a. thyroid.
b. pituitary gland.
c. pancreas.
d. myelin.
e. adrenal gland.

Answer 1

Mrs. Tamimi's short stature was most likely caused by a deficiency in growth hormone produced by the pituitary gland, leading to a condition known as pituitary dwarfism.

Step-by-step explanation:

The correct option is B:

Mrs. Tamimi's short stature was likely influenced by the lack of a growth hormone produced by the b. pituitary gland.

Human growth hormone (GH) is essential for normal growth and development throughout childhood. The pituitary gland, located at the base of the brain, produces GH, which stimulates the growth of bones and other tissues. In children, a deficiency in GH can lead to a condition known as pituitary dwarfism, where growth is significantly reduced, often resulting in an adult height under 4 feet.

On the other hand, overproduction of GH can cause gigantism or, if it occurs in adults, acromegaly, characterized by an abnormal enlargement of bones in the hands, feet, and face. GH levels naturally decline with age, but during childhood and adolescence, appropriate levels are crucial for achieving typical adult stature.
