• Organ System

  Nervous, Endocrine, Reproductive
• Hormones travel through the bloodstream to target organs or tissues where they bind to specific receptors and trigger responses.
• The endocrine system is made up of glands that produce hormones, which are chemical messengers that regulate various bodily processes.
• The hypothalamus acts as the control center of the endocrine system by producing releasing factors that stimulate other glands to release their own hormones.
• Endocrinologists are medical specialists who diagnose and treat disorders related to hormonal imbalances and diseases affecting the endocrine glands.
• The endocrine system is responsible for regulating various bodily processes such as growth and development, metabolism, reproduction, sleep-wake cycles, stress response, and mood regulation.
• Endocrine System is a "system of checks and balances"
• Thyroid Stimulating Hormone (TSH) controls thyroid function and metabolic rate. It stimulates thyroid gland to release a thyroxine T3 and T4
• Growth Hormone (GH) regulates body composition, bone density, muscle mass, and cellular regeneration.
• Adrenocorticotropic Hormone (ACTH) regulates cortisol production and stress response.
• Growth Hormone (GH) promotes cell division and growth during childhood and adolescence.
• Adrenocorticotropic Hormone (ACTH) promotes cortisol production from the adrenal cortex.
• Adrenocorticotropic Hormone (ACTH) regulates cortisol production and helps with stress management.
• Follicle-Stimulating Hormone (FSH) stimulates sperm production in males and egg maturation in females.
• Luteinizing Hormone (LH) triggers ovulation in women and testosterone production in men.
• Prolactin stimulates milk production in females.
• Cortisol is produced by the adrenal glands and plays a role in regulating blood sugar levels, reducing inflammation, and managing stress.
• Pituitary Gland is a very small but very powerful "master gland" that controls the release of hormones from other glands
• Hypothalamus starts releasing and inhibiting hormones. Link between endocrine and nervous system.
• Oxytocin soothes muscle around glands
• Oxytocin is the love hormone
• Antidiuretic Hormone helps regulate water balance in body
• Thyroid Gland is the speed of metabolism or metabolic rate
• Thyroxine regulates the rate of metabolism
• Hyperthyroidism - weight loss
• Hypothyroidism - weight gain
• Calcitonin - regulating level of calcium in blood by decreasing it
• Calcitonin ; Parathyroid Gland
• Parathyroid Gland - increases body calcium level. Regulator of calcium and phosphorus
• Adrenal Gland aka Suprarenal gland
• Adrenal Gland regulates body's stress response
• danger is perceived by amygdala and sends signal to hypothalamus and pituitary gland that sends ACTH to adrenal gland
• Adrenaline/ Epinephrine - person is stressed, excited, and in pain. fight or flight response. Increased rate of blood circulation, breathing and metabolism
• Insulin; Cortisol
• Cortisol - relieve stress, increase blood glucose levels, increase blood pressure, increase blood sugar levels.
• Cortisol - primary stress hormone and anti prolactin hormone
• Aldosterone - regulation of blood pressure. Increase amount of salt and potassium.
• Pancreas - beneath stomach. Convert food to fuel
