CENTRAL NERVOUS SYSTEM STIMULANTS CENTRAL NERVOUS SYSTEM STIMULANTS Definition Stimulants are a substance which tends to increase behavioral activity when administered. Primary action of a diverse group of pharmacologic agents – adverse effect associated with many drugs. Signs and symptoms * Elevate Mood * Increase Motor Activity * Increase Alertness * Decrease need for Sleep *In case of overdose lead to convulsion and death. Mode of Action * Block neurotransmitters

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

wonder why the body shivers when it gets cold? Homeostasis keeps body conditions steady and constant. So‚ this means that when the body shivers‚ that is homeostasis taking place trying to keep your body temperature at a constant degree. Homeostasis maintains normality in the body in many different ways. Some examples include osmoregulation‚ thermoregulation‚ chemical regulation‚ and behavioral homeostasis. While homeostasis controls these processes‚ homeostasis must also go through a separate process of

Cogdell 1 Torrey Cogdell July 30‚ 2013 Period 5‚ Lisa Harris Homeostasis Lab Report Objective: This experiment was conducted to determine how homeostasis maintains the bodies balance after doing a workout. Homeostasis is the maintaining of a balanced condition in the body despite changing external conditions or demands on the body. In this lab the participant was to execute an exercise to determine if homeostasis would maintain an stable heart beat and breathing rate. Materials: There

Homeostasis Imbalances: Diabetes Jessica Garcia Human Anatomy & Physiology I Professor Garcia March 24th‚ 2014 Homeostasis Imbalances: Diabetes Homeostasis is regulation of every system and organ in the body. How does diabetes affect homeostasis? In homeostasis‚ if the blood glucose level begins to decline‚ the pancreas releases the hormone glucagon‚ which then stimulates cells to release glucose into the blood stream. Now when the

Central Nervous System Stimulants Types Stimulants can range from mild legal forms like caffeine to severe illegal drugs like methamphetamines. Each type has different effects at different levels and all can be lethal if taken in excessive quantities. The first type is the cocaine family which consists of cocaine HCL‚ cocaine freebase or crack‚ and cocaine paste. Then there are a wide arrange of amphetamines which are synthetic versions of the ephedra plant like Adderall which is used to help with

released.[34] Homeostasis is the ability of an open system to regulate its internal environment to maintain stable conditions by means of multiple dynamic equilibrium adjustments controlled by interrelated regulation mechanisms. All living organisms‚ whether unicellular or multicellular‚ exhibit homeostasis.[35] To maintain dynamic equilibrium and effectively carry out certain functions‚ a system must detect and respond to perturbations. After the detection of a perturbation‚ a biological system normally

Exercise on Homeostasis Hypothesis: If a human being walks up and down a set of stairs for eight minutes with a set rest every two minutes‚ the body will present such changes as heart and breathing rates‚ perspiration level‚ body color and temperature because of the response of the body to change whilst exercising. Discussion Questions 1. What are the changes you observed in body color and perspiration level in response to? How do these changes contribute to the maintenance of homeostasis? The
