PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability

In most populations‚ the median age of its detection tends to be quite low‚ actually below 40 in most cases. It is currently the fastest growing cancers among women. Despite the fact that

One such time is during puberty. This is the time in an individual’s life that the body changes. Hormones activate behaviors such as aggressiveness and sleepiness (Morris‚Maisto‚ 2005). Mood‚ emotional reactivity‚ learning‚ and resistance to diseases are also attributed to hormones. The thyroid gland produces

Hormones Every living organism on Earth has some sort of organ system. For example‚ humans have their endocrine system. The endocrine system is a group of organs that release different biological substances called hormones. There are vast amounts of hormones‚ which means there are multiple uses that are necessary for survival. Hormones have multiple roles in the human body. For example‚ they assure that growth‚ development and maturation occurs properly and on time. Also hormones‚ help control

Heredity and Hormones Human behavior is influenced by heredity and hormones. There are many parts to this‚ such as the endocrine system‚ glands that secrete hormones‚ genetics‚ behavior genetics‚ and evolutionary psychology. The following is a closer look at the endocrine system and hormones. The endocrine system works in conjunction with the nervous system using what is termed “chemical conversation.” The endocrine glands release substances referred to as hormones that are

111 Iodine Description: Is a trace mineral that your body uses in small amounts to synthesize thyroid hormones that are necessary for regulating the body growth‚ development‚ metabolism and body temperature. Most of the iodine in the body is found in the thyroid gland‚ but is found also in the blood and muscles. The body contains approximately 20 to 30 mg of iodine which is mostly stored in the thyroid gland located in front of the neck. Food sources: Milk is the major source‚ fish from the sea

Metabolism is the set of chemical reactions that happen in the cells of living organisms to sustain life. These processes allow organisms to grow and reproduce‚ maintain their structures‚ and respond to their environments. I never thought that people blame their weight on slow metabolism‚ but this article have changed my opinion on why someone can blame on metabolism I learned that metabolism is linked to weight. Metabolism is the process by which your body changes what you eat and drink into energy

Heredity and Hormones The Influences of heredity and hormones on human behavior The Influence of Heredity and Hormones on Human Behavior Human behavior has always been fascinating to many people. Scientists have long studied the factors that cause and contribute too many different types of human behaviors. The Effects Heredity Has On Human Behavior Many different traits are passed along to people through genetics. Some of these traits include the basics such as eye color‚ height‚ and

I will identify the hormones and glands as well as describe the endocrine system. Heredity‚ and hormones‚ can affect behavior. Human behavior starts as thought processes in the brain. The different roles are that hormones can change our behaviors if they become imbalanced. Hormones are secreted by glands‚ which are controlled by a part of the brain called the hypothalamus
