Study Notes
Endocrine System
Overview
- The endocrine system is a network of glands and organs that produce and regulate hormones in the body.
- Hormones are chemical messengers that help control various bodily functions, such as growth and development, metabolism, and reproductive processes.
Glands and Organs
- Pituitary gland: often referred to as the "master gland" because it regulates other endocrine glands.
- Thyroid gland: produces thyroxine (T4) and triiodothyronine (T3), which regulate metabolism.
- Adrenal glands: produce hormones such as adrenaline (epinephrine) and cortisol, which regulate stress response and metabolism.
- Pancreas: produces insulin and glucagon, which regulate blood sugar levels.
- Ovaries (female): produce estrogen and progesterone, which regulate reproductive processes.
- Testes (male): produce testosterone, which regulates reproductive processes.
Hormones
- Insulin: lowers blood sugar levels by facilitating glucose uptake in cells.
- Glucagon: raises blood sugar levels by stimulating glucose release from stored glycogen.
- Adrenaline (epinephrine): stimulates "fight or flight" response, increasing heart rate and blood pressure.
- Cortisol: regulates stress response, metabolism, and immune function.
- Thyroid hormones (T4 and T3): regulate metabolism, growth, and development.
- Estrogen and progesterone: regulate reproductive processes, including menstruation and pregnancy.
- Testosterone: regulates reproductive processes, including sperm production and libido.
Functions
- Metabolism: regulation of metabolic processes, such as energy production and storage.
- Growth and development: regulation of growth and development, including puberty and bone growth.
- Reproductive processes: regulation of reproductive processes, including menstruation, pregnancy, and fertility.
- Stress response: regulation of the body's response to stress, including the "fight or flight" response.
Disorders
- Diabetes mellitus: a condition characterized by high blood sugar levels due to insulin deficiency or resistance.
- Hypothyroidism: a condition characterized by low thyroid hormone levels, leading to slowed metabolism and growth.
- Hyperthyroidism: a condition characterized by high thyroid hormone levels, leading to rapid metabolism and weight loss.
- Cushing's syndrome: a condition characterized by high cortisol levels, leading to weight gain, hypertension, and mood changes.
- Hypogonadism: a condition characterized by low sex hormone levels, leading to reproductive dysfunction and infertility.
