abnormal largeness or excessive growth due to hormonal imbalance. Example The most remarkable example of a person with gigantism was Robert Wadlow (tallest man in history)‚ called the Alton giant‚ who stood 8 feet 11 inches tall at the time of his death in his mid-20s. He showed no indication of an end to his growth even at the time of his death. Causes Gigantism is abnormally large growth due to an excess of growth hormone during childhood‚ before the bone growth plates have closed. The most common

Endocrine system The Endocrine system is very important to our body. This system regulates our mood‚ growth‚ metabolism‚ tissue development‚ sexual functions and reproductive process. It is a very complex system with many different hormones and glands. I am going to write about the pituitary gland and thyroid. The pituitary gland is very often considered to be the most important glad in the Endocrine system. The Thyroid produces thyroxine andtriiodothyronine. The Pituitary gland is no bigger

The communication and control function of the Endocrine System are key parts in order for the body to maintain homeostasis. The Endocrine and Nervous system unify to make the body work as a unit because they communicate and control. 3. Most hormones are controlled by negative feedback. Explain how

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

Lasley in the article Growth Hormone Level in the Blood of Dwarf and Normal Hereford Cattle. After all the testing they did Marlow‚ Rooney and Mestanza (1962)‚ for example‚ found that the anterior pituitary glands of snorter dwarf cattle possessed growth hormone but in amounts significantly lower than found in the pituitaries of normal cattle. There are many ways to test for snorter dwarfism

of which secretes a type of hormone into the bloodstream to regulate the body. It derives from the Greek words endo meaning inside‚ within‚ and crinis for secrete. The endocrine system is an information signal system like the nervous system. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream that attach to target tissue and allow communication among cells. Hormones regulate many functions of an organism‚ including mood‚ growth and development‚ tissue function
