Endocrine System Labeling Flashcards

Study Notes

Endocrine System Components

Hypothalamus: A crucial part of the brain that regulates body temperature, hunger, moods, and the sleep-wake cycle; produces hormones that control the pituitary gland.
Pituitary Gland: Known as the "master gland," it controls other endocrine glands and regulates vital functions such as growth, metabolism, and reproductive processes.
Parathyroid Gland: Small glands located behind the thyroid that regulate calcium levels in the blood and bone metabolism through the secretion of parathyroid hormone.
Kidney: Apart from filtering blood and producing urine, kidneys secrete hormones like erythropoietin that stimulate red blood cell production and renin that helps regulate blood pressure.
Testis (in male): Male reproductive glands that produce testosterone and spermatogenesis; critical for male sexual development and reproductive functions.
Pineal Gland: A small, pea-shaped gland in the brain that produces melatonin, which regulates sleep-wake cycles and circadian rhythms.
Thyroid Gland: Regulates metabolism, energy generation, and growth by releasing thyroid hormones (T3 and T4) and calcitonin, which lowers blood calcium levels.
Thymus: Located in the upper chest, this gland is essential for developing T-cells (a type of white blood cell) important for immune function; shrinks with age.
Adrenal Gland: Situated on top of each kidney; produces corticosteroids, adrenaline, and noradrenaline, influencing stress response and regulating metabolism and immune responses.
Pancreas: Functions as both an endocrine and exocrine gland; secretes insulin and glucagon to regulate blood sugar levels and produces digestive enzymes.
Ovary (in female): Female reproductive glands responsible for producing eggs (oocytes) and hormones like estrogen and progesterone, which regulate the menstrual cycle and pregnancy.
