What is psychology? The scientific study of behavior and mental processes Development of psychology as a science Wilhelm Wundt founded the first psychology laboratory. Student of Wudnt ’s‚ E.B. Titchner named Wundt ’s approach structuralism. William James gave field an "American Stamp‚" invented functionalism Contemporary approaches to psychology Biological Approach (focus on the body) Neuroscience Behavioral Approach (behavioral responses and their environmental determinants) Psychodynamic

simultaneously and very quickly. The brain itself requires extremely fast speeds to operate at even at the simplest level. How do the biological tissues of our body support such rapid coordination of the brain‚ limbs‚ and sensory input? They do so with nervous system tissue that imitates electrical wiring. A series of photomicrographs and schematic illustrations show myelinated nerve fibers. Panel A is an illustration of a single neuron with major structures labeled. Panel B is an illustration of a cross

people) Normally‚ neurons in the central nervous system (the brain and spinal cord) cannot regenerate injured nerve fibers‚ limiting people’s ability to recover from brain or spinal cord injuries. Repair of the central nervous system and restoration of voluntary motor activity through axonal re-growth has long been considered impossible in mammals. Over the last decade‚ numerous attempts proved disappointing overall. While repair of the central nervous system has long been considered impossible have

Unit 5: Anatomy and Physiology Topic: Types of tissues Date: 09/06/2015 Objectives : Exploring four types of tissues. and Comparing four types of tissues : Nervous‚ Connective Epithelial‚ and muscular tissues. From Tissues to organs Cells combine to form tissues and tissues combine to form organs. Cells combine to form four primary tissues: - Epithelial tissue - Connective tissue - Muscle tissue - Nerve tissue BACKGROUND:A tissue is a group of cells that have a similar

They are many different areas in the field if neuroscience. Neuroscience deals with the five senses‚ anything connected to the nervous system‚ the brain‚ anything that sends information to and from the brain‚ etc. Many of these things go from simple ideas and concepts to the complex coding

HUMAN AS A COMPLEX ORGANISM The human body is a complex system of cells‚ most of which are grouped into organ systems that have specialized functions. These systems can best be understood in terms of the essential functions they serve: deriving energy from food‚ protection against injury‚ internal coordination‚ and reproduction. The continual need for energy engages the senses and skeletal muscles in obtaining food‚ the digestive system in breaking food down into usable compounds and in disposing

counterbalance the additional adrenaline‚ the brain produces a neurotransmitter called GABA which is the most important inhibitory neurotransmitter in the central nervous system. It helps the neurons mend after transmission‚ and decrease anxiety and stress. GABA is a significant mood modulator and has inhibitory effects upon the nervous system. (NeuroGenesis‚ 2011) Glutamate is the major excitatory neurotransmitter in the brain which is necessary for learning and memory. When glutamate is at a low level

The nervous system is affected because the motor neurons will stop working which makes it harder for the muscular system to do its job. The nerve cell make an important chemical called dopamine which sends signal to the brain for movement without the nervous system the body will be hard to move because if the dopamine can’t end the signal the body can’t move which can be very difficult. The muscular system permits movement and circulate blood if the muscular system stop working it can

receptors on the membrane of the neighboring cell. This stimulus causes positive sodium ions to rush across the cell membrane‚ stimulating the second cell. If the stimulation exceeds the cell’s threshold‚ a new impulse begins. 7. The autonomic nervous system regulates activities that are involuntary. 8. I don’t know. I’m really tired. Maybe. 9.

Lemon Grass Lemon Grass is a magical herb that is very useful in many ways. It have lots of benefits if uses in right direction and proper way. A 2005 study by Ben Groin University of the Negev found that the oil from lemon grass caused cancer cell death. According to the Sun Star Network‚ lemon grass may have diuretic properties and can help with digestion. Lemon grass can also help you lose weight‚ particularly when mutual with a well diet and regular physical movement. Health Benefits of Lemon
