Endocrine System Part 2 - Hormone Cascades

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
