Parathyroid & Thyroid Glands

Parathyroid & Thyroid GlandsHannah Chung & Alina KimHAP 5Function & Importance of Endocrine SystemFunction: Regulate the body through hormones.

Importance: Respond to signals from the brain and to changes in chemicals in the blood.

Parathyroid Gland

Measures about 6 mm in length and 3-4 mm in width3Thyroid Gland

Normally about the size of two thumbs held together in the shape of VLocationThyroid: side of the trachea; spreads across front of throat; shaped like a butterflyParathyroid: located on back lobes of thyroid

Thyroid Gland regulates bodys metabolismParathyroid regulates the calcium level within the blood and the bones.Thyroid gland produce T3 and T4 hormones which stimulates body tissues to produce proteins and increase the amount of O2.

Role & Function

3 HormonesCalcitoninParathyroid hormone (parathyroid)Thyroxine

7Calcitonin

Function: regulates balance of Calcium (Ca) and Phosphorus (P) in bones and blood; increases amount of calcium bones can accept. 8Parathyroid Hormone/ Parathormone (pTH)Function: regulates level of calcium in bloodReleased in response to decreased calcium levels raises calcium levelsWorks with calcitonin

Animation: Parathyroid Hormone9Thyroxine (T4)Function: stimulates metabolism and oxygen consumptionReleased in response to TSH

Animation: Mechanism of Thyroxine Action10DiseasesHypothyroidism- when ones thyroid gland doesnt produce enough of certain major hormones. Causes: autoimmune disease, treatment for hyperthyroidism, and radiation therapy.Symptoms: Fatigue, increased sensitivity to cold, dry skin, puffy face, and elevated blood cholesterol.

http://www.ncbi.nlm.nih.govDiseasesHyperparathyroidism- an excess of parathyroid hormone in the blood stream from over activity of one or more of four parathyroid glands.Cause: unable to maintain proper levels of both Ca and P.Symptoms: fragile bones (osteoporosis), kidney stones, and loss of appetite.
