Growth Growth and development are the most fundamental characteristics of all living organisms. The physiological definition of growth is “An irreversible change in the organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral

(neurohypophysis). The anterior lobe secretes at least seven hormones. One hormone‚ the human growth hormone (HGH)‚ promotes body growth by accelerating protein synthesis. This hormone is also known as somatotropin. A deficiency of the hormone results in dwarfism; an over secretion results in gigantism. Another hormone of the anterior pituitary is prolactin‚ also called lactogenic hormone (LH). This hormone promotes breast development and milk secretion in females. A third hormone is thyroid-stimulating

Achondroplasia In humans achondroplasia is the most common form of non-lethal skeletal dysplasia (short limb dwarfism)‚ affecting over 250‚000 people worldwide. The incidence is approximately one in 10‚000-30‚000 live births. (1-7) Achondroplasia is characterised by short stature (average height of 120-132cm (2‚3)) with disproportionately shorter proximal limb bones‚ a long trunk with a narrow thorax‚ macrocephaly with frontal bossing and mid face hyperplasia. (1-4) People with achondroplasia also

Bovine Growth Hormones: Should We Use Them? Michelle Szalasny Dr. Juan Bouzat Sarah Wofford Biology 2040H Fall 2013 Introduction Recombinant Bovine Growth Hormone‚ also referred to as Bovine Somatotropin (rBST)‚ is a genetically engineered growth hormone most commonly manufactured by Monsanto. Monsanto sells this drug under the name of “Posilac” to dairy farmers who choose to use the growth hormone. Although most of these bovine growth hormones

Extreme emotional deprivation can interfere with a chemical production and cause chosocial dwarfism which appears at about age two – fifteen. Typically the child would be short and have an underdeveloped skeletal size. Childhood injuries often happen around these ages and are said to be caused by complete accidents or a child not being as attentive
