Neural Communication- the way in which the brain and the body communicate with each other
The Impact of Neurotransmitters- neurotransmitters help us influence motions and our emotions for example acetylcholine is one of the best understood neurotransmitters and it enables muscle action, learning and memory
Impact of drugs/chemicals on n. communication-they may cause the brain to stop producing its own natural opiates, they affect the communication at the synapse often by either exciting or inhibiting neurons from firing
Nervous System- the body's speedy, electrochemical communication system, consisting of all the nerve cells of the peripheral and central nervous systems.
central nervous system(CNS)- the brain and spinal cord
peripheral nervous system(PNS)- the sensory and motor neurons that connect the central nervous sytem to the rest of the body.
nerves- nural "cables" containing many axons. These bundled axons, which are a part of the peripheral nervous sytem, connect the central nervous system with muscles, glands, and sense organs.
sensory neurons- neurons that carry incoming information from the sense receptors to the central nervous system.
interneurons- central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs.
motor neurons- neurons that carry outgiong information from the central nervous system to the muscles and glands.
The Peripheral Nervous System- it has two components, somatic and autonomic.
somatic nervous system- the division of the peripheral nervous system that controls the body's skeletal muscles.
autonomic nervous system- the part of the peripheral nervous system that controls the glands and the muscles of the internal organs. Its sympathetic division arouses and its parasympathertic division calms.
sympathetic nervous system- the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations.
parasympathetic nervous system- the division of the autonomic nervous system that calms the body, conserving its energy.
The Central Nervous System- the central nervous system enables our humanity, our thinking, feeling, and acting.
the central nervous system spinal cord- an information highway connecting the peripheral nervous system to the brain.
reflexes- our automatic responses to stimuli.

How does neuroscience help or hinder the credibility of psychology as a science?
Neuroscience helps the credibility of psychology as a science because it deals with the brain and the body as well as the different parts and systems, all of which is included in biology. We all know that biology is a science and with the connection with the body and brain to both biology and psychology it is obvious that psychology can be a science.
How do the brain and body work together to explain how humans think, feel and act?
Separate the brain and the body would be useless but when used together they create human life. The medulla controls the heartbeat and breathing, without the heartbeats and breathes there would be no life. The thalamus allows the body to have its five senses, seeing, taste, and touch, hear and feeling. The cerebellum enables non verbal learning and memory and coordinates voluntary movement. For example, if this part of the brain was injured one would have trouble shaking hands. The limbic system links emotions such as fear and anger and basic motives such as food and sex. The limbic system controls the body’s hormones and without the brain there would be no motivation for sex or hunger. If there was no cerebral cortex, a person could be compared to a television that has its power cord cut. The cerebral cortex does all motor and sensory function in the body so without it we would not be able to move. Every part of the brain plays a crucial role in the life of a human such as how we think feel and act.
How do gender roles play a role in how we study human beings and how they think?
Gender plays a huge role in how we study human beings and how they think. Researchers have shown that between the different gender roles there are many differences and distinctions. Some of these distinctions are what we dream, in how we express and detect emotions, and in our risk for alcoholism, dpression and eating disorders. Although men and women have very many distinctions they also have similarities such as they learn to walk at about the same age.
How does culture play a role in how people behave?
Culture also plays a huge role in how people behave. How people are raised and brought up plays a significant role in how they behave. For example if someone is raised in a culture that is very proper then they are going to behave like that the rest of their lives. Also baised on their culture someone could greet you in different ways. Some cultures people bow when they greet people and others people just wave to each other. But although our cultures seperate how we behave there are some similarites between cultures such as how school kids greet their teachers. Schoolchildren greet their teachers with respect no matter what culture they are from.

hmm...interesting point about school children greeting their teachers with respect regardless of the culture. Many countries around the world are flabbergasted at the way that American kids treat their teachers!
