What you will learn:

The liver as a target organ

  • Outline the structure and functions of the liver (including its role in metabolism)
  • Explain what is meant by 'adaptation' and its toxicological significance
  • Explain what is meant by hepatic enzyme induction
  • Explain why the liver is commonly a target organ for toxicity, and how it responds to chemical injury (necrosis, cirrhosis, steatosis, cholestasis and hepatocarcinogenesis)
  • Describe the common indicators of liver injury and how they should be interpreted (e.g. decreased albumin levels, elevated alkaline phosphatase, etc)

The kidney as a target organ

  • Outline the structure and function of the kidneys
  • Describe the filtration, re-absorption and secretion processes and their role in excretion
  • Explain why the kidneys are a common target organ for toxicity
  • Explain the difference between acute and chronic renal failure with specific examples of chemicals which cause this type of effect
  • Describe the approach which is taken in the assessment of renal injury/function and the interpretation of the results

The nervous system as a target organ

  • Outline the structure and function of the nervous system (central nervous system, peripheral nervous system, the cells of the nervous system and the blood brain barrier)
  • List the main cells of the nervous system and their respective roles
  • Describe how information is transmitted within the nervous system (development of action potentials and neurotransmitters)
  • Explain what happens and the synapse and the role of neurotransmitters
  • Describe the ways in which the nervous system can be a target organ for toxicity (including neuronopathy, axonopathy, myelinopathy, interference with chemical transmitters)
  • Outline the approach which is taken to assess the potential neurotoxicological effects (including developmental neurotoxicity)
