Abstract

The literature defines hypertension as a medical condition experienced when the systolic blood pressure (BP) is equal or greater than 140 mm Hg or when the diastolic blood pressure is equal or greater than 90 mm Hg. Additionally, it offers a description of systematic, cellular, as well as molecular causes of hypertension. High blood pressure within the arteries is referred to as systemic hypertension (SH). The primary role of the systemic arteries is the transportation of oxygenated blood from the heart to the tissues of the body. The constriction of the arterioles (small arteries) is responsible for the high ...

Describe the underlying pathology of COPD and the common pathological characteristics of the condition. Discuss the impact these pathological changes have on normal function, including how alveolar ventilation might be different in Mr Wenham compared to a normal individual. The hallmark pathological attributes of chronic obstructive pulmonary disease (COPD) are one, poorly reversible airflow obstruction and two, a progressive atypical inflammatory response within the lungs. The abnormal inflammatory response denotes the responses of the innate and adaptive immune systems to long-standing exposure to noxious gases and particles especially cigarette smoke. Notably, all cigarette smokers have some degree of inflammation ...

Based on the initial symptoms, the patient most likely suffers from hypothyroidism or low thyroid hormone disorder. Further clinical tests and an examination of the family’s medical history reveals that the particular disorder could be Hashimoto’s disease; also called Hashimoto thyroiditis. Hashimoto thyroiditis is classified as an autoimmune disease. In autoimmune disease, one's immune system attacks the body’s tissue specifically the thyroid gland (Skugor & Wilder, 2006, p.2). By attacking the thyroid gland, the disease reduces the gland’s ability to produce thyroid hormones of substantial quantity. This condition leads to hypothyroidism. Thyroid hormone deficiency presents with ...

Abstract

A 'mirror-tracing task' (or mirror-tracing test) is a psychological test used to measure a variety of functions such as learning, transfer of information from one brain hemisphere to the other, and other perceptual/motor skills. In the test, two hypotheses were formulated in a bid to understand the concept of spatial perception, transfer of abilities and gender differences. On the first hypothesis, Continuous exposure to the mirror-tracing test will lead to improved mirror tracing skill; we needed to look at the influence of practising on the mirror tracing skill. 243 subjects were continuously exposed to the test for seven days and the results ...
