How the Body Works: Overview of Organ Systems Posted by Dr. Ben Kim on Nov 25, Natural Health Care If you want to be relatively free of the fear of not knowing enough about your health that you have to rely on others to make big decisions for you, it's critical that you take some time to learn about how your body works. The goal of this series of articles is to give you a broad look at the major organ systems in your body and how they work together to keep you well.

Organization and Evaluation of Brain Function This module introduces the general external topography of the brain. To illustrate the relationship between specific behaviors and brain function, the module begins by showing a racecar driver exercising his skill, and then presents graphic illustrations of the internal activity of his brain.

The Effects of Hormones and the Environment on Brain Development This module presents some startling and significant findings relating to the effects of sex hormones on brain development.

Beginning with in utero photography and then visiting an animal laboratory, this module shows how Dr. Marian Diamond's ground-breaking research has revealed structural differences in the brains of men and women, as well as factors influencing these differences.

Social Influences Shifting from the biological focus of the previous module, this segment shows how social factors affect gender-specific behaviors.

Mother-child interactions are shown, illustrating typical differences in how male and female children are treated, and how this treatment affects gender identity, roles, and expectations, and perceived differences in ability.

Intelligence and Culture The issue of cultural bias in testing is explored in this module, presenting Judy Kearins's work with Australian children. Theories of cultural influence on cognitive processing and the shaping of the brain are suggested as explanations for tested differences in ability.

The Divided Brain This module begins with graphic representations of the cerebral hemispheres' specialized functions. It continues with a description of the brain's asymmetry, showing diagrams of how the two halves communicate.

The extreme case of a patient who has undergone split-brain surgery for treatment of epilepsy illustrates the role of hemispheric organization in sensory perception and verbal skills.

Broca's and Wernicke's Areas The left hemisphere is dominant in this module on language and the brain.

Relationships between specific brain areas and verbal processing are shown through the historic example of Dr.

Paul Broca's brain-injury patient. The patient's preserved brain is subjected to CAT scan analysis, which shows correspondence between the damaged area and the patient's documented difficulties with language comprehension.

Brain Anomaly and Plasticity: Hydrocephalus Hydrocephalus, a childhood disorder of excess fluid in the brain, illustrates brain plasticity — the brain's amazing ability to rebound after injury.

While patients with this disorder experience compression and destruction of brain tissue early in life, many are able to function normally later in life, after their brains have compensated for the loss. Elementary Concepts This module depicts the original pioneering research on how the brain's visual systems transmit and encode information.

Researchers at the University of California, Berkeley, present their work on the visual cortex of the monkey using x-ray images. Two Nobel laureates also recount their serendipitous discovery of "feature detector" cells in the striate cortex that respond only to stimuli of certain sizes or direction of movement.

Perception This module concentrates on higher visual areas beyond the striate cortex, addressing the questions of when seeing becomes perception and where it all takes place.Synaptic transmission begins when one brain cell releases a neurochemical into the synapse.

Parietal Lobe

The transmission, however, is not complete until that neurochemical binds with a receptor on the postsynaptic, or receiving, neuron. Researchers have learned that receptors are equally as important as the.

The brain lymphatic drainage system may include perivascular pathway, glymphatic system, olfactory/nasal and meningeal lymphatics.

• The brain lymphatic drainage system maintains homeostasis of brain and participates in immune responses and surveillance. Dec 08,  · The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body.

Parietal Lobe. The parietal lobe houses the functions that perceive and process somatosensory events. It extends posteriorly from the central sulcus to its border with the occipital lobe (Fig.

).

Developed from the original series The Brain, these flexible resources offer extensive footage and research into the inner workings of this amazing human organ, including findings on Alzheimer's disease, schizophrenia, autism, Parkinson's disease, and many other topics.

The modules are appropriate for use in general and advanced courses in . A paradigm (パラダイム, Paradaimu?), also known as an optima (オプティマ, Oputima?), is a combination of roles in Final Fantasy XIII and Final Fantasy XIII The player can preset up to a maximum of six paradigms when outside battle.

During battle the player can freely switch between the preset paradigms.
