Explanation

Image shows name and functions of Endocrine glands

Image shows name and functions of Endocrine glands and secreted hormones

Endocrine gland

Hormone

Functions

Hypothalamus

Thyrotrophin releasing hormone

Stimulates release of thyroid stimulating hormone (TSH)

Hypothalamus

Somatostatin

prevents release of hormones such as growth hormone

Hypothalamus

Growth Hormone Releasing Hormone (GHRH)

Stimulates release of growth hormone (GH)

Anterior pituitary

Thyroid stimulating hormone (TSH)

Stimulates release of thyroxin

Anterior pituitary

Follicle stimulating hormone (FSH)

Females: promotes development of eggs and follicles in the ovary prior to ovulation Males: promotes production of testosterone from testis

Anterior pituitary

Adrenocortico-trophic hormone (ACTH)

Stimulates the adrenal glands to produce mainly cortisol

Posterior pituitary

Vasopressin (anti-diuretic hormone, ADH)

Acts to maintain blood pressure by causing the kidney to retain fluid and by constricting blood vessels

Posterior pituitary

Oxytocin

Causes ejection of milk from the milk ducts and causes constriction of the uterus during labor

Thyroid gland

Thyroxin (T4)

regulate the body’s metabolic rate

Parathyroid glands

Parathyroid hormone (PTH)

Increases blood calcium levels

Pancreas

Insulin

to lower blood glucose levels

Ovary

Estrogens

Acts to promote development of female primary and secondary sexual characteristics.

Testis

Testosterone

Promotes the development of male sexual characteristics including sperm development
