When the stimulus is delivered‚ the ermeability of the membrane at that point is changed; and c ‚ initiating the depolarization of the membrane. Almost as soon as the depolarization wave has begun‚ a repolarization wave follows it across the membrane. This occurs as b . Repolarization restores the h of the resting cell membrane

How well do the concepts of drive and homeostasis contribute to understanding sexual motivation? Both sexual motivation‚ hunger and thirst are biological motivations‚ a desire that directs behaviour (Myers‚ 2004‚ p. 420). However unlike sexual motivation which drives us to pleasure and procreation‚ hunger and thirst are needed to survive. In regards to the motivation behind hunger‚ drive reduction theory suggests that the bodys motivation to maintain homeostasis drives us to reduce our need for hunger

1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”

Homeostasis and Pain Management in Patient with Multisystem Failure Homeostasis and Pain Management in Patient with Multisystem Failure A. Assessment of Patient The assessment of Mrs. Baker should include vital signs including pulse oximetry. Given her difficulty in breathing‚ lung sounds should be auscultated. Because she is on two different medications that could affect blood pressure‚ lisinopril and hydrochlorothiazide (HCTZ)‚ hypotension could be one cause of her collapsing. In addition

Homeostasis is important in maintaining a healthy functioning of the body. Enzymes within the body are vitally responsible for speeding up chemical reactions and are often referred to as catalysts. In order to work at their optimum‚ enzymes need a specific constant temperature within the internal environment of the body to function correctly and reduce denaturing. A healthy human body should have a body temperature of 37∙C‚ the optimum temperature for enzymes to function. Therefore‚ the temperature

In this lab‚ homeostasis will be studied upon the two eggs in corn syrup and distilled water‚ and in each sucrose solution with different amounts of molarity. Homeostasis is the maintenance of balance between an organism or cell and its environment. Without homeostasis‚ many important aspects of the body such as body temperature‚ blood sugar‚ heart rate‚ blood rate‚ and pH of blood would not be kept at the proper balance. This could eventually result in death due to improper amounts of certain substances

1) What is the role of calcium ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting
