Chapter 3 The Biological Bases of Behavior Communication in the Nervous System * Nervous Tissue: The Basic Hardware * Neurons are individual cells in the nervous system that receive‚ integrate‚ and transmit information. * The soma‚ or cell body‚ contains the cell nucleus and much of the chemical machinery common to most cells. * Dendrites are the parts of a neuron that are specialized to receive information. * The axon is a long‚ thin fiber that transmits signals

Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. Neurons are electrically excitable cells found in the nervous system‚ which is mainly responsible in the transmission of information between the neurons and the cells

Investigating the physiological response of anxiety through general knowledge and math questionnaires‚ with a focus of inducing anxiety through music. The aim of this study was to investigate the physiological effects associated with math anxiety‚ with a further aim to explore this in relation to tense music exposure. It was hypothesised that a maths questionnaire would produce a significantly higher anxiety response than a general knowledge questionnaire. It was also hypothesised that exposure

brain that plays a role in whether we feel hungry or full. What about blood can trigger this region to make us want to eat? The hypothalamus is a region of the brain that plays a role in hunger as well as satiety. When we have not eaten for a long period of time‚ the amount of nutrients in the blood begin to decline. This drops stimulates the feeding center in the hypothalamus and signals us to eat. When the nutrient blood level of the blood begins to rise‚ the satiety center is activated and our desire

Our skin helps to control body temperature known as thermoregulation. The thermoregulation as one of the process in homeostasis that both of skin and hypothalamus receptor are involved. The hypothalamus will send a signals in skin which of the Krause (hot) or Ruffini (cold) are appropriately activated ‚ and sweat glands is activated to release sweat so that the temperature in the body will appropriately response back to normal

Biology and Behavior Animal testing is not a problem in today’s society because it is beneficial to humans. It seems unethical to put animals through such pain and torture‚ but if we stopped it completely there would be a large amount of human lives lost. How could this be? The further advancements in medical and technological science is inevitable. Therefore‚ if the testing must be done to learn more about the brain and body‚ which species (animals or man) seems expendable for such testing. The
