Hormones of the Body

There are a significant number of hormones of the body, all which hold a very special role assigned to in the body.

List of hormones in the body and their primary function

Hypothalamus – Endocrine Gland
Thyrotropin-releasing hormone (TRH)
Stimulation of the thyroid gland results in the synthesis of T3 & T4 hormones

Corticotropin-releasing hormone (CRH)
Stimulation of the adrenal gland cortex secretes glucose and mineral corticoids

Growth hormone-releasing hormone (GHRH)
Stimulation produces growth hormone

Growth hormone inhibitory hormone (GHIH) (somatostatin)
This hormone inhibits the release of growth hormone, TSH and insulin d

Gonadotropin-releasing hormone (GnRH) is also referred to as luteinising hormone releasing hormone.
Controls the release of FSH and LH

Dopamine or prolactin-inhibiting factor (PIF)
Inhibition of prolactin secretion.

Anterior Pituitary Gland – Endocrine Gland
Growth hormone
Growth is stimulated by the anterior pituitary gland

Thyroid-stimulating hormone (TSH)
This hormone releases T3 & T4

Adrenocorticotropic hormone (ACTH)
Stimulates adrenal cortex to produce

Prolactin
Stimulates milk formation

Follicle-stimulating hormone (FSH)
Stimulation results in the production of sperms in male and Ova in females.

Luteinizing hormone (LH)
Forms the ova in females & produces testosterone

Posterior Pituitary Gland – Endocrine Gland
Antidiuretic hormone (ADH) (vasopressin)
Limits the water expulsion by the kidney. Constricts blood vessels and produces a rise in blood pressure

Oxytocin hormone
Affects women who are pregnant with the onset of contractions when the baby is ready to be delivered. Mood enhancer often called the Love Hormone

Intermediate Pituitary Gland – Endocrine Gland
Melanocyte Stimulating Hormone
Stimulates the production of melanin in the skin which acts as a buffer against UV damage and causes skin pigmentation.

Thyroid Gland - Endocrine Gland
Thyroxine (T4) and triiodothyronine (T3)
Regulation of body metabolism and temperature

Calcitonin (Vitamin D)
Reduction of blood calcium, deposition in bone, decrease in intestinal absorption and expulsion by the kidney.

Adrenal Cortex – Endocrine Gland
Cortisol
Increases blood sugar levels and suppress immune system

Aldosterone

DHEA

Adrenal Medulla – Endocrine Gland
Norepinephrine, epinephrine

Pancreas – Endocrine Gland
Insulin (ő≤ cells)
Helps absorb glucose from blood to tissue and also release from liver

Glucagon (őĪ cells)
Helps absorb glucose into liver to form glycogen

Somatostatin
When insulin and glucagon levels are at higher levels than normal, the secretion of somatostatin maintains  glucose and salt balance in the blood.

Parathyroid hormone PTH
Parathyroid

Testes – Endocrine Gland
Testosterone
Builds muscles, give muscle character and also stimulate formation of sperms

Ovaries and Placenta – Endocrine Gland
Oestrogens
Development of female reproductive system.

Progesterone
Menstruation, Aids zygote implantation, Lactation & sexual drive

Human chorionic gonadotropin (HCG)
Human somatomammotropin

Kidney РEndocrine Organ
Renin
Helps maintain blood volume and there by blood pressure

1,25-Dihydroxycholecalciferol
Rises Blood calcium levels kidney/nephron

Erythropoietin
Stimulates formation of red blood cells.

Heart Muscle РEndocrine Organ
Atrial natriuretic peptide (ANP)
balance of water, sodium, potassium and fat in body

Stomach РEndocrine Organ
Gastrin
To secrete gastric juice

Small Intestine РEndocrine Organ
Secretin
Water levels and water balance in body

Cholecystokinin (CCK)
Stimulates fat and protein digestion in the intestine.

Adipose (Fat Cells)- Endocrine Organ
Leptin
Regulates energy balance. Inhibits hunger if needed

Gastro intestine РEndocrine Organ
Ghrelin
Stimulates hunger Gastro intestine

Endocrine diseases are typically a result of a hormonal imbalance which often can be rectified by hormonal supplementation. It is important to know your own body and to be aware of what symptoms appear – particularly as you age, so you can alert your medical doctor and obtain hormone testing.
