A decrease in arterial blood pressure results in decreased baroreceptor firing. The autonomic neurons within the medulla respond to this by increasing sympathetic outflow and decreasing parasympathetic (via the vagal nerve) outflow. Upon standing up‚ there is disinhibition of the sympathetic activity in the medulla so sympathetic activity coming from the rostral ventrolateral medulla increases. These autonomic changes trigger vasoconstriction‚ tachycardia and positive inotropy. These changes increase

Somatic Cell Transfer is a scientific laboratory technology during which there is the fusion of the entire nucleus of a non-reproductive cell (somatic cell) and its entire nuclear DNA content‚ with the cell of a reproductive cell (germ cell) whose nucleus has been removed; called an enucleated cell‚ allowing the host cell to program the inserted nucleus from the somatic cell‚ and then triggering the reproductive cell with its new DNA content to undergo cell mitotic division in a cell culture.

Critically evaluate to what extent the ‘somatic-marker hypothesis’ explains how decisions are made in the face of an uncertain outcome. In mind of Kim Sterelny’s (2007) statement that ‘Human Life is one long decision tree’‚ it is not surprising that there has been a vast amount of research into the process of how we evaluate the desirability of alternative choices and select a particular option. One area of research‚ of particular interest here‚ is Damasio’s Somatic Marker Hypothesis (SMH) (1991) which

Management‚ Somatic Awareness‚ and Body Image Theories; there appears to be someare specific interactions between these theories that should be explored and used to bolster this knowledge and shed new light into aspects of these models that may not have been discovered as of yet. According to Becker and Terror Management Theory (TMT)‚ our mortality and self-esteem are the key motivators in life‚ which begs the question‚ what if individuals had higher or lower awareness of their bodies‚ or Somatic awareness

Compare the somatic and autonomic nervous systems relative to effectors‚ efferent pathways‚ and neurotransmitters released. 3. Compare and contrast the functions of the parasympathetic and sympathetic divisions. ANS Anatomy 4.
