Chapter 45 Hormones and the Endocrine System PowerPoint Lectures for Biology‚ Seventh Edition Lectures by Ching-wei Luo Hormone (from the Greek horman‚ to excite) • Overview: The Body’s Long-Distance Regulators • Hormone definition: a chemical signal secreted into the circulatory system and communicates regulatory messages within the body • Hormones may reach all parts of the body But only certain types of cells (target cells) are equipped to respond Q Two systems act individually

A woman training for a marathon just completed running 5 miles out of the 10 miles she will run for her training sessions today‚ some neurotransmitters that might be involved in this act would be epinephrine‚ dopamine‚ and endorphins. Epinephrine it deals with energy‚ and dopamine because it plays a key role in regulating pain & pleasure‚ which exercising is a mixture of both. Lastly‚ endorphins because when you

Unit 1 Case Study Addison’s disease is from a result from damage to the adrenal cortex. These two adrenal glands are located on top of the kidneys‚ where they are enclosed in a fibrous capsule and a cushion of fat. . The have an outer portion‚ called the cortex‚ which is a glandular tissue derived from embryonic mesoderm. The inner portion called the medulla‚ which is more like a knot of nervous tissue than a gland and it is part of the sympathetic nervous system. The adrenal

Human Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches

This interference ends up lowering the stress response initiated by the stress hormones. Beta blockers are structurally and functionally competitive antagonists that block the binding of catecholamines‚ epinephrine and norepinephrine with adrenergic beta receptors present on the sympathetic nervous system by blocking to the receptors themselves. These receptors mediate fear and flight-or-fight response. Beta blockers help combat heart failure by reducing the heart

Unit 2: The Psychology of Fitness Assignment 1: The Body’s Response to Acute Exercise Introduction: As a health and fitness instructor I need to be able to apply my anatomical and physiological knowledge to practical activities and exercises. I have conducted practical assessments to explore how the body responds to physical activity and exercise. I have then written a report‚ including all the anatomical and physiological changes that occur within each of the bodily systems. Acute exercises
