Endocrine Maintains homeostasis. Ex. Growth rate‚ body temp‚ hunger feelings. Hormone Chemical messenger‚ that secretes into blood by an endocrine gland. Gland Secretes chemical substances used by the body Exocrine gland Secretes chemical substances into a duct Endocrine gland Ductless glands that secrete hormones Target cell Cell on which the hormone exerts an effect Affects of hormones Activation or inactivation of enzymes‚ stimulates mitosis‚ plasma membrane permeability change‚ synthesis

The causes and effects of diabetes Type 1 diabetes causes Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally. This is called an autoimmune reaction‚ or autoimmune cause‚ because the body is attacking itself. There is no specific diabetes causes‚ but the following triggers may be involved: • Viral or bacterial infection • Chemical toxins within food • Unidentified

Hunger is the physiological need for food. Numerous physiological cues tell us we are hungry‚ such as an empty or growling stomach‚ a decrease in blood glucose levels‚ and alterations in circulating hormones (e.g.‚ increased glucagon and ghrelin and decreased insulin). Appetite is the psychological desire to eat‚ and is associated with sensory experiences or aspects of food such as the sight and smell of food‚ emotional cues‚ social situations‚ and cultural conventions. Hunger acts as the more

Mellitus Type 2 Diabetes Mellitus (DM)is a metabolic disease mostly seen in adulthood due to insulin resistance‚ genetic factor‚ and environmental influences such as obesity. In addition‚ children have become victim of type 2 DM due to poor dietary intake. Furthermore‚ the hepatic glucose production increases‚ altered insulin production and reduced glucose absorption results in hyperglycemia. The insulin imprints become resistant to hormonal impulses due to increased blood glucose levels leading

* Difference in Somatic and Autonomic Nervous System * The somatic nervous system consists of nerves that provide VOLUNTARY control over skeletal muscles * The autonomic nervous system exerts INVOLUNTARY control over the contraction of smooth muscle‚ cardiac muscle‚ and glandular activity. * Basic function of the Sympathetic VS Parasympathetic Systems * Sympathetic system= “fight of flight” * Parasympathetic system= “rest and digest” * Both autonomic branches are required

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

There are two types of DM; insulin dependent DM (IDDM or type 1) and non-insulin dependent DM (NIDDM or type 2) Type 1 is caused by the destruction of pancreatic b cell destruction‚ which can be predicted by the detection of the presence of antibodies (Abs) to islet cells‚ (Pitteloud‚ Philippe (2000)) insulin and glutamic acid dehydrogenase (GAD) (a neurotransmitter) and a decrease in b cell insulin secretion. This destruction causes a decrease in insulin production‚ the hormone which stimulates

Type 2 Diabetes is a group of metabolic diseases in which a person has high blood sugar‚ either because the body does not produce enough insulin‚ or because cells do not respond to the insulin that is produced. It is caused by very low insulin levels in one’s body‚ resistance to insulin‚ no insulin production or a combination of factors. Insulin is a hormone which is normally produced by the pancreas that works in the body to control blood sugar levels in one’s body by moving sugars out of
