Answer to Question 1

Ans:
D

Feedback:

The inverse myotatic reflex is demonstrated in this example; when too much pressure is applied to the arm and tension reaches a certain level, the Golgi tendon relaxes. Since the arm bar is being held, the only way the body can reflex is by going down toward the ground, making the attacker fall downward. In persons with spastic paralysis, the inverse myotatic reflex becomes hyperactive and produces what is called the clasp-knife reaction. The withdrawal reflex is stimulated by a damaging (nociceptive) stimulus and quickly moves the body part away from the offending stimulus, usually by flexing a limb part. The myotatic or stretch reflex controls muscle tone and helps maintain posture.

Answer to Question 2

Ans:
D

Feedback:

Cerebellar damage can resemble the effects of alcohol, because alcohol affects the cerebellum. This woman has not been drinking, but her high blood pressure puts her at risk for cerebrovascular accident.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
