Unit 3 vocabulary Biological Psychology- a branch of psychology concerned with the links between biology and behavior. neuron- a nerve cell sensory neurons- neurons that carry incoming information from the sensory receptors to the brain and spinal cord motor neurons- neurons that carry outgoing information from the brain and spinal cord to the muscles and glands. interneurons- neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs dendrite- the bushy, branching extensions of a neuron that receives messages and conduct impulses toward the cell body. axon- the extension of a neuron, ending in a branching terminal fibers, through which messages pass to other neutrons or to muscles or glands. myelin sheath- a layer of fatty tissues segmentally encasing the fibers of many neurons, enables vastly greater transmission speed of neural impulses as the impulse hops from one node to the next action potential- a neural impulse a brief electoral charge that travels down an axon. threshold- the level of stimulation required to trigger a neural impulse synapse- the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron. the tiny gap at this junction is called the synaptic gap or synaptic cleft. neurotransmitters- chemical messengers that cross the synaptic gaps between neurons. when released by the sending neurons, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse reuptake- a neurotransmitters reabsorption by the sending neuron nervous system- the body’s speedy electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems. central nervous system- the brain and spinal cord peripheral nervous system- the sensory and motor neurons that connect the central nervous system to the rest of the body nerves- bundled axons that form neural cables connecting the central nervous system with muscles , glands, and sense organs somatic nervous system- the division of the peripheral nervous system that controls the body’s skeletal muscles. Also called the skeletal nervous system autonomic nervous system- the part of the peripheral nervous system that controls the glands and the muscles of the internal organs. it’s sympathetic division arouses; its parasympathetic division calms sympathetic nervous system- the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations. pstsdympathetic nervous - the division of the autonomic nervous system that calms the body, conserving its energy reflex- a simple, automatic response to a sensory stimulus, such as the knee-jerk response. endocrine system- the body’s slow chemical communication system; a set of glands that secrete hormones into the bloodstream hormones- chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues. adrenal glands- a pair of endocrine glands that sit just above the kidneys and secrete hormones that help arouse the body in times of stress. pituitary glands- the endocrine system’s most influential glands. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands. lesion- tissue destruction; a brain lesion is a naturally or experimentally caused destruction of a brain tissue. electroencephalogram- an amplified recording of the waves of electrical activity that sweep across the brains surface. these waves are measured by electrodes placed on the scalp. computed tomography scan- a series of x ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body positron emission tomography scan- a visual display of brain activity that detects where a…
Chapter 3 – Food Production and the Environment summary
This chapter discusses the prospects of feeding an ever growing human population given the constraints on food production such as converting land into farmland, harming the environment, limited water supplies and many other factors that poses a negative externality on the environment. In order to address these issues without compromising food production and the environment, government intervention and policies need to be put in place to avoid…

Brief review of the main points of the chapter (200 word abstract)
This chapter was largely structured around figure 3.1, which shows the interrelationships among job analysis, job descriptions, job specifications, job evaluation, and the HR functions that are built on these processes. Job analysis is the process of defining a job in terms of its component tasks or duties and the knowledge or skills required to perform them. Job analysis…
In chapter 3, The Journey North, how does Hill’s description of the train journey from London to Crythin Gifford prepare the reader for what is to come in the novel?
In chapter 3, Arthur travels north to Crythin Gifford where a man comes to his compartment and introduces himself as Samuel Daily who shows some interest in the Drablow file but Arthur pretty much ignores him. Hill instantly makes the reader suspicious by the cheerful tone to the journey up north especially after the fog in chapter 2…
Microeconomics – Chapter 3
Competitive Market – a market that has many buyers and many sellers, so no single buyer or seller
can influence the price.
Producers offer items for sale only if price is high enough to cover their opportunity cost.
Money Price – the price of an object that must be given up in exchange for it
Relative Price – ratio of one price to another/is an opportunity cost
1. Want it
2. Can afford it
3. Plan to buy it
Quantity Demanded – amount that consumers plan to…
CHAPTER 3 NOTES
Cost Structure: the proportion of variable costs and fixed costs in an organization.
Variable cost: these costs vary in total directly and proportionately with activity level, but are constant per unit.
Activity level or activity base: measure of what causes or drives variable cost.
Can be a measure of either inputs or outputs.
For many purposes we’ll use output units as the activity base – but not always as time goes on!
EXAMPLES: See Exhibit 3-2.

In the introductory chapter we described IHR managers as
grappling with complex issues:
Manage more activities from a broader perspective,
Be more involved in the lives of their far-flung
Balance the needs of PCNs, HCNs and TCNs
Control exposure to financial and political risks and
Be increasingly aware of and responsive to hostcountry and regional influences.
In this chapter, all of these issues and concerns are…
Key Concept Review (Answers to in-text “Concept Checks”)
1. Wegener believed that the heavy continents were slung toward the equator on the spinning Earth by a centrifugal effect. He was wrong in that belief, but correct in sensing that continents were moving.
2. Where were the tracks through old seabed that the migrating continents might leave? What forces were strong enough to propel continents over long distances?
3. Something is said to be dense if it weighs a lot per unit…
