The thyroid gland is the main gland of the ______ system.
Endocrine
The thyroid gland is small, butterfly-shaped, and found in the ____ of the neck.
Front
The thyroid gland responds to the thyroid-stimulating hormone (TSH) secreted by the ______ gland to secrete thyroid hormones.
Pituitary
The thyroid regulates:
Fat and CHO regulation
Body temperature
Respiration
Cholesterol levels
Heart rate
Brain development
Blood Ca levels
Skin, hair growth
Digestion
The main thyroid hormones include: (3)
Thyroxine (T4)
Triiodothyronine (T3)
Calcitonin
Thyroid hormone synthesis requires: (2)
Tyrosine and Iodine
Initially, TPO produces a majority of the T4 hormone. However, most T4 is converted to T3 in the _____ , kidneys, and GI tract. T3 is the predominant and active form in the body.
Liver
Hypothyroidism can be caused by an autoimmune disease called _______ _________ , ______ deficiency or due to issues converting T4 to T3.
Hashimoto’s thyroiditis, Iodine
Hashimoto’s thyroiditis produces antibodies that attack _____, the enzyme required to make T4 and T3.
TPO - Thyroid peroxidase enzyme
There is a strong association between Hashimoto’s thyroiditis and _____ disease.
Celiacs
Factors that may trigger the onset of Hashimotos Thyroiditis include _________ dysfunction, oxidative stress, aging, menopause, and pregnancy.
Adrenal
Factors that decrease the conversion of T4 to T3 include selenium or zinc deficiency, high cortisol, heavy metals, and ____ or _____ dysfunctions.
Liver, kidney
_______ and _____ are cofactors for the enzyme (Deiodinase) needed to convert T4 to T3.
Selenium, Zinc
The most common cause of hyperthyrpoidsim is the autoimmune disease called ______ disease.
Graves
In Graves disease, the antibodies bind with the _____ receptors, which stimulates excessive T4 and T3 production.
TSH
Triggers for Graves disease is _____ and stress.
Genetics
A factor contributing to hyperthyroidism not related to Grave’s disease is _______ of T4 to T3.
Over conversion
Symptoms of hypothyroidism include: feeling _____, dry skin, hair loss, fatigue, weight gain, and constipation.
Cold
Symptoms of hyperthyroidism include: weight loss, bulging ____, anxiety, rapid heart rate, loss of bone density, and sleep disturbance.
Eyes
Increased ______ synthesis causes bulging eyes in hyperthyroidism.
Protein
A symptom of both hypothyroidism and hyperthyroidism is _______. In hypothyroidism, it is a result of increased TSH, and in hypothyroidism, it is a result of overstimulated thyroid.
Goiter (Enlarged thyroid)
The most common lab ordered for thyroid disorders is ____.
TSH
The optimal range for TSH is 0.2- ___ mIU/L
1.9
T/F: People can still be experiencing thyroid disorders even if their TSH lab values are in the reference range of 0.2-5.5 mIU/L.
True, which is why the optimal range of 0.2-1.9 mIU/L is used
