The Pituitary Gland And Dwarfism

The Pituitary Gland and Dwarfism


The Pituitary Gland is situated at the base of the brain and it produces
hormones which control growth. Too large an amount of these hormones causes
giantism, a condition where facial features, hands, etc. become abnormally large.
Too little causes dwarfism, where the overall stature of a person is very small.
Dwarfism is the condition of being undersized, or less than 127 cm (50
in) in height. Some dwarfs have been less than 64 cm (24 in) in height when
fully grown. The word midget is usually applied to dwarfs. Another growth
disorder disease is Cretinism which is a result of a disease of the thyroid
gland it is the cause of most dwarfism in Europe, Canada, and the United States.
Other causes of dwarfism are Down's syndrome, a congenital condition with
symptoms similar to those of cretinism, achondroplasia, a disease characterized
by short extremities resulting from absorption of cartilaginous tissue during
the fetal stage, spinal tuberculosis, and deficiency of the secretions of the
pituitary gland or of the ovary.
Causes of pituitary dwarfism may vary. Abnormally short height in
childhood may be due to the pituitary gland not functioning correctly, resulting
in underproduction of growth hormone. This may result from a tumor in the
pituitary gland, absence of the pituitary gland, or trauma.

  • Metabolic Muscular and Nervous Systems
    Metabolic Muscular and Nervous Systems The immediate source of energy for muscular contraction is the high-energy phosphate compound called adenosine triphosphate (ATP). Although ATP is not the only energy-carrying molecule in the cell, it is the most important one, and without sufficient amounts of ATP most cells die quickly. The three main parts of an ATP molecule are: an adenine portion, a ribose portion, and three phosphates linked together. The formation of ATP occurs by combining adenosine
