Hormone and Glucose Regulation - Part I

These flashcards cover key concepts from the lecture on Hormone and Glucose Regulation, focusing on the endocrine system and hormones involved.

Endocrine System

A system responsible for hormonal regulation and homeostasis in the body.

Positive Feedback

A mechanism that causes a rise in hormone levels until there is a mechanism to stop their release.

Negative Feedback

A system that inhibits hormone synthesis and secretion to maintain homeostasis.

Thyroid Hormones

Includes thyroxine (T4) and triiodothyronine (T3), important for metabolism.

Parathyroid Hormone (PTH)

Regulates serum calcium levels and stimulates renal conversion of vitamin D.

Hypothalamus

A brain structure that influences pituitary gland function and coordinates the endocrine and ANS.

Islets of Langerhans

Clusters of endocrine cells in the pancreas that secrete hormones like insulin.

Pituitary Gland

Often referred to as the 'master gland', it regulates various hormonal functions.

Diabetes Mellitus

A metabolic disorder characterized by high blood sugar levels over a prolonged period.

Clinical Manifestations
