of that contraction is much shorter in duration because Type II muscle fibers fatigue more quickly than Type I muscle fibers (slow-twitch).
This is mainly because Type II muscle fibers have fewer capillaries, mitochondria, and myoglobin than Type I muscle fibers. Because Type II muscle fibers have fewer capillaries, they have less oxygen delivery. Type II muscle fibers are larger in size than Type I muscle fibers.

Question 3

In regard to working with the internal obliques, what is the main muscular role of the transverse abdominis?

Accepted Answer

To isometrically stabilize the lumbo-pelvic-hip complex

Answer

Explanation:
Along with the internal obliques, the transverse abdominis is primarily responsible for providing stability to the lumbo-pelvic-hip complex.
Additionally, when activated, this muscle can create tension in the thoracolumbar fascia, supporting a straight line and protective tension in the spine. This muscle can also compress the sacroiliac joint, which increases stability.

Question 4

All of the following are potential side effects of elevated cortisol levels except:

Accepted Answer

Decreased breathing rate

Answer

Explanation:
Cortisol is a catabolic hormone, which means it is associated with the breakdown of tissue. The adrenal glands secret cortisol in response to acute stress, both physical and emotional.
When there is chronic stress placed upon the body, whether it be from overtraining, poor sleep, or inadequate nutrition, it can lead to potentially harmful side effects such as breakdown of muscle tissue, decreased fat utilization, increased body composition (specifically abdominal fat), and decreased metabolism.

Question 5

What amount of time is recommended to hold a stretch for the Golgi tendon organs (GTOs) to signal a muscle to relax?

Accepted Answer

30 seconds

Answer

Explanation:
During static stretching, muscle spindles cause the protective muscular contraction to make sure the stretch is not taken too far. After approximately 30 seconds of applied tension, the Golgi tendon organ (GTO) will signal for the muscle to relax. After 30 seconds, the muscle becomes uninhibited, and that is when a greater stretch can be achieved.
