Question: Describe five different organelles and their functions. Explain the similarity and differences between eukaryotic cells and prokaryotic. All eukaryotic cells‚ whether from animals‚ plants‚ protists‚ and fungi‚ are fundamentally similar to one another but different from prokaryotic cell. A eukaryotic cell contains various other organelles‚ which perform specific functions in the cell. These organelles can be organized into few basic functional groups such as genetic control‚ distribution

It may stimulate testerone production in males. Influences the growth and activity of the thyroid gland
Premium Hypothalamus Endocrine system Hormone
HORMONES Hormones are a class of regulatory biochemicals produced in all multicellular organisms by glands‚ and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. They serve as a major form of communication between different organs and tissues. Hormones regulate a variety of physiological and behavioral activities‚ including digestion‚ metabolism‚ respiration‚ tissue function‚ sensory perception‚ sleep‚excretion‚ lactation‚ stress‚ growth and

2010 Abstract Diabetes is a disease that affects currently 23.6 million people‚ about 7.8% of the population. Diabetes comes from a high level of sugar in the blood for a long period of time. Ways to control it are by diet‚ exercise‚ medicine and insulin injections. There are four known types of diabetes: Prediabetes‚ which is a condition that raises the risk of developing type 2 diabetes; Type 1‚ which generally affects primarily the younger population; Type 2‚ which generally affects the adult population;

send a message to the hypothalamus which sends a message to the pancreas‚ which is the major organ of the endocrine system‚ so it secretes the hormone glucagon that stimulate the cells to release glucose which control the high levels of sugar in blood. On others hands‚ when the levers of sugar in blood begin to increase the pancreas releases insulin which stimulate cells to eliminate glucose from the blood. These two responses of the organism to internal changes are part of negative feedback system

Anatomy and Physiology P5/M2 - Homeostasis Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant. In humans homeostasis happens when the body regulates its body temperature in

Diabetes mellitus is a group of metabolic diseases in which the individual has high blood glucose levels as a result of the inability of the pancreas to produce insulin‚ or as a result of the cells in the body not responding to the insulin produced. The aim of this documentation is to outline the normal regulation of blood glucose levels in the body which includes the role of the hormone producing alpha cells and beta cells in regulating these levels‚ and the effect that the pathophysiology of diabetes

Homeostasis‚ also spelled homoeostasis (from Greek: ὅμοιος‚ "hómoios"‚ "similar")‚ is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH). It is a process that maintains the stability of the human body’s internal environment in response to changes in external conditions. The concept was described by Claude Bernard

increased levels of other hormones. This affects how the body makes insulin during pregnancy; these hormones also increase blood glucose levels which causes gestational diabetes. Many patients of this type of diabetes can control and prevent it with proper exercise and diet. However‚ some of them would need to take medication that controls blood glucose. Type 1 Diabetes: This type of diabetes occurs when the body fails to produce insulin. This is usually genetic and can be found in much younger people
