Study Notes

Endocrine System Overview

The endocrine system comprises a network of glands releasing hormones into the bloodstream, regulating various bodily functions.
These glands are "ductless," unlike exocrine glands which secrete through ducts.
Hormones act on specific target tissues due to the presence of specific receptors on target cell membranes.
Hormones are potent, effective in minute quantities.
Hormones regulate growth, metabolism, reproduction, and behavior.

Endocrine Glands

Pineal gland
Hypothalamus
Pituitary gland (hypophysis)
Thyroid gland
Parathyroid glands
Adrenal glands
Pancreatic islets
Ovaries
Testes

Hormone Types

Steroid hormones: Derived from lipids, primarily produced by the sex glands (gonads) and adrenal cortex.
Amino acid hormones: Include proteins and protein-like compounds, produced by all endocrine glands except the gonads and adrenal cortex.

Examples of Hormones

Anterior pituitary: Growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL).
Posterior pituitary: Antidiuretic hormone (ADH), oxytocin.
Pancreatic islets: Insulin, glucagon.
Ovary: Estrogen, progesterone.

Terminology

Endocrine: Pertaining to a ductless gland, secreting hormones into the blood.
Hormone: A secretion of an endocrine gland, with regulatory effects on tissues and organs.
Pancreatic islet: Clusters of endocrine cells in the pancreas, regulating glucose metabolism.
Thyroid gland: Endocrine gland affecting metabolism and growth, located near the larynx.
Target tissue: The specific tissue on which a hormone acts.
Receptor: A site on a cell membrane or within a cell, where a hormone can attach and exert its effect.
Steroid hormone: A lipid-derived hormone, including sex hormones and adrenal cortex hormones.
Prostaglandins: A group of hormones found throughout the body with various effects (e.g., uterine contractions, blood pressure regulation).
