Endogenous pacemakers and exogenous zeitgebers are used to control biological rhythms. Biological rhythms are controlled by environmental factors such as light‚ temperature and food availability; these are known as exogenous (external) zeitgebers. However biological organisms are complex systems‚ where many different processes are taking place. This means that it would be useful to have something which would co-ordinate these processes‚ keeping everything in time – an endogenous pacemaker. This

Winter essay Now Embracing Winter Warmly Winter is a weather reality for most of us who live in North America. While the extremes and severity of said weather vary‚ depending on the latitudinal coordinate where you reside‚ it amazes me how much more people complain these days about the cold‚ snow and even road conditions. Maybe this form of amnesia about the verisimilitude of winter’s ways is tied to our hubris‚ born from the post-modern belief that technology trumps everything else‚ including

Alexis Carino 7/31/10 Paragraph Reviews Chapter One: Every Trip is a Quest (Except When It’s Not) In the opening chapter of Thomas C. Foster’s book‚ he explains the importance of a Quest.

example‚ it allows for energy conservation; it provides a period of time where there is no activity‚ thus allowing the conservation of energy which is essential for animals with high metabolic rates. Webb suggested that everyday sleep is similar to hibernation - sleep conserves energy at times when it’s harder to get resources (i.e at night time). Meddis suggested that sleep helps keep animals safe. By being quiet and still‚ they’re less likely to attract predators. However‚ sleep also makes animals vulnerable

Neurotransmitters Dr. C. George Boeree Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons‚ where they stimulate the muscle fibers. And they and their close relatives are produced by some glands such as the pituitary and the adrenal glands. In this chapter‚ we will review some of the most significant neurotransmitters. Acetylcholine Acetylcholine was the first neurotransmitter

The change in overall daylight potentially awaken these creatures from hibernation. Schools of feisty panfish will be there to gobble the feast. Panfish might remain in this deep silt area for a long time if frigid cold weather persists‚ or retreat to such a spot if a sudden cold snap arrives later
