2. after a fierce tackle on the line of scrimmage, a football player briefly loses consciousness. when he regains it, the team doctor begins asking him questions. the player knows his name, the date, his team name, and how he got to the game. he also remembers where he lives and events that happened during his childhood. when given a list of seven digits to remember for 15 seconds, he has no trouble doing so. so far, the doctor is relieved. exerting caution, the doctor tells the player to go sit at the end of the bench. fifteen minutes later, she approaches him again and says, “let's run through that battery of memory tests again.” the player replies, “what memory tests? this is the first time i've seen you today, doc.” which parts of the memory and brain systems are working, and which are not?

The player has problems in the frontal part of the brain, in the pre-frontal lobe where short-term memories are stored. However, the player presents the maintenance of long-term memories, which means that the hippocampus (brain region) was not affected.

Explanation:

As you saw in the question above, the player has no memory loss in information that happened over a long period of time, such as childhood things, his name and what he was doing at the place where he suffered an injury and how he got there . This means that the hippocampus was not harmed by the blow the jagador received. The hippocampus is a region deep in the brain that stores long-term memories.

However, the player showed a deficiency in storing short-term memories, as he did not remember the doctor who attended him, nor the tests he performed the day before. This means that the player has damaged the frontal area of his brain, in the region of the prefrontal lobe where short-term memories are stored.

activity

the category "activity" includes exercise, rest and sleep. there is much confusion about the role that exercise and sleep play in health. like diet, activity is an area where each person can take control.    

vigorous physical activity puts demands on all body systems to work harder. the body responds to these demands by becoming stronger and more efficient. the health benefits of exercise include improved metabolism, increased muscle and bone strength, more efficient cardiovascular (heart and blood vessel) function, larger lung capacity, tension reduction, and improved sleep.

the most efficient way to obtain these benefits is through regular aerobic exercise. aerobic exercise involves the large muscles of the body, particularly the legs. examples include brisk walking, jogging, swimming and bike riding. exercise is most enjoyable when it is incorporated into recreation and becomes a regular part of your normal daily activities.

the benefits of regular aerobic activity are becoming more widely understood and accepted; however, the benefits of sleep are often ignored. sleep deprivation can suppress the body's immune system, and has been associated with depression. healing activity is accentuated during sleep. two aspects of sleep must be considered: quality and quantity.

many people just don't allow enough time for sleep. they regard it as a waste of time and use drugs such as caffeine to stimulate their exhausted bodies into action. some people allow plenty of time for sleep, but the quality of their sleep is poor. regular exercise is often effective in people improve their ability to fall asleep. physically fit people spend more of their sleeping time in deep sleep, and in rem (rapid eye movement), or dreaming sleep, the more restorative stages of sleep. people who are getting enough sleep wake spontaneously and feel refreshed.

psychology

psychological health is characterized by high self-esteem and is dependent on two primary features: productive activity and effective interpersonal skills.
