Physical, Occupational, and Speech Therapies
When many people hear the word "therapy," they think of something that has caused a problem and has to be fixed. In most cases, that is true. Most people think the problem may be an injury that has to be rehabilitated or an extreme mental problem where the person needs serious help. However, therapy does not always deal with injured or mentally troubled people. Three types of therapy that help a wide range of people with their problems are physical, occupational, and speech therapies.
Physical therapy is the one that deals mostly with injuries and their rehabilitation. According to the Occupational Outlook Handbook, "Physical therapists provide services that help restore function, improve mobility, relieve pain, and prevent or limit permanent physical disabilities of patients suffering from injuries or disease" (205). Disabling conditions such as lower-back pain, cerebral palsy, arthritis, heart disease, and fractures, as well as physical injuries, are among the cases physical therapists often evaluate and treat. This therapy often includes strength-building exercises. Therapists in this field work on the person's flexibility, endurance, strength, balance, and coordination. Most therapy is done in specializing clinics or hospitals by a licensed physical therapist who has a bachelor's degree ("Physical").
Physical therapy is a fairly new practice of rehabilitation. The treatments were not widely practiced until after World War I when soldiers returned home with injuries that were able to be rehabilitated by this therapy. The profession immediately began to grow and has been popular in the U. S. since that time. The vocation is also expected to c...

A psychological mechanism is defined as an adaptation of human behavior that evolved due to evolutionary pressures. This paper focuses on the psychological mechanism of human mating strategies and the evolution of mate preferences. There are several theories to explain how differences in male and female mating strategies developed. This paper explores the parental investment theory, male mating effort as well as the role of different adaptive problems faced by males and females. The traits that humans find attractive in a partner are the ones that confer a reproductive advantage to the individual (Buss, 1994). Early in the literature there is evidence to support the theory that males and females differ in their mate preferences in such a way that males are unselective while females are choosy (Darwin 1871). However, there are also similarities in what each sex finds attractive. It is important to look at how these mating strategies evolved and why adaptive mate preferences continue to exist.
In order to understand the present lifestyles relating to different approaches and tactics applied by humans in mate choice preferences, there is the need to refer to Darwin (1859, 1871) evolutionary perspectives. Darwin (1871) sexual selection is the driving force for males and females reproductive quest for their genes survival. These driving forces have been classified into two categories as intra-sexual and intersexual mate selection.Intersexual selection is male sexual selection process whereby males compete with other males and the females choose the strongest as their ideal partner. Intra-sexual selection occurs when the male species fight among themselves and the strongest gain access to females for
Sexual selection comes in two forms. One, is direct competition between males for access to females. The other is through the females’ choice among possible mates. (pg. 148) In both types of sexual selection, the males compete for the females. The classic sexual selection arguments that Darwin first presented, were improved when genetics discovered how significant sexual recombination was to genetic variability and speciation. In our class discussion we were asked if animals and humans selected their partners in different ways. I agreed as well as disagreed that we are different in our selection. Humans and animals essentially need the same things, and when looking for a partner there isn’t much of a difference. We all look for the partner with the physical aspects that appeal to another, and for protection, the strongest is typically the best mate in both animal and human worlds. But for humans, emotions come into play, and we also chose on personality. One can have all of the qualifications that are “necessary” in the choosing of a mate, but if their personality does not cohabitate with the other party member, they will not be chosen for a lifelong relationship. Nonetheless, emotional choses may be the only true difference we have to that of
In both of these forms of selection, traits or characters are favoured that improve an individuals fitness, or in other words, the ability to pass on the most amount of genes to the next generation relative to other individuals in its population. The two major components that are necessary for an individual to carry on its genes to the next generation are survival and reproduction. As previously mentioned, males and to a lesser extent females, use traits in courtship that interfere with their survivorship. This means that a concession can be made between survivorship and mating success and that natural selection and sexual selection can apply conflicting selection tension on a
The circadian rhythm is the internal biological clock, consisting of genes and their protein product that are responsible for the “rhythmical” pattern of physiological and behavioral changes within an organism. This process has the ability to “synchronize” its cycles to external environmental stimuli and is regulated by the superchiasmatic nuclei (SCN) of the mammalian brain [1]. Melatonin, the primary hormone released from the pineal gland of the brain, along with its two G protein-coupled receptors- Mel1a and Mel1b- play a key role in the sleep cycle controlled by the circadian rhythm. When Mel1a is stimulated by melatonin, the receptor inhibits the neurons of the SCN from firing to all stimuli except for those that induce a deviation from
West Nile Virus (WNV) is an enveloped RNA virus that is transmitted from mosquitoes. The first case in North America was discovered in 1999 and it has been discovered that both birds and mosquitoes are carriers of this neuropathogen. Upon biting an infected bird, the mosquito is then infected. When the infected mosquito bites the human, the virus is transferred. Since West Nile Virus’ method of pathogenicity is zoonotic, it is not known to be transferrable from person to person.2 This flavivirus has been known to differentiate into the less serious West Nile Fever and the more severe West Nile Meningitis and West Nile Encephalitis.1
The West Nile Virus is a flavivirus that is maintained in nature by way of an enzootic cycle involving birds and mosquitos. The birds act as amplifying hosts while the mosquitos serve as vectors for the virus. Birds that become infected and develop high levels of the virus in their blood pass the infection onto mosquitoes when bit. The infected mosquito will then infect more birds when they bite. When looking at this study, it is important to note that while the West Nile Virus has been detected in at least 326 bird species, this study will only examine 6. The same goes for mosquitoes, as researchers are only interested in examining the competent species in the urban wetlands and adjacent urban residential areas in Central New Jersey. Competency
It may seem obvious to some why people mate, however there are many facets to human mating. Psychology has shown that reasons for mating have gone beyond the scope of love and physical attractiveness. People may search for mates who resemble archetypical images of the opposite-sex parent, mates with characteristics that are either complementary or similar to one's own qualities, or mates with whom to make an exchange of valuable resources (Buss 238). Although these theories play a key role in understanding patterns in human mating preferences, evolutionary psychology and sexual selection theory provide more concrete frameworks for explaining human mating.
One of the largest issues in animal sexual reproduction is the conflict of interests between the female and the male of the species. For example, multiple mating has been shown to greatly increase the fertilization rate for the male, but recent studies have shown that multiple mating also benefits the female.
Sexual selection is how a creature will appear either suitable or unsuitable for mating purposes based on traits and qualities. Most sexually selective factors can be seen as harmful or considered as disadvantageous- such as plumage in birds, or antlers on deer, or even mating calls and rituals (Miller, n.d; Puts, 2010). These traits, for instance, abundant plumage and large antlers, are thought to be disadvantageous because they can potentially lead to slower responses of the animal due to a larger mass - “the bigger they are, the harder they fall”. However, sexually selective factors can also be seen as advantageous and quite significant. Where we see these beautiful colours and patterns in fur and plumage, and large antlers on stags, we see that the organisms have an abundance of energy and nutrients so that they can create these attractive features (Miller, n.d.). The abundance of energy, strength and agility means that the organism is well fit for survival and thus attracts mates more often (Miller, n.d.). These advantageous traits of strength, energy and even intelligence, can be highly influential when creatures are searching for
Physical therapy is a fun and exciting healthcare profession that helps people. It is all about helping other people who have problems with their body, muscles, joints and other parts of their body. Patients includes accident victims and individuals with disabling conditions such as low back pain, arthritis, heart disease, fractures, head injuries, and cerebral palsy. Physical therapy will perform an evaluation of your problem or difficulty. They evaluate your problem by performing tests and measures to assess the problem. These tests includes muscle strength, joint motion, sensory and neurological, coordination, balance, observation, palpation, flexibility, postural screening, movement analysis, and special tests are designed for a particular problem. Next, they develop a treatment plan and goals and then manage the appropriate treatment to aid in recovery of a problem or dysfunction. Physical therapists are able to treat their patients by using many different treatments depending on the type of injury. Some of the treatments are electrical stimulation, hot and cold packs, infrared and ultrasound to reduce swelling or relieve pain. These treatments are used to help decrease pain and increase movement and function. Therapeutic exercises instructions will help restore strength, movement, balance, or skill as a guide towards full functional recovery. Physical therapy provides "hands on techniques" like massage or joint mobilizations skills to restore joint motion or increase soft tissue flexibility. They will focus on basic skills such as getting out of bed, walking safely with crutches or a walker, moving specific joints and muscles of the body. Physical therapists treatment includes patient education to teach them how to deal with a current problem and how to prevent the problem in the future. Such documentation is used to track the patient's progress, and identify areas requiring more or less attention. They encourage patients to use their own muscles. Their main goal is to improve how an individual functions at work and home.
Sexual selection is choosing a mate based on a preference for certain characteristics. These preferences evolved to increase the probability of survival. Females are almost always the ones to make this choice while males compete for the opportunity to mate with females and pass on their genes. Over time, genes that indicate health have often become extravagant or excessive. The advantages of sexual reproduction rather than asexual reproduction are genetic diversity and the selection of the healthiest genes to pass on.
As we all know different people experience different level of sleepiness and alertness throughout the day .The brain plays a vital role in controlling the Circadian rhythm. Circadian rhythm helps in deciding human sleep patterns. Circadian rhythm contains an array of genes and the protein that encode various physiological processes throughout the body that controls our physical, mental and behavioral changes, hormone release, body temperature and other important bodily functions. Circadian rhythm is roughly 24-hour cycle that
