MICTURITION REFLEX Physiologically‚ micturition involves coordination between the central‚ autonomic‚ and somatic nervous systems. Central nervous system: Prefrontal cortex‚ precentral gyrus‚ postcentral gyrus‚ hypothalamus‚ amydaloid nucleus‚ periaqueductal gray‚ pontine micturition center Autonomic nervous system: Sympathetic: Lateral horn cells of T10-L2 segments of spinal cord (Preganglionic motor fibres)→Synapse with superior hypogastric plexus→ Hypogastric nerve (Postganglionic motor

Management through Effective Management Control WERNER BRUGGEMAN Performance measurement and performance management are vivid themes in the literature on management control. So‚ it is only natural that we investigate how this literature has contributed to the field of Integrated Performance Management. The purpose of this chapter is to describe how management control systems can be used to effectively manage company and business performance. First‚ we define the scope of management control and describe

accordance with University regulations. Abstract The mechanisms that regulate cellular senescence‚ organismal ageing‚ and species-specific lifespan depend on a synergy of pathways that are multifactorial and extremely complex‚ though not yet completely understood. Recently‚ the development of new molecular techniques has elucidated‚ at least in part‚ the primary pathways involved in ageing. In parallel with the search to uncover the factors that control ageing is the endeavor to discover methods of extending

keep it at the set point. All homeostatic mechanisms use a feedback loop to inform the body about any changes that occur externally or internally. There are two different kinds of homeostatic mechanisms: a positive feedback mechanism and a negative feedback mechanism. Positive feedback mechanisms boost physiological processes and amplify the system’s action to move the system away from the equilibrium state so it is more stable. Negative feedback mechanisms‚ on the other hand‚ maintain equilibrium

Ceftriaxone sodium is a broad-spectrum bactericidal cephalosporin antibiotic. Ceftriaxone is active in vitro against a wide range of Gram-positive and Gram-negative organisms‚ which include β-lactamase producing strains. Ceftriaxone is indicated in the treatment of the following infections either before the infecting

According to (Wolfinger 2008)‚ the people from impoverished families often pregnant at an early age because they lack alternatives‚ such as opportunity for higher education. Socioeconomic status that does not provide any alternative to young girls directs them to early pregnancy. Similarly‚ (Ono 2008)

particles‚ mucus clearance is an essential mechanism to remove the foreign particles‚ such as dust‚ bacteria‚ viruses and other potential pathogens‚ and to keep our airways and lungs clean and free of obstruction. An important mechanism for clearing mucus involves moving water across the membrane‚ out of the cell‚ into the mucus. This movement of water is a result of chloride and sodium transport across the membrane. This method‚ along with other mechanisms is what ensures fluidity of the mucus‚ resulting

The Basic Mechanisms of Homeostasis Overview of homeostasis The term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’. It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits;

Mechanism description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric
