    Sleep - Part 1

    Monday, October 19, 2015

    In spite of the importance of sleep to our mental, emotional, and physical well-being, our knowledge of the physiology of sleep is rather limited. We know from personal experience that lack of sleep leads to reduced mental alertness, diminished mental and physical performance, mood changes, and many other symptoms, all of which appear to be readily "cured" by getting "enough" sleep. Yet, how much sleep one needs is highly variable among individuals, and the reason for this variability is not at all clear. Human and animal studies are only beginning to elucidate the physiological factors and processes that are influenced by sleep deprivation.

    Neuronal Action Potential - Part 5

    Wednesday, September 30, 2015

    Excitable cells of the nervous system (i.e., neurons) generate nervous impulses. Nervous impulses are the electrical signals by which neurons talk to one another and also to other cells of the body. The nervous impulse is referred to as the action potential. An action potential is a brief (only a few milliseconds) reversal of the membrane potential (Vm). At rest, the Vmof a neuron is around −70 mV (closer to the equilibrium potential for potassium, VK), but during an action potential, Vmtransiently approaches +50 mV (closer to the equilibrium potential for sodium, VNa). The membrane potential then rapidly returns to the resting potential and even briefly goes beyond the resting potential to approach VKbefore finally returning to the resting value of about −70 mV. The entire process takes about 3-5 ms. This potential reversal of more than 100 mV is responsible for electrical signaling in the nervous system, and is the basis of information transmission in the nervous system. Take quiz...

    Gastrointestinal (GI) Physiology - Part 5

    Monday, August 31, 2015

    The function of the gastrointestinal tract (GI tract) is to process food. During this process, food is moved from the mouth to the anus. Feeding and drinking are voluntary activities, but are strongly influenced by signals from higher brain centers involved in the sensations of satiety and thirst. Once ingested, water and nutrients are extracted from food without any conscious control. Throughout the entire process, the ingested material is moved along the GI tract. Finally, the undigested and non-absorbed materials are released as feces from the anus (under voluntary control when socially appropriate!). Take quiz...

    The function of the gastrointestinal tract (GI tract) is to process food. During this process, food is moved from the mouth to the anus. Feeding and drinking are voluntary activities, but are strongly influenced by signals from higher brain centers involved in the sensations of satiety and thirst. Once ingested, water and nutrients are extracted from food without any conscious control. Throughout the entire process, the ingested material is moved along the GI tract. Finally, the undigested and non-absorbed materials are released as feces from the anus (under voluntary control when socially appropriate!). Take quiz...

    Endocrinology - Part 2

    Tuesday, August 25, 2015

    Endocrinology is defined as the study of how chemical messenger molecules, referred to as hormones, influence physiological processes. By definition, a hormone is a signaling molecule that is released into the bloodstream, where the hormone can then travel to distant target cells and tissues within the body. Along with the nervous system, the hormones of the endocrine system provide an important means by which information travels within the body. Test your basic knowledge of the endocrine system by taking this simple quiz. Take quiz...
