Energy and Homeostasis - Research Paper Example The lipostatic model is concerned with the fat molecules in the body that determine the need of food and energy, and its regulation. The intake and termination of meal may be dependent on several internal and external factors that are studied as the signals. The number and quantity of meals generally depend and vary with different species of animals. It is not fixed and different species have different mechanisms that trigger the need for food intake and how they maintain their balance of energy (Woods et al, 1998, pp.1378-1382). The neurohumoral system is mostly responsible for the process of energy homeostasis in the body. Hormones play a major role in this regard. The central nervous system (CNS) of the body has direct effects on the balance of energy in response to the fat molecules within a body. Leptin and insulin are two major signals that function in association with the CNS. The catabolic response to leptin administration in the body determines the gain or loss in weight as well, along with the rates of metabolism. Considering the central effector pathways, the study reveals that the regulation of energy homeostasis is largely dependent on the hypothalamus containing neuroal systems. Depending on the level of fat, pathways like ARC-PVN NPY might be activated. Also, hormones such as glucocorticoid might be secreted in the process as an effect of NPY. Considering the central catabolic systems, the expression of proopiomelanocortin genes is restricted for ARC neurons that lead to parts necessary for en ergy homeostasis. Thus melanocortins have a significant role to play in the process of regulation (Woods et al, 1998, pp.1378-1382). The corticotrophin releasing hormone is also another highly essential component of the process of energy homeostasis in the body. Food intake may be reduced with the implication of this hormone thus leading to loss of body weight. Also, these hormones may have a direct linkage

Planning and Preparing to Teach - Essay Example In the process of going through the discussion, appropriate teaching and learning approaches will be tackled in details followed by identifying some strategic ways on how the paramedics can deliver inclusion sessions to motivate the learners to learn the best technique in managing the patients’ airway. To meet the curriculum requirements, the use of teaching and learning strategies as well as important resources will be discussed one by one. The paramedics has a huge role and responsibilities to meet when teaching the students to conduct basic life support such as the cardiopulmonary resuscitation (CPR) and first-aid techniques when dealing with emergency and life-threatening cases (Hazinski, et al., 2004). Specifically the blood loss that may occur when the victim is seriously injured can lead to cardiac arrest (The American Heart Association in collaboration with the International Liaison Committee on Resuscitation., 2000). This situation requires immediate call for ambulance, CPR, early defibrillation (if necessary), and early advanced life support to prevent brain death (Hazinski, et al., 2004; Hickey et al., 1995). By encouraging the students to perform immediate action, paramedics will be able to increase the survival rate of the victim (Robertson, 2000). Obstruction in the patient’s normal airway functioning is a life-threatening scenario since the lack of oxygen that flows in the blood that flows through the human body can lead to end-organ damage, hypoxia, hypoxemia, and high mortality rates. (Eddleston et al., 2006; Levy, 2005; St. John, 2004; Ayus & Arieff, 1995) For this reason, it is crucial on the part of the paramedics to pay close attention with the patients’ breathing pattern during the assessment stage. Given that the patient shows signs and symptoms that there is an obstruction to the patients’ airway, paramedics should immediately establish the patient’s airway as part of the initial management
