All the following are examples of atrophy Except

All Answers Except for D are examples of atrophy. Atrophy of skeletal muscles can result from a loss of innervation due to the spinal cord or peripheral nerve trauma. Inactivity, as is often seen following the long-term immobilization of an extremity in a cast, has the same effect. Hypophysectomy is accompanied by atrophy of the thyroid, adrenal coex, and ovary, which are all organs that depend on stimulation by pituitary trophic hormones. The brain atrophies with advancing age. Estrogen exes trophic effects on the endometrium, causing hyperplasia rather than atrophy. Endometrial atrophy occurs following ovariectomy or after the menopause when the ovaries no longer produce estrogen.
