Name:Period:AP Psychology – Guided ReadingUnit 3A – Neural Processing and the Endocrine System1. What is biological psychology?Part 1 – Neural Communication2. Why is it a benefit that there is not much difference between the brains of humans and animals?3. Define neurons.sensory neurons –motor neurons – c. interneurons -d. dendrite -e. axon –f. myelin sheath – How is the myelin sheath related to multiple sclerosis?g. action potential –h. Using the terms ions, resting potential, and selectively permeable, describe the chemical events that allow neurons to fire.i. How do the security parameters changes when a neuron fires (include the term depolarize)? How often can this process repeat?j. What are excitatory signals and what are inhibitory signals?What is threshold?4. What is a synapse? 5. Using the terms neurotransmitters and reuptake, describe the how neurons send information across the synaptic gap.6. How can neurotransmitters influence our motions and our emotions?7. What discovery was made by Candace Pert and Solomon Snyder in regards to neurotransmitters?8. What are endorphins and give an example of what they can do?9. What happens when the brain is “flooded” with opiate drugs such as heroin and morphine?11. What is the difference between an agonist and an antagonist?Part 2 – The Nervous System12. What is the nervous system?13. What is the peripheral nervous system?somatic nervous system –autonomic nervous system –sympathetic nervous system –parasympathetic nervous system –14. What is the central nervous system?a. Approximately how many neurons in the central nervous system?b. What are neural networks?c. Neurons that ____________ together ___________ wire together, helping learning occur.d. What is the spinal cord and how does it work?How do spinal reflex pathways work?What happens if the spinal cord is severed?Part 3 – The Endocrine SystemWhat is the endocrine system?What are hormones?What happens when they act on the brain?How is the endocrine system similar to the nervous system? Different from the nervous system?What are adrenal glands? What aspects of our lives are influenced by the endocrine’s system of hormones?What is the pituitary gland?
