Question

What is the relationship between cretinism and thyroxine (T4)?

A. Cretinism is a condition of excess thyroxine (T4) production.
B. Cretinism is caused by the deficiency of thyroxine (T4) in the body.
C. Cretinism is unrelated to thyroxine (T4) levels.
D. Cretinism results from an overproduction of thyroxine (T4) and an underproduction of triiodothyronine (T3).

Answer 1

The relationship between cretinism and thyroxine (T4) is B. Cretinism is caused by the deficiency of thyroxine (T4) in the body.

Step-by-step explanation:

Cretinism is a condition that results from the deficiency of thyroxine (T4) in the body. Thyroxine is a crucial thyroid hormone responsible for regulating metabolism and promoting normal growth and development. When there is a lack of thyroxine during early development, it can lead to cretinism, a form of congenital hypothyroidism.

Individuals with cretinism may experience stunted physical and mental development, intellectual disabilities, and other health issues due to the insufficient levels of thyroxine. Thyroxine replacement therapy is often administered to manage the condition and support normal growth and development.

Option B is correct.
