Sixth Sense: The Vomeronasal Organ Essay -- Biology Essays Research Pa

Sixth Sense: The Vomeronasal Organ "We are all more influenced by smell than we know." (Hercule Poirot) ....Murder in Retrospect, Agatha Christie Biologists have long realized that the noses of most vertebrates actually contain two sensory channels. The first is the familiar olfactory system, which humans possess. The second channel is the vomeronasal complex, a system that has its own separate organs, nerves, and connecting structures in the brain. The function of the vomeronasal system is the detection of pheromones, chemical messengers that carry information between individuals of the same species. It was widely believed (as I found in some of the older texts I examined) that humans had long ago discarded this sensory system somewhere along evolution's trail. But convincing behavioral and anatomical evidence has since brought the notion of a human vomeronasal organ (VNO) into the realm of scientific fact. Some thirty years ago, when anatomist David Berliner was studying human skin composition using scraped skin cells from the insides of discarded casts, he found that when he left vials containing skin extracts open, his lab assistants would become more friendly and warm than usual (1). When, months later, he decided to cover the vials, the warm and relaxed behavior was noticeably reduced. These findings led him to investigate the possible existence of odorless human pheromones and a "sixth sense" organ to detect their presence, a VNO. While this early evidence was not empirical, anatomists have since found that all humans display two tiny pits, with duct openings, on both sides of the septum just behind the opening of the nose (3). The duct leads into a tubular lumen lacking a thick, distinct sensory epithelium. ... ...ture textbooks will attribute to humans this mysterious, unconscious sixth sense.

Psychology and clinical psychology Essay

Abnormal psychology and clinical psychology deals with the disorders of mental health. Anxiety disorders, cognitive disorders, depressive disorders, communication disorders, disruptive behavior disorders, mood disorders and personality disorders. All these disorders are abnormal which are reflections of a very serious and concerned situation. Q. 1. What happened to one’s mind when one is woken-up by a strange or scaring noise? Ans: A normal person whose sleep is disturbed by a scary or a strange noise, wakes up with in a disordered mood. First of all a good night sleep is disturbed and mind starts thinking to find out what is wrong in the vicinity and nearly in about less than five minutes, sleepy mood disappears and instead awakens one’s mind to find out what went wrong at that moment. Men seldom feel threatened by scary noises and instead are successful in finding the realities in that situation. This is again dependent on the mental health and physical tiredness of a person as to how one’s mind reacts to these strange noises. However, a common view is that strange noises certainly wake up people from sleep and generally minds search the cause and the place where from the strange noise is heard. Q. 2. How could panic or fear interfere or disrupt with normal decision making or thinking. Ans: Panic leads to anxiety disorder which makes a particular situation to go beyond control. For instance, all of a sudden, a lion enters a home, the owner is in great panic and is out of power in decision making. It takes time to regain normal thinking in order to make a plot to cage lion in home. Some of the symptoms of anxiety are faster heart beat, heavy perspiration, stammering, hands and feet turning cold, extreme discomfort and restlessness. In both the above instances, there is a severe symptom for nervous breakdown or any abnormal disorder which may be either psychological or physical. Q. 3. Does the reaction time differ when one if fully awake and awaken by strange noise or sound? How? A fully awake person immediately researches about the issue and considers necessary steps whereas for a person who awoke from sleep, reacts slowly to the problem. For instance, a brick from a construction apartment falls on a car which is parked nearby, makes a huge sound and car owner reacts immediately and files a case against contractor. The same incident takes place in the middle of the night, car owner awakes from the middle of the sleep and finds car is broken, it takes time to react and to verify the facts of incident. Therefore the reaction time varies between a person who is fully awake and the person who is awakened by strange noise. 4. How does the environment or circumstances affect our behaviors or the way of thinking? Thinking is often lead by environment that a person resides in. Thinking at home is quite relaxed, thinking in office is quite fast, thinking in a situation is quite stressful and thinking in bed is again in a relaxed mood by reading a magazine or a newspaper. The pattern of thinking differs. For instance, behavior and thinking pattern in trains and airplanes is different such that passengers are all seat-belted, relaxed and at times doze off to sleep until destinations are reached. In panic situations, pattern of behavior changes such that yelling in anxiety, scream when in danger and calling out for help and assistance are some of the abnormal behaviors that outbreak among people. 5. Is there any sort of training that you would recommend that would prepare staff mentally who might be sleeping during high cries at the middle of the night (e. g. crisis intervention or crisis management). For instance, military personnel improve their reaction time and decision making through training allowing them to be able to get ready within 5 minutes from sleep and be able to make sound judgment or decisions. How can we compare military person vs. a regular person? Training about crisis management is quite a practical approach to staff. For instance, a burglar enters apartment and is immediately caught by the residents who acted with great courage. The essential technique that can be practiced is to predict crisis and have a pre-designed plots to attack crisis or risk situation. For instance, diffusing an explosive is a technique and requires skill, similarly, to counter-attack any situation, one has to be prepared in advance going by the environment one is placed in. A military person can never afford to be in a relaxed mood whereas an analysis has to be made each time, about the positive threats that creep in from enemy or from any unlawful forces. By and large there is a huge difference between a military person’s sleep and a regular person’s sleep basing on the activity and exercise that varies between the two. A military person is constantly on a low or high degree of stress and tension whereas a regular person carries a minimum risk depending on the regular activity that is being performed as daily chore of office-going. Conclusion Everything is a matter of acceptance as to how one reacts to a situation, whether by self-management or by seeking the guidance and help of other sources. This depends on the status of mind that one has both during the awakening time and sleeping time. The degree of panic is initially high, a person always possesses enough capacity to react to the situation in order to control and handle the issue effectively.

Human Trafficking And Sexual Exploitation - 1493 Words

Intro/where and how the problem began: We often hear the saying â€Å"Love the women in your life.† After all, they are the ones who birthed us, nurtured us, allow us to have children of our own to care for, and etc. However, they are also the main target for the human trafficking industry of sexual exploitation. Human sex trafficking can date back to thousands of years ago, but the most known period of human trafficking were portrayed during African slave trade (Oster). That being said, alongside the forced labor included among enslavement, the second most popular form of human trafficking is sexual exploitation, mainly among women and children (Deshpande and Nour). As stated above, figure 1 proves that sexual exploitation remains to be one†¦show more content†¦Therefore, assumptions that the sufferers are willingly participating in that kind of degrading work are easily made, and those assumptions cause this atrocious crime to be pushed out of the public view. Each of them has a story The misinterpretation of the fact that sex trafficking sufferers do not willingly participate in that industry, can occur from failing to acknowledge that every victim has a story. Each of them suffer in different ways and have been forced into the industry facing different circumstances. Some circumstances could include those who are captivated by invalid promises of a job, forced to sell sex by their own family members, or even a romantic relationship where one of the partners manipulates the other into prostitution (Sex Trafficking). The last example was just the beginning of the horrors that Ayesha, a sex trafficking survivor from India, had to face. Ayesha just wanted to settle down with the love of her life like any other average 13-year-old in Bangladesh, where marrying off young is extremely common. Although Ayesha did not turn out to be the average 13-year-old she hoped to be, her story is not unheard of.
