3.In the United States only 6.2% of physical therapists are Hispanic. In fact, the percentage of Hispanics working in any
nics working in any other health profession is similar. These figures can be discouraging to aspiring health care professionals that are Hispanic. The number of Hispanic health care professionals will inevitably continue to increase over the years and I want to be a representation for my community. I want the young aspiring Hispanic health care professionals in my community to know that someone just like them is capable of anything. I always knew I wanted to work in the health care industry ever since I was a kid. I always idolized doctors, dentists, nurses, etc. It has always been a dream of mine to end up working in a job where I can help people.
It was not until my senior year of high school that I knew for sure I wanted to be a physical therapist. As I started thinking about what career path in the health care industry aligned the most to my hobbies; I concluded that physical therapy was the career I wanted to pursue. The reasons were simple, my favorite activity is going the gym, I like staying active, and I enjoy learning about the human body.
During my first experience in a physical therapy setting, I was amazed that light resistance exercise can help someone recover from an injury or relieve chronic pain. Many of the patients I saw during my time were patients that recently got a knee replacement. The program the physical therapists created involved strengthening the leg muscles and supporting muscles of the lower body. It illustrates that exercise can be a form of medicine. I observed many patients during my observation hours, but one patient will always be in my memory. The patient was an older lady who broke down in tears of joy and said, "Today I woke up so happy because I had no pain." The way she said it warmed up my heart so much, I had an insane feeling of joy I never really experienced. That moment will always be something I think of when I need motivation to keep going. I want to relive that experience from the physical therapist's point of view one day.
6.I just need someone to look over my paper for anatomy and to just let me know what I need
t or add. I'll attach the questions, my rubric, as well as my answers I made. It would really help me out please.
1.) Choose two somatosensory receptors. Please include a description of each receptor, what they sense, and which part of the brain processes the information from the receptor.
2.) Provide a discussion of the thyroid gland. Include the following:
Description of the thyroid gland's structure and location.
Description of the cells of the thyroid gland.
Description of the hormones secreted by the thyroid gland and their functions.
Description of how thyroid hormones are controlled by hormones secreted by the hypothalamus and anterior pituitary gland.
Description of how the feedback system works in the cases of high or low thyroid hormone levels.
3. Describe the cardiac cycle. Include descriptions of the 3 phases, the pressure changes in each of the heart's chambers, valves are open and closed, and blood flows during each step.
My answer: 1.) Exteroceptor - receives external stimuli from outside of the body. An example, the skin (Thermoreceptors) detects the temperature of the outside area of the body.
Interceptor - receives stimuli from inside of the body. An example would be blood pressure as well as blood oxygen levels.
2.) Thyroid Gland is located near the front lower part of the neck, beneath Adam's apple. Its structure includes Thyroid Epithelial that form follicles filled with colloid - a protein-rich reservoir of the materials needed for thyroid hormone production. The cells are responsible for releasing hormones that control metabolism (Energy levels). The thyroid gland releases triiodothyronine (T3) and thyroxine (T4). These hormones regulate weight, energy levels, internal temperature, skin, and growth. When the hypothalamus and pituitary function well, they can detect when hormone levels are low, which causes them to produce more TRH and TSH, which stimulates the thyroid to produce hormones. When the hormone levels exceed their limit, they then have less TRH and TSH, which results in reduced hormone production by the thyroid. Feedback is when a product feeds back into its initial cycle. The Feedback includes both positive and negative feedback. Positive Feedback is when a product provides back to increase production: an example, milk production by a mother for her baby. As the baby suckles, nerve messages from the nipple cause the pituitary gland to secrete prolactin. Prolactin, in turn, stimulates the mammary glands to produce milk, so the baby suckles more. Which causes more prolactin to be secreted and more milk to is made. Negative Feedback is when a product feeds back decreases production; it brings down show if they increase past their limit. It also controls insulin secretion by the pancreas.
3.) The Cardiac Cycle takes place from the beginning of a heartbeat to the next. It contains two periods: One is when the heart muscle relaxes and refills with blood, called diastole, following a time when it begins contraction and pumping of blood, systole. Once emptied, the heart then relaxes and expands to receive another inrush of blood coming back from the lungs and other areas of the body. The atrioventricular valves remain open while the semilunar valves are closed. During the middle part of the diastole, a small amount of blood flows into the ventricles. The blood flows from the veins and passes the atria fills the ventricles. The pressure in both ventricles is close to zero as a result.
7.students are expected to research and compose a paper based on the application of concepts and theories examined in class.
ies examined in class. This paper is not a literature review, though a literature review is part of your work. As this course takes place in a compressed timeline, I provided some suggestions for research topics. Feel free to use one of these as a springboard or propose your own.
At the end of the second week of class, students submit a three-page research paper prospectus. A research prospectus is a preliminary plan for conducting a study. This is not a detailed and technical research proposal, but rather, an analysis of the issues likely confronted in such a study. In essence, it is a preliminary proposal of work.
Research Paper Prospectus Elements
To complete the Research Paper Prospectus, consider the following elements. While the prospectus is limited to three pages of body content, remember, students must cover each of these areas as relevant to the plan for research:
Research Problem. What is the research problem? A problem is a situation when left untreated, produces a negative consequence for a group, an institution, or a(n) individual(s). What makes it a problem? For whom? Who says so?
Assumptions. On what assumptions is the work based? Which assumptions are verifiable in literature? Which assumptions are speculative?
Theoretical Issues. What theoretical issues arise from the study? For example, "theoretically," how is the problem and suspected results explained to other scholars? Is there a behavior view? A social systems view? Are there other theoretical orientations to consider in the study's design?
Literature Review. What, in general, does the literature say about the topic? While more development is expected for the final paper, a review of major theories, research, and writers in the field is needed.
Research Questions. Based on the problem, what are the research questions to be answered? How and why will answering the questions contribute to solving the research problem? Remember....a research question can only be answered with empirical data or information.
General Research Plan. In general, what research is necessary to answer the research question. What kind of data is needed? Specify the type, such as surveys, observations, or interviews. Who is to be studied and why? How is the data reduced and made sense of? How is the quality of the data assured?
Anticipated Difficulties and Pitfalls. What kind of difficulties and pitfalls are expected in a study of this nature? What can be done to prevent them or minimize their effects?
Anticipated Benefits. Who will benefit from the fact this research is undertaken? How? Why? Who might be disturbed by this proposed study? How? Why?
Paper Format Requirements
The Research Paper Prospectus is presented in standard APA 7 format, with a cover page, running head, body, and references list. The cover page and references do not count toward the three-page requirement. The body uses headers and in-text citations in the manner prescribed by APA. Students should include any references they know at the time they submit the prospectus, though it is expected the references may change or increase in number. Full and complete adherence to APA is required.
As APA format is the rule, remember the formatting rules shown on the Sample Paper (Links to an external site.):
Times New Roman, 12pt
1" margins on all sides
Double spaced, with extra line spaces removed (see below)
Page numbers in the upper right
Two spaces after concluding punctuation
150-250 word abstract with keywords
APA-style in-text citations and quote format. Use the Purdue OWL in-text citation information (Links to an external site.)to help you.
