We all take advantage of sleep and think of it, at times, as a luxury more than a physiological and psychological necessity. Edwards, O’Dreiscoll, et al, in their paper over Aging and Sleep: Physiology and Pathophysiology, simply defined sleep as a natural state characterized by a reduction in voluntary motor activity (skeletal muscle movement) but not involuntary activity (heart, lungs, organs, etc.), and a decreased response to stimulation and stereotypic posture that is both reversible and…

TAQ 1 Explain the term Homeostasis. The term homeostasis is derived from two Greek words; homios meaning ‘the same’ and stasis meaning ‘steady’. It refers to the processes by which the body and internal cells seek to constantly maintain an internal state of balance and equilibrium even when faced with external environmental changes. This is achieved through either positive or negative feedback loop controls associated mainly with the endocrine and nervous systems. Principal homeostatic…

Changes in the hormone balance are more common with bilateral cases of ONH and include thyroid, pituitary, adrenal, anti-diuretic hormone and growth hormone deficiencies (Kaur et al). Approximately 75 percent of patients have hypopituitarism due to hypothalamic dysfunction and nearly 33 percent have hyperprolactinemia. Endocrinopathies such as these…

Changing Relationships Overview of physiological and cognitive changes Adolescence begins with puberty, the time when one develops primary and secondary sex characteristics. Primary sex characteristics are the changes in the organs concerned with reproduction, and secondary sex characteristics involve changes in features that distinguish the two sexes from each other, but are not involved in reproduction. (Lumen Learning 2017) The initial surge of hormones that start the puberty process,…

These adolescent girls have shown reduced bilateral anterior insula and right striatal grey matter volumes when compared to healthy controls. By comparing the analyses between female and male conduct disordered youth we are able to see the main effect of diagnosis on right amygdala volume. This study also allowed us to observe differences between the sexes, which included the bilateral anterior insula interaction of this diagnosis. Researchers were able to conclude that…

The arrow attack stimulates increased secretion of pituitary hormones, and the Sympathetic Nervous System is immediately activated. The patient might have been prompted to respond immediately by fright mechanism to avoid another attack. The Autonomous Nervous System entirely controls this response. More energy…

Hypertension or otherwise known as High blood pressure is defined as a high force of blood pushing on the walls of the arteries during the flow of blood. Blood pressure is measured as the heart pumps and as the heart fills and rests in between heartbeats. This is called systolic pressure and diastolic pressure. They are both measured in milliliters of mercury. Those with a systolic pressure of over 120 and a diastolic pressure of above 80 are clinically defined as having prehypertension and…

With little ability to compare her own female experiences to those of her somewhat absent mother, Carolyn worked closely with her father, husband and friends to inform herself on life changes she would have to make to…
