PYC 1501 ASSIGNMENT 1

Question 1 Answer: The correct answer is 1 To answer this question correctly you need to understand impulse conduction in the human nervous system. Human behaviour is based on impulse conduction therefore, statement A is correct. Individual differences in people’s behaviour can result from things going wrong during impulse conduction. Differences in the efficiency of impulse conduction will also result in behavioural differences. Therefore, statement B is correct. Sensory energy has to be converted into electrochemical energy in order to be conducted as a nerve impulse therefore, statement C is incorrect. Impulse conduction is the process that allows the passage of information (or communication) from the outside and inside environments to the brain, as a result statement D is correct. Statement E is also correct because impulse conduction depends on the presence or absence of neurotransmitters. Given that statements A, B, D and E are correct, option 1 is the correct answer. Question 2 Answer: The correct answer is 4 Although the strength and speed of an impulse is constant in a particular neuron, it can vary with nerve fibres of diffe
