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).
