type of hyperthyroidism that results when the immune system produces abnormal proteins that are similar in structure and function to TSH
a lack of thyroid hormones
hypothyroidism in infants; causes mental retardation, short stature, & abnormally formed skeletal structures
elevated rate of thyroid hormone secretion, causes an increased metabolic rate, extreme nervousness, and chronic fatigue

tissue on which a hormone acts
chemical messengers, secreted by endocrine glands into blood that acts on a target tissue to produce a specific response
gland that secretes to a surface or outward through a duct
gland that secretes (hormones, etc) internally
Major systems that regulate homeostasis
