The Limbic System Most reptiles and lower order organisms only have the “old brain”‚ the evolutionarily oldest part of the brain responsible for vital tasks such as breathing and sleeping‚ whereas higher order organisms have a limbic system. The old brain is comprised of the pons‚ the medulla oblongata‚ the brain stem‚ the thalamus‚ the cerebellum‚ and the reticular formation. The reticular formation is a network inside of the brain stem‚ part of the “old brain” that is essential for arousal (sleeping

ANATOMY AND PHYSIOLOGY OF THE DIGESTIVE SYSTEM The digestive system is basically a tube running through the body from the mouth to the anus. The organs of the digestive system include the oral cavity (mouth)‚ esophagus‚ stomach‚ small and large intestine and rectum. Their role is to break down food and deliver the products to the blood for dispersal to the body cells. The undigested food that remains in the tract leaves the body through the anus as feces. The break down activities that

A system is a group of organs that work together and provide an organism with an advantage for survival. It is the most complex organization in your body and the final level of the progression from cells to tissues to organs and then systems. Systems work alone and with other systems to allow your body to maintain homeostasis. Homeostasis is a stable internal environment that allows you (and your cells) to survive. While every one of your systems is needed to survive‚ your nervous system is the

10 Soft Systems and Hard Contradictions* Lars Mathiassen Peter A. Nielsen Abstract. Checkland ’s Soft Systems Methodology for defining and solving problems in organizations is presented on the basis of an application of the methodology. In many ways this approach represents an improvement in relation to more traditional approaches to computer-based information systems. Based on an experiment we explore the possibilities of combining the practical usefulness of soft systems thinking with the

What does the term “feedback system” refer to with respect to homeostasis? A cycle of events in which a variable‚ such as body temperature‚ is continually monitored‚ assessed‚ and adjusted. 4. List the three components of a feedback system and describe each briefly. A sensor that detects a change in

The glands that secrete hormones are part of the endocrine system (pituitary‚ thyroid‚ adrenals and pancreas‚ to name a few) and work in large part to keep the body’s natural balance in check.
