This document discusses abnormalities of the anterior pituitary gland and its hormones. It describes hypopituitarism, which is a deficiency in growth hormone secretion, as well as conditions like gigantism caused by excess growth hormone and acromegaly, characterized by coarse facial features. The clinical features of pituitary dwarfism are also mentioned. Photographs show the physical effects of these hormonal imbalances, such as disproportionate tall stature in gigantism or thickened skin and fingers in acromegaly.
