Central Nervous System – contains the brain and the spinal cord. It serves to connect the sensory and motor fibers within the nervous system thus considered as the "integrating center" for all behavior and bodily functions. Spinal Cord – is the large rope-like segment of nerve tissue extending down the vertebral column, which is approximately as thick as a person’s little finger. Its principal function is to distribute motor fibers to the effector organs of the body and to collect somato-sensory information to be passed on to the brain. Spinal cord is 2/3 as long as the vertebral column and the rest is spinal roots composed of caudal equina. Brain – has an average weight of 3 lbs. and contrains at least 15 billion nerve cells called neurons Major Parts of the Brain   1. Hindbrain Closest to the spinal cord It performs a series of reflex actions such as blinking of the eye and some processes like breathing, heart rate and blood pressure. Parts of Hindbrain ...

What is Neuron/Nerve Cell The basic structural unit or building block of the nervous system The smallest nerve cell is less than a millimeter in size while the largest may be more than a meter in length Nerve cell holds the secret how the brain works Nerve cell has two specialized functions: [1] to receive signal [2] the longer extension is for transmitting signals Acethylcholine – is a neurotransmitter or chemical substance that travels across synaptic gap, stimulates the next neuron, carrying the impulse from one neuron to another Glial cells – are non-neural cells that hold the neurons in place Myelin Sheath – is the covering on the axons of neurons, which insulate them, making the transmission of impulses faster Parts of a Neuron Dendrites – receive impulses and carry them toward the cell bodies. These are short branches of fibers branching out like roots from the cell body Axon – carries impulses away from the cell body toward other neurons. These are...

Sleep Deprivation / Sleep Loss - Being prevented from getting the desired or needed amounts of sleep - Typically causes trembling hands, dropping eyelids, inattention, irritability, staring, increase pain sensitivity and general discomfort (Doran, Van Dongen and Dinges, 2001) - If you lose just one hour of sleep at night, it can affect your mood, memory, ability to pay attention and even your health (Mass, 1999) Normal range of sleep - Majority of us sleep on a 7 to 8 hour per night schedule Sleep hormone - A sleep-promoting substance found in the brain and spinal cord Beta Waves - Small, fast brain waves associated with being awake and alert Alpha waves - Large, slow brain waves associated with relaxation and falling asleep; also occur when you are relaxed and allow your thoughts to drift Non-REM sleep function - Increases after physical exertion and may help us recover from body fatigue REM sleep (Rapid Eye Movement sleep...

The genes uses a chemical alphabet to write instructions for the development of brain and body and the manufacturer or chemicals that affect mental health, learning, emotions, personality traits and everything we do. What is gene? Chains of chemicals arranged like rungs on a twisting ladder There are about 20,000 to 25,000 genes that contain chemical instructions equal to about 300,000 pages of typed instructions (IHGSC, 2004) The chemical instructions program the development of millions of individual parts into a complex body or brain.

Sociology: McDonaldization of Society McDonaldization of Society by: George Ritzer (1993) Rationalization - the way in which traditional, spontaneous, rule of thumb methods of social organization are replaced by abstract, explicit and carefully calculated rules and procedures Mcdonaldization - the process in which the priciples of fast food restaurant are coming  to dominate more and more sectors of society for the rest of the world - the increasing rationalization of the routine tasks of everyday life 5 Dominant Themes of Mcdonaldization Efficiency : choosing of means to reach a specific end rapidly with the least amount of cost or effort Calculability : emphasis onthings that can be calculated and quantified [ quantification : tendency to emphasize quantity rather than quality ] Predictability : rational people need to know what to expect, they wanted to be sure that fun, satisfaction, taste and benefis they receive today will be repeated again Increase Contro...

Sociology: Attitude Towards Cultural Variations 1. Ethnocentrism practice of judging all other cultures by one's own culture based on assumption that one's way of life is superior to all others forms of ethnocentrism            - positive ethnocentrism: school songs, national anthem, pledge to flags/patriotism           - negative ethnocentrism: customs, dress, eating habits, religious beliefs is marked differently from those of dominant group members 2. Cultural Relativism inverse/opposite of Ethnocentrism practice of judging other cultures by his own context 3. Xenocentrism preference the products, styles, ideas, or ideas of someone else's culture rather than of one's own (colonial mentality); Xeno means foreign 4. Cultural Shock when you are confronted with other culture, there is a feeling of anxiety and disorientation 5. Cultural Lag maladaptation maladjustment there is rapid improvement whe...
