range. In this instance the brain and the nervous system help to get our internal environments back to its normal state. An example of this is when an individuals body is too hot and our body begins to sweat in order for us to cool down. Our internal receptors react to make sure that we can return to out normal level. These receptors are needed in the negative feedback loop to help send a message about environmental stimuli to our central nervous system‚ after this our bodies then send signals

Raynaud’s Disease Raynaud’s disease is a vasospastic condition generally characterized by spasm of the arterioles in an individual’s extremities; fingers‚ hands‚ feet and toes (Frazier: 490) (Merck: 1790). Additionally‚ the nose‚ tongue and even the earlobes can be affected (Merck: 1790) (Cooke: 293). If the condition is deemed primary‚ it is known as Raynaud’s disease‚ or primary Raynaud’s phenomenon‚ and is inherently idiopathic (Merck: 1790) (Cooke: 294). On the other hand‚ if the condition

Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? The time during the relaxation part of cardiac cycle. 4. By clicking the Multiple

Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their

Parasympathetic Dominants often use sleep to overcome energy losses following periods of sustained alertness. The Autonomic Nervous System • The sympathetic branch of the autonomic nervous system is responsible for functions that require focus and decision making. It’s the branch that speeds up when you need to go fast. It goes into high gear when an emergency situation requires quick thinking and reflexes‚ spurts of energy‚ hyper vigilance‚ and rapid heart rate - a need to “fight or flee fast”
