The Endocrine System: Glands and Their Hormones

• The endocrine system: composed of different glands that secrete hormones that regulates metabolism, growth and development, mood, and reproduction
• Produces hormones that stimulate growth, and control the functions of other glands; located at the base of the brain

  • pituary gland
• Hormones of the pituitary gland

  Oxytocin, Growth Hormones (GH), Prolactin (PRL), Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Adrenocorticotrophic hormone (ACTH), Antidiuretic hormone (AH), Thyroid Stimulating Hormone (TSH).
• produces hormones that regulate body metabolism and storage of calcium in bones; located in front of the neck and below the voice box

  • thyroid gland
• hormones of thyroid; thyroid hormone
• Produces hormones that control the calcium levels in your body, and normalizes bone growth; located in the neck

  • parathyroid gland
• hormones of parathyroid; parathormone
• produces hormones that enable the body to produce T cells before puberty; in front of the heart

  • thymus gland
• produces hormones that affects metabolism, immune system, and blood pressure, stress reaction; on top of the kidneys

  • adrenal gland
• hormones of adrenal gland; adrenaline
• Produce hormones that regulate blood sugar levels; behind the stomach

  • pancreas
• hormones of pancreas; insulin and glucagon
• produces a hormone that regulates the biological clock in some animals; in the brain

  • pineal gland
• hormones of pineal; melatonin
• produces hormones that influence development of the secondary female sexual characteristics, and maturation of the egg cells and ovulation; In the pelvic area

  • ovaries
• hormones of the ovaries; estrogen and progesterone
• • Are organic substances released

  by the glands of the endocrine system directly into the bloodstream.

  • hormones
• • Capable of changing the

  physiological and metabolic behaviors of their target cells to maintain homeostasis.

  • hormones
• • Released from ovary cells around developing eggs.
  • Regulates menstrual cycle and supports pregnancy.
  • estrogen
• • Released from “corpus luteum” in ovaries.
  • Prepares the uterus lining (endometrium) to receive the fertilized egg.
  • Stimulates blood supply to the lining of the uterus.

  FACILITATES THE

  IMPLANTATION

  OF THE FERTILIZED EGG

  • progesterone
• released from pituitary: FSH AND LH
• Follicle-stimulating hormone (FSH)

  • Essential to pubertal development as it stimulates estrogen production and facilitates the maturation of the ovarian follicles.
  • Stimulates follicular reproduction
• Luteinizing hormone (LH)

  • facilitate ovulation by causing the release of the egg contained in the follicle
  • facilitates ovulation
• Hormonal imbalance will occur if the organs and hormones of your body do not produce the right amount of chemicals needed which in turn may lead to some dysfunctions.

  • endocrine system disorder
• A disease that happens when the mineral density of the bone is reduced making it brittle and porous. Parathyroid hormone secretion is one of the possible causes of this disease.

  • osteoporosis
• An abnormal enlargement of the thyroid gland. It results from the underproduction or overproduction of thyroid hormones.

  • goiter
• is a disorder that happens during childhood when there is abnormal increase in height associated with too much secretion of growth hormones.

  • gigantism
• is a condition wherein the production of growth hormones in the pituitary gland is insufficient resulting in short stature.

  • dwarfism
