Anatomy, Physiology, and Disease Anatomy, physiology, and disease One of the es of disease that causes the largest threat to public health today is communicable disease. According to Hall, Hall and Cockerell (2011), the spread of communicable diseases is today expedited by urbanization, poverty, as well as issues of climate change that change peoples behavior hence the spread. Communicable diseases also poses the largest health threat due to the fact that they can easily be spread from one person to another. There has been improvement in terms of the impacts of communicable disease as a result of advancements in technology and continuing studies aimed at mitigating their effects, and as well reducing their incidences (Hall, Hall and Cockerell, 2011).
A good example of communicable disease that poses a huge threat to public health include HIV/AIDS. This disease is easy to diagnose; the most common diagnosis is through blood tests. In essence, testing is done in order to identify the presence of antibodies created in the body in an effort to fight the HIV (Holland, Olsen and Florey, 2007). It is worth noting that the disease is caused by a virus known as Human immunodeficiency virus (HIV). Some of the signs and symptoms of HIV/AIDS according to Hall, Hall and Cockerell (2011) include weight loss, diarrhea, coughing, dermatitis, herpes, TB, unrelenting wounds, and abscesses.
Prevention of HIV/AIDS depends on the mode of transmission. It can be transmitted through sexual intercourse, blood transfusion, and transmission from a pregnant mother to the unborn child. Prevention of the disease in relation to sexual transmission is achieved through the use of condoms and sex education. Blood ought to be screened thoroughly before transfusion to detect the presence of the disease. Pregnant mothers also ought to be tested and subsequent treatment given in case of presence of the disease (Ramaiah, 2008).
Antiretroviral drugs are used to treat the disease. These drugs are taken on a daily basis in a bid to minimize the amount of the HIV virus in the body (Ramaiah, 2008). There are also post-exposure prophylaxis medications that are used for emergency treatments when an individual has been exposed to the virus (Hall, Hall and Cockerell, 2011). There is however no known cure for the disease. These medication are only used to reduce the amount of HIV in the body in order to allow the body fight infections. Epidemiological studies have proved that HIV is transmitted through three routes namely sexual transmission, exposure to contaminated blood, and mother to child transmission. The ability of the body to maintain homeostasis is affected by HIV/AIDS by interrupting the bodys capacity to fight infections. The virus kills body cells hence making the body completely powerless when it comes to fighting pathogens and other disease causing organisms (Ramaiah, 2008).

An ovarian cycle refers to the process in which a mature oocyte erupts from the ovary and moves down to the uterus. When fertilization occurs, the egg comes to the uterus where the development of embryo begins. The response of the ovarian cycle in case of fertilization is that the uterine lining becomes thick in anticipation of implantation of a fertilized egg. The uterine lining becomes thick because of progesterone secreted by corpus luteum that forms in the ovary. In case of fertilization, the egg is implanted in the...

...Child's organism is not just a small copy of adult body (Rowland T., 2005). It has some distinctive peculiarities - morphological, functional and psychological. The different anatomical and histological structure and biochemical composition determine age-specific functional capabilities presented by immaturity of adopting mechanism, by greater sensitivity to environmental impacts (e.g. stress factors). Exercises and sport could be considered as powerful tools of optimising adaptive capabilities of child organism. Thus, which characteristics of child's' anatomy and physiology can be related to this phenomenon. Let's discuss these problems. The locomotoric system of children is developing intensively during all periods of childhood... of...

Human Anatomy and Physiology

...Human Anatomy and Physiology Human Anatomy and Physiology By studying the movements required for the execution of a kick in a football game, one can trace the various activities required to move three of the more common types of joints in the human body, the ball and socket joint, the hinge joint and the pivot joint. These motions can be seen in the hip, the knee and the neck respectively as the player swings his foot, straightens his leg and turns his head to follow the trajectory of the ball. How these joints work, including the muscles involved and the exact movements produced, will be discussed throughout this paper. Ball and Socket Joint The hip joint is a good...

...how the human muscles work in unison with each other. Some of the human specimens were arranged as if they were performing activities such as playing basketball, kicking a football and conducting an orchestra. The real shocker was a skeleton dancing with it’s own skin! Two bodies were displayed holding hands with extended arms to balance each other. I was in sheer disbelief when I realized that it is really one body – one side depicting the muscles and the other depicting the skeleton. These displays helped me understand how our bones and muscles work together as we stretch, hold hands or do any other chores. Although my textbook ‘Essentials of Human Anatomy and Physiology’ explains the mechanism of...

...HUMAN ANATOMY AND PHYSIOLOGY   Contents Synthetic Blood Synthetic blood has had a checkered history in the past few decades. Although some efforts have focused on fluorocarbons as substitutes for blood, the oxygen-carrying capacity and oxygen-releasing capacity, coupled with the ability to absorb and release carbon dioxide, has not lived up to the promise hoped for several decades ago (Moore). Part of the problem with synthetic blood is that the alternative, donor blood, has improved over the years. In 1978, when the first US patent was issued, the primary mode of transfusion was for “whole units” of blood, including platelets, plasma, red cells, white cells and other factors. Since then, blood...

...and drainage during a cold or “the flu”. The body has two types of glands known as endocrine glands and exocrine glands. The difference in these two glands is that endocrine glands are ductless while exocrine glands are essentially ducts that connect to anatomical surfaces. Most of the ducts in the body are in fact exocrine. Both of these glands act to secrete all different types of molecules (also enzymes and hormones). Once again the skin is so essential to human anatomy and physiology. It is composed of two specific layers known as the epidermis and the dermis, and a final layer called the subcutaneous layer. We will find the familiar glands of the exocrine system within the dermal layer as...

This is despite the state of the current advanced medical field’s expertise whereby it continues to affect numerous people’s lives detrimentally. However, numerous practitioners and researchers have come up with extremely conflicting, varying and confusing multifactorial theories, which they have postulated regarding what could be the aetiology of this condition (Grosset, Fernandez, Katherine & Okun, 2009).

...Reflex Action On the Basis of Auditory and Visual Stimuli: Explanation of the Case Study The system worked on the principle that both the stimuli combined (summation of stimuli) produced the response. The auditory stimuli were transmitted by stimulating the basilar membrane of the internal ear which provoked response in the inner hair cells which produced glutamate as the neurotransmitter which acted on the dendrites of the bipolar auditory nerve (1st order neurons). There are glutamate receptors which causes opening of sodium channels causing depolarization and setting of action potential in the auditory nerve .The action potential was carried from the auditory nerve to the vestibular nerve and vestibulocochlear nerves (2nd order...
