A lobectomy of the thyroid gland A total thyroidectomy. Hemithyroidectomy — Entire isthmus is removed along with 1 lobe. Done in benign diseases of only 1 lobe. Subtotal thyroidectomy — Removal of majority of both lobes leaving behind 4-5 grams (equivalent to the size of a normal thyroid gland) of thyroid tissue on one or both sides—this used to be the most common operation for ...
Compensatory growth is a type of regenerative growth that can take place in a number of human organs after the organs are either damaged, removed, or cease to function. [1] Additionally, increased functional demand can also stimulate this growth in tissues and organs. [ 2 ]
Skin tissue can be regenerated in vivo or in vitro. Other organs and body parts that have been procured to regenerate include: penis, fats, vagina, brain tissue, thymus, and a scaled down human heart. One goal of scientists is to induce full regeneration in more human organs. There are various techniques that can induce regeneration.
Two types of regeneration in human adults are currently recognised; spontaneous and induced. [2] Spontaneous regeneration occurs in the human body naturally. The most recognised example of this is the regeneration of the liver, [16] which can regenerate up to two thirds of its mass when injured by surgical removal, ischaemia or after exposure ...
“When the thyroid underperforms, people often feel tired, gain weight, get cold easily, or even feel depressed. These symptoms can make life tough, so doctors often prescribe levothyroxine to ...
A nodule or lobe of the thyroid is sometimes removed for biopsy or because of the presence of an autonomously functioning adenoma causing hyperthyroidism. A large majority of the thyroid may be removed (subtotal thyroidectomy) to treat the hyperthyroidism of Graves' disease, or to remove a goiter that is unsightly or impinges on vital structures.
[2] [3] [4] Regeneration can either be complete [5] where the new tissue is the same as the lost tissue, [5] or incomplete [6] after which the necrotic tissue becomes fibrotic. [ 6 ] At its most elementary level, regeneration is mediated by the molecular processes of gene regulation and involves the cellular processes of cell proliferation ...
The existing epithelial cells can replicate, and, using the basement membrane as a guide, eventually bring the kidney back to normal. After regeneration is complete, the damage is undetectable, even microscopically. [citation needed] Healing must happen by repair in the case of injury to cells that are unable to regenerate (e.g. neurons).
