Brain cells and brains evolved pretty recently – about 250 million years ago, compared to the appearance of the first life-forms to arise. †¢ First evolved neurons and muscles to assist animals with movement. †¢ Nerve net – a connection of neurons that receive sensory information and send signals to other neurons that are involved in muscle movement. †¢ The first bilateral symmetry was described in flatworms, the nervous system on one side is almost identical to the other side, the human nervous system is arranged the same way. †¢ Segmentation, first observed in earthworms, whose bodies consist of several repeating segments, just like a human spinal cord. †¢ Ganglia. The first brain-like structure (a collection of neurons that function somewhat like brain) was found in clams, octopuses, snails, and insects. †¢ Spinal cord connects our brain and all the body parts senses. Was first found in highly evolved chordates. †¢ Brain. Amphibians, reptiles, birds, and mammals share this unique part of our central nervous system, but the human brain appears to be the largest relative to body size. It is believed that our ancestors’ brains evolved from changing their life-styles: having an upright posture, constructing and using tools, and developing language. 2. The human brain and a spinal cord make up the central nervous system (CNS), which is responsible for mediating our behavior; it processes the afferent sensory information carried by the peripheral nervous system (PNS) – allShow MoreRelatedA Brief Note On Stroke And Its Effects On The Brain2169 Words   |  9 Pageswhat is this horrific and sudden disease called stroke?

Why Do People Create False Identities And What Are Its...

Social media, a national phenomenon that is at the tip of everyone s fingers. Whether it’s Facebook, Instagram, or twitter people can’t go a day without it. While most individuals think social networking is a great way to meet new people, it only compels people to do unethical things. This includes creating fake profiles and posing as another person. As individuals are creating these fake profiles they aren’t realizing the effect their lies are having on others as well as their own self-esteem. So, why do people create false identities and what are its outcomes? Creating false profiles has become a common theme amongst the social networkers and has caused great issues. Both teens and adults are a part of this rising ordeal. People are creating profiles of who they wish they can be and are afraid to express themselves in fear of being rejected. Though it may seem like creating a fake profile is a petty matter, it is deeply affecting people’s conception on social media. Instead of seeing social media as a way to meet and keep in touch with people, individuals fear that social media websites are filled with con artist.

Concept of Community Free Essays

Concept of Community 1 Running head: Concept of Community Concept of Community Abstract The purpose of this paper is to discuss the concept of community. The paper will explore the differences and definition between community and aggregate. The author will further discuss specific identification and description of an aggregate. We will write a custom essay sample on Concept of Community or any similar topic only for you Order Now The paper will conclude with the writer’s personal expression regarding this topic. Community vs. Aggregate Public health nurses and other care providers face various roles and challenges when working within the community. It is significant that nurses understand the differences between aggregate care vs. ommunity based approaches to health care and service delivery. A community, in public health, is a defined population. The focus of public health is the health of a defined population of community. A community can be defined as a common interest or characteristics (age, race, gender, social class, or cultural identity), also referred to as an associate population. It can be defined by geographic boundaries, or a system (Porche, 2004). Therefore, an individual within a given population can be a member of several different communities at one time, depending on the defining characteristic of the community. And, depending on the type of community, the members may never come into contact with one another (Porche, 2004). An aggregate is a subgroup of the community population. Any community consists of multiple aggregates. Community aggregates can be grouped into simple aggregates based on demographics or geographic locations. This is the least type of aggregate in community health practices. The most common type of aggregate is high risk aggregate. A high risk aggregate or subpopulation of the community that has a high risk commonality among its members, such as Concept of Community 3 isky lifestyle behaviors (drug users, alcoholics) or high risk health conditions (teen pregnancy). The aggregate concept is used to target specific aggregates or subpopulations within the community (Porche, 2004). An aggregate approach, targets a specific subpopulation within the community, such as teenagers at risk for teen pregnancy. For example, an aggregate study (Kelly, Sheeder, 2004), was to test the h ypothesis that teenagers who have taken home pregnancy tests (aggregate), are more ambivalent about remaining non-pregnant than those who have not, and for this reason, use contraceptives less consistently. This was supported by detailed evidence. The authors concluded that home pregnancy test taking should be regarded as a red flag by those who care for adolescents; although they are as capable of using contraceptives as their peers, test takers are less apt to do so because they expect less negative consequences from childbearing, and for this reason, may benefit more from discussing childbearing expectations than contraceptive options. Therefore, aggregate health care focuses on a specific group of people and is a more in-depth and detailed type of treatment. In contrast, the community based approach focuses interventions of the entire community, using community or population based data. In the community-based approach, the interventions are designed to affect the health of the entire community at one time. In other words, the community or public health approach is focused on the entire community. To affect the health of the entire population, the public health nurse targets specific groups and designs interventions at multiple levels (individuals, aggregate or group, family and community). Concept of Community 4 Conclusion In conclusion, Public health nurses and other care providers face various roles and challenges when working within the community. It is vital that nurses understand the differences between direct and indirect services and aggregate care versus community based approached to health care and service delivery. Within a given community, multiple partners become vital to the health and well being of populations served. Aggregate care tends to focus more on individual services and individually appropriate methods of delivery. In many circumstances however, community and aggregate based approaches may be considered one in the same. Concept of Community 5 References Porche, J. (2004).

Response to Unprepared free essay sample

â€Å"Unprepared† Response Paper â€Å"Unprepared† by Jerry Groopman, tells the story of a patient whom Dr. Groopman encountered when he was still in Medical school. â€Å"Unprepared† refers to his own inexperience as a medical practitioner and the possible missteps he took in his interaction with this patient. The patient’s name was Esther Weinberg , a twenty-nine year old Orthodox Jewish woman. Upon learning of their shared faith, Ester confides in Groopman a shameful secret involving her own infidelity and her belief that her cancer is a punishment from God that has been visited on her because of her sins. The affair was an outgrowth of a loveless marriage and an unhappy life. Esther now feels bereft of all hope; she believes her cancer is deserved and because she has no hope of changing her circumstances she lacks the motivation to fight the disease. After undergoing surgery for the cancer she continues to vacillate between accepting treatment to extend her life and accepting the cancer as a death sentence the result of a â€Å"justice with stern †¦codes of conduct, that when violated†¦triggers retribution† . . (Groopman 10). In the end, she reluctantly and with some delay accepts the treatment prescribed by her doctors, but she loses the battle and dies. I used to be a very pessimistic person; no matter what the situation I would dwell on only the negative. My mother would say that my â€Å"cup was half empty† rather than half full. The spring of my Junior year in High School this all changed. It was my during my Junior year that I met Ashley. I remember the day I first saw her- a little blonde girl with a pink bow in her hair walking across the field towards my Lacrosse team clutching her mother’s hand. We had been told that her name was Ashley Jacobs, an adorable girl with brain cancer. She has been battling it her whole life and my coach thought it would be nice to â€Å"adopt† her as a member of our team. From the minute I met her, we had an instant bond and became very close. What I believe drew me to her so quickly was her positive outlook on life. Everyday she came to our Lacrosse practices, games, and dinners with a huge smile on her face. She was so happy and positive about life even though her prognosis was not good. We had all been told that the chances of her making it to high school were slim. All I could think about was how someone could be so happy and positive when her life consists of a daily struggle to stay alive. Still, she loved coming to our practices! If she felt up to it, she would be there. Every day during practice I’d look for Ashley’s little blond head with the pink bow in her hair as she ran across the field. When she wasn’t there I worried. I wondered if she was OK, if she would make it tomorrow. But then she’d come back, always the same happy, carefree little girl I had come to love. Although Ashley is a very hopeful and enthusiastic girl, she also had her low days. When she would get sick and have to go to the hospital, she was sad to miss school, a play date with friends, a lacrosse practice with us†¦Sometimes she would be weak and have to stay in bed for days. But Ashley never lacked company. Sometimes girls from the team and I would go over with cookies and crafts and spend time with her. Her family and friends would usually be there. We’d encourage her to keep fighting and remind her of all the fun things she would do when she got better. Her friends and family gave her hope; hope that if she listened to her doctors that one day she would get better and be able to live a full and happy life. Today Ashley is doing fantastic. She is happy and as healthy as can be. We still talk on the phone and although we don’t get to see each other as much, we are still very close. Reading â€Å"Unprepared† made me recognize the importance of having hope. Without hope for a better life the patient has no reason to battle the cancer. Ironically the only respite Esther found in her former life was the affair. It was the only thing that made her feel like she was not suffocating: â€Å"to be desired was enough for her to feel that she was not suffocating† (Groopman 6). She knew that without her breasts she would no longer be desired. There would be nothing left for her to go back to. Esther also had no support to encourage her to fight. Having to undergo side effects that accompany chemotherapy is awful enough but to have to battle the disease alone, without people to confide in and for support would be impossible. Esther didn’t even have the support of her children because they didn’t even know she was sick. â€Å"You see my life,’ Esther said. ‘Everything is hidden. Even what’s wrong with me can’t be spoken’† (Groopman 10). Esther had no support from her family because her family didn’t even know about the pain she was suffering. Also because Esther believed that the cancer was retribution from a righteous God, Esther â€Å"sees her cancer as some sort of divine judgment† (Groopman 11). Esther was without hope; without hope of recovery, without hope that could be given to her by a supportive family, and without hope of ever living a happy life. It’s sad that Esther didn’t have the support system Ashley did. At the end of the reading, Groopman states that â€Å"hope can flourish only when you believe that what you do can make a difference, that your actions can bring a future different from the present† (Groopman 13). Ashley and her friends and family possess a strong hope for a cure and a better day. A hope of a bright future for a remarkable little girl with a big smile and a positive attitude. I will always believe that the support Ashley receives helps her heal and to continue to be the healthy vibrant girl she is today. Ashley always reminds me to keep hope alive, and to try to remind myself to be positive, because hope for a better day is always possible.
