Gigantism
and acromegaly are the two diseases resulting from hyper function of the
pituitary gland.
Gigantism
and acromegaly are conditions that are nearly always due to a pituitary adenoma
that is because of excessive secretion of a growth hormone called hypersomatotropism.
<span>If GH
hypersecretion begins in childhood, before closure of the epiphyses pituitary
gigantism occurs. It is a rare condition where skeletal growth velocity and
ultimate stature are increased, but little bony deformity occurs. However,
soft-tissue swelling occurs, and the peripheral nerves are enlarged. Hypogonadotropic
hypogonadism and deferred puberty is also normally present, resulting in a
eunuchoid habitus. While Acromegaly
occurs after the growth plate cartilage fuses in adulthood, it is the same
disorder of IGF-I excess but in acromegaly, an unadorned disease that morbidity
and mortality rates are high because its often diagnosed late, where the
disease is associated with cardiovascular, cerebrovascular, and respiratory
disorders and malignancies. </span>
Answer: The cell is the structural and functional unit of all living organisms, and is sometimes called <u>the "building block of life."</u> Some organisms, such as bacteria, are unicellular, consisting of a single cell.
Answer:
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
