Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

NAME LAB TIME/DATE _ Endocrine System Physiology: Computer Simulation Metabolism The following questions refer to Activity 1: Determining Baseline Metabolic Rates. 1. Which rat had the fastest baseline metabolic rate? -------------------------The normal rat 2. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. The thyroidectomized rat had a lower baseline metabolic rate beause the removal of its thyroid gland prevented it

the endocrine glands. The endocrine system sends messages to the endocrine glands in your body that include the adrenal‚ pituitary‚ thyroid‚ and parathyroid glands‚ as well as‚ the hypothalamus‚ pancreas‚ ovaries‚ and testes. There are two main systems in the body that control the proper functioning of the body. The nervous system sends ultra fast electrical alerts and messages from the brain. It is divided up into two main systems‚ the central nervous system and peripheral nervous system. The

RESEARCH 1. Give the importance of the endocrine system ~ The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones‚ chemical messengers. The major areas of control and integration include responses to stress and injury‚ growth and development‚ absorption of nutrients‚ energy metabolism‚ water and electrolyte balance‚ reproduction‚ birth‚ and lactation. The endocrine system is composed of glands that release their hormones directly

LAB #2 QUESTIONS PART A: ENDOCRINE GLANDS OF THE HUMAN 1. Complete the following chart: Please see the attached chart for the Endocrine System. 2. Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

Chapter 45 Hormones and the Endocrine System Lecture Outline Overview: The Body’s Long-Distance Regulators An animal hormone is a chemical signal that is secreted into the circulatory system that communicates regulatory messages within the body. A hormone may reach all parts of the body‚ but only specific target cells respond to specific hormones. A given hormone traveling in the bloodstream elicits specific responses from its target cells‚ while other cell types ignore that particular

December 12‚ 2014 Nancy Ault Hormones and Behaviors The endocrine system plays a big part in the production and distribution of hormones into the body. These hormones can affect an individual’s behavior greatly. Hormones such as estrogen affect a woman’s moods and emotions; steroid hormones cross the bloodstream directly to the brain and affect the neurons directly. This action can cause changes in behavior for both men and women. The endocrine system acts as a communication device within the human body

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 released into your bloodstream.
