Study Notes
Endocrine Glands and Hormones
- Endocrine glands: Pituitary gland, Thyroid gland, Parathyroid glands, Pancreas, Adrenal glands, Sex glands
- Functions of endocrine glands: regulate growth and development, maintain homeostasis, respond to stress
Pituitary Gland
- Anterior Pituitary: produces 6 hormones, regulates growth and development, stimulates other endocrine glands
- Posterior Pituitary: produces 2 hormones, regulates water balance and uterine contraction
- Hormones produced by Anterior Pituitary:
- Growth Hormone Releasing Hormone (GHRH)
- Thyroid-Releasing Hormone (TRH)
- Corticotropin Releasing Hormone (CRH)
- Gonadotropin Releasing Hormone (GnRH)
- Prolactin Releasing Hormone (PRH)
- Growth Hormone (GH)
- Thyroid-Stimulating Hormone (TSH)
- Adrenocorticotropic Hormone (ACTH)
- Follicle-Stimulating Hormone (FSH)
- Hormones produced by Posterior Pituitary:
- Antidiuretic Hormone (ADH)
- Oxytocin (OT)
Thyroid Gland
- Produces 2 hormones:
- Thyroxine (T4)
- Triiodothyronine (T3)
- Calcitonin
Parathyroid Gland
- Produces 1 hormone:
- Parathormone (PTH)
Pancreas
- Produces 4 hormones:
- Insulin
- Glucagon
- Somatostatin
- Pancreatic Polypeptide
Adrenal Glands
- Adrenal Cortex:
- Produces 3 types of hormones:
- Mineralocorticoids (Aldosterone)
- Glucocorticoids (Cortisol, Corticosterone)
- Sex Hormones (Androgens, Estrogen, Progesterone)
- Produces 3 types of hormones:
- Adrenal Medulla:
- Produces 3 hormones:
- Catecholamines (Adrenaline/Noradrenaline, Dopamine)
- Produces 3 hormones:
Pathophysiology
- Hyposecretion: underproduction of hormones
- Hypersecretion: overproduction of hormones
- Disorders of Pituitary Gland:
- Panhypopituitarism: underproduction of all Anterior Pituitary hormones
- Gigantism: oversecretion of Growth Hormone during childhood
- Pituitary Dwarfism: underproduction of Growth Hormone during childhood
- Acromegaly: oversecretion of Growth Hormone after adolescence
- Disorders of Pancreas:
- Diabetes Mellitus: impaired carbohydrate, fat, and protein metabolism
- Type I Diabetes (IDDM): lack of insulin secretion
- Type II Diabetes (NIDDM): decreased sensitivity of target tissues to insulin
- Disorders of Adrenal Cortex:
- Cushing's disease: hypersecretion of cortisol, leading to high blood glucose levels and lipid deposits
- Addison's disease: hyposecretion of cortisol, leading to low blood glucose levels and low Na levels
