Study Notes
Thyroid Gland
- Endocrine gland located around the trachea in the neck
- Produces hormones crucial for regulating body temperature, skin moisture, and blood levels of oxygen, calcium, and cholesterol
Grave's Disease
- Autoimmune disorder leading to hyperthyroidism
- Associated symptoms include goiter (enlarged thyroid) and exophthalmos (protruding eyes)
Hyperthyroidism
- Condition characterized by excessive activity of the thyroid gland
- Results in an overproduction of thyroid hormones
HPT Axis
- Hormonal cascade known as the Hypothalamic-Pituitary-Thyroid (HPT) axis
- Responsible for maintaining homeostasis, such as regulating body temperature
TRH (Thyrotropin Releasing Hormone)
- Hormone secreted by the hypothalamus
- Plays a crucial role in the HPT axis by stimulating the release of TSH (Thyroid Stimulating Hormone)
Tropic Hormone
- Type of hormone that stimulates the secretion of another hormone
- Essential for coordinating hormone production among various glands
TSH (Thyroid Stimulating Hormone)
- Hormone released by the anterior pituitary gland
- Stimulates the thyroid gland to release thyroid hormones, crucial for metabolic processes
TRAb (Thyrotropin Receptor Antibodies)
- Abnormal antibodies that mimic TSH
- Lead to overproduction of thyroid hormones, contributing to hyperthyroidism conditions like Grave's disease
