How Would an Elevated Level of Thyroid Hormone in the Body

Question

How would an elevated level of thyroid hormone in the body affect skeletal muscles?
A) It would stimulate atrophy.
B) It would stimulate hypertrophy.
C) It would stimulate energy use and heat production.
D) It would decrease heat production by muscle tissue.
E) It would cause an increase in muscle mass.

Accepted Answer

An elevated level of thyroid hormone stimulates the metabolic rate in the body, which includes skeletal muscles. This results in an increased energy use and heat production by the muscles. This can lead to weight loss and a decrease in muscle mass in some cases due to the increased metabolic rate, but it can also potentially stimulate muscle growth (hypertrophy) depending on the individual's diet and exercise habits. Therefore, the best answer is C as it is a more generalized and accurate statement about the effects of elevated thyroid hormone levels on skeletal muscles.
