Explanation Hormones provide negative feedback mechanism, for example, insulin is secreted to lower down the glucose level to the normal range, when there is an increased amount in the blood, while glucagon is secreted when the blood glucose decreases. Irregular secretion of hormones results in various conditions such as hyposecretion of insulin results in diabetes. The below diagram represents the location of endocrine glands that are related to the following disorders: Glands associated with following disorders are: 1. Cretinism- It is also known as iodine deficiency syndrome. Hypothyroidism results cretinism in children and it is a thyroid gland related disease. 2. Diabetes mellitus- Diabetes is a condition when the blood glucose is too high and it may be due to irregular secretion of insulin hormone from the pancreatic cells...

Question

Chapter 17, Problem 16RQ

Summary Introduction

To review:

The location of the endocrine glands in the human body.

Introduction:

Endocrine glands release their chemical secretions that are also known as hormones directly into the blood and are ductless. Exocrine glands release their secretions through ducts and directly to the target sites. Hormones mostly regulate physiological processes such as blood glucose level is regulated by insulin and glucagon hormones.
