Study Notes
Pituitary Gland
- Secretes key hormones: Growth Hormone (GH), Adrenocorticotropic Hormone (ACTH), Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), Antidiuretic Hormone (ADH), Prolactin (PRL), and Oxytocin.
- Growth Hormone (GH) stimulates overall growth.
- ACTH regulates the activity of the adrenal cortex.
- LH is responsible for controlling sex hormone release.
- FSH promotes the production of eggs in females and sperm in males.
- ADH helps in retaining water in the kidneys to regulate hydration.
- Prolactin (PRL) is essential for milk production.
- Oxytocin triggers uterine contractions during childbirth.
Thyroid
- Produces hormones T3 and T4, crucial for energy metabolism.
- Calcitonin helps regulate calcium levels by lowering blood calcium from bones.
Adrenal Gland
- Releases hormones such as Epinephrine, Aldosterone, Cortisol, and Sex Hormones.
- Epinephrine increases heart rate and prepares the body for fight-or-flight responses.
- Aldosterone regulates sodium and potassium balance to maintain blood pressure.
- Cortisol assists in the breakdown of fats and proteins for energy.
- Sex Hormones are vital for male and female reproductive functions.
Testes
- Produce Testosterone, which is essential for male development and reproductive functions.
Pineal Gland
- Secretes Melatonin, which regulates sleep cycles and circadian rhythms.
Parathyroid Gland
- Produces Parathyroid Hormone (PTH), essential for regulating blood calcium levels.
Thymus
- Produces Thymosins that are important for immune system functions.
Pancreas
- Produces Insulin and Glucagon to regulate blood glucose levels.
- Insulin lowers blood glucose, facilitating cellular uptake.
- Glucagon (from alpha cells) raises blood glucose levels when necessary.
Ovaries
- Produce Estrogen, which is crucial for female development and reproductive health.
