Study Notes
Endocrine System Overview
- The endocrine system regulates metabolic activities through hormones, which have a lag time and prolonged effects.
- Major endocrine glands include the pituitary, thyroid, adrenal, pineal, thymus, hypothalamus, pancreas, and gonads.
- Hormones produce cellular changes by altering membrane permeability, stimulating protein synthesis, activating enzymes, inducing secretory activity, and stimulating mitosis.
- Hormones can act through second messengers involving regulatory G proteins or direct gene activation involving steroid hormones.
- Hormones are classified as amino acid-based or steroid-based, each with specific mechanisms of action.
- Hormone action on target cells depends on the blood hormone level, receptor count, and bond strength between hormone and receptor.
- Hormone release is controlled by humoral, neural, and hormonal stimuli, and hormones are removed from the blood by degrading enzymes, kidneys, liver, and the pituitary.
- The pituitary gland has a neurohypophysis and an adenohypophysis, which secrete hormones regulated by the hypothalamus.
- The adenohypophysis secretes growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, and prolactin.
- Growth hormone promotes protein synthesis and is regulated by growth hormone-releasing hormone and growth hormone-inhibiting hormone.
- Thyroid-stimulating hormone triggers normal thyroid development and secretory activity, while adrenocorticotropic hormone stimulates the adrenal cortex to release corticosteroids.
- Gonadotropins regulate the function of the ovaries and testes and are triggered by the hypothalamic gonadotropin-releasing hormone.
