2 weeks after Spring Break (edited)

• Tuesday 3/29:  Neural development:  growth of neurons, synapses, pruning, plasticity, strokes.  Parts of the brain and their functions.  Brain research.  The pupil reflex.  Brain part worksheet.  Read A1 and A2.
• Thursday 3/31:  More on brain function.  Perception of stimuli:  olfactory, the human ear, and the human eye.  Read A3.
• Monday 4/4:  Dissect cow eyes.  Innate and learned behavior.  Reflex arcs, bird song, reflex conditioning.  Read A4.
• Wed 4/6:  Excitatory and inhibitory neurotransmitters.  Psychoactive drugs, anaesthetics, drug testing, and drug addiction.  Read A5 and A6.  Study Ethology over the week-end!!  Paper 3 will be on Wed 4/13.
• Mon 4/11:   Many examples of animal behavior!   Great tit, salmon breeding, synchronized oestrus, blackcap migration, vampire bats, shore crabs, birds of paradise, blue tits.
• Wed 4/13:   Review!!  Review for both Paper 3 and general material.
• Fri 4/15:  Paper 3.  We will take Paper 2 on Tuesday 4/19 and Thursday 4/21
• Tues 4/19:  Paper 2 Part A!  There is a large data-based question and several questions each from 3 topics from the syllabus.
• Thurs 4/21:  Paper 2 Part B. Pick 2 sets of 3 questions out of a choice of 3 sets of 3 questions.  Write everything you know that addresses the question.  You get points for things that you say that match up with the answers on the markscheme.  You do not get marked down for incorrect information, but you do get minimal extra points for writing clearly.
• Mon 4/25:  Take Paper 1 and go over Paper 3.  Paper 1 is 40 multiple choice questions across the whole syllabus.
• Wed 4/27:  Go over Papers 2 and 3.  More review

Nerve Notes from 6.5 (start on Monday 3/14 and continue after test 3/16).

1. What 2 systems of the body are used for internal communication?
2. What does a neuron do and about how many does the human body have?
3. Draw and annotate a diagram of a neuron with dendrites, cell body, axon, and motor end plates.
4. Describe how a cell gets a myelin sheath, and explain what it does to the rate of conduction (include nodes of Ranvier).
5. Explain how neurons generate a resting potential and state what the typical resting potential is in millivolts (mV).
6. Outline the process by which a neuron becomes depolarized (give a value too) and then repolarized.
7. How is an action potential propagated along the axon of a neuron?
8. What is a synapse?
9. List the steps involved in a synaptic transmission.
10. Outline the secretion and reabsorption of acetylcholine by neurons at synapses.
11. What do neonicotinoids do and why have they been in the news around here when it comes to bees?

6.6 Notes to do after Movement/Kidney Test

1. What is a hormone?
2. What does it mean to be in homeostasis?  What are some substances/quantities that need to be kept in homeostasis in your body?
3. Insulin and glucagon:  from where are they secreted?  how do they control blood sugar levels?
4. What are the causes and treatments of type I and type II diabetes?
5. Thyroxin:  from where is it secreted?  what is unique about the molecule?  what does it control?  what are signs of hypothyroidism?
6. Leptin:  from where is it secreted?  what does it act on? what does it control? what does it have to do with obesity?  (read the research!)
7. Melatonin:  from where is it secreted?  what does it control? how is it controlled?  How can it be used to treat jet lag?
