Endocrine system

Endocrine system

Regulates body activities through the use of hormones

Endocrine glands

Goes directly into bloodstream and transported through body

Exocrine glands

In ducts used to release substances (sweat, tears, or enzymes)

Pituitary gland anterior hormones

Growth hormone, melanocyte stimulating hormone, prolactin, adrenocorticotropic hormone, thyroid- stimulating hormone, follicle stimulating hormone , and luteinizing hormone

Pituitary gland posterior glands

Oxytocin and anti diuretic hormone

Thyroid gland

Thyroxin and triiodothyronine/ calcitonin

Parathyroid glands

Parathyroid hormone

Adrenal glands; medulla

Epinephrine and norepinephrine

Adrenal glands; cortex

Mineralocorticoids (aldosterone)→ glucocorticoids (cortisol, corticosterone and cortisone) → sex hormones (androgens and estrogens)

Pancreas

Glucagon and insulin

Gonads

Estrogens and testosterone

Pineal gland

Melatonin

Thymus gland

Thymosin

Adrenocorticotropic hormone stimulates

The cortex of the adrenal glands

Thyroid stimulating hormone stimulates

The thyroid

Pituitary gland

Master Gland in base of brain divided into two lobes

Growth hormone

Regulates growth of body

Adrenocorticotropic hormones

Stimulates the adrenal cortex

Follicle stimulating hormone and luteinizing hormone

Stimulates the sex hormones

Luteinizing hormone

Releases egg from ovary during ovulation. Let go

Follicle stimulating hormone

Stimulates development of egg/sperm

Prolactin

Stimulates milk production

Oxytocin

Stimulates contraction of uterus during labor and release of milk

Antidiuretic hormone

Conserves water

Melanocyte stimulating hormone

Stimulates the melanocytes for skin pigmentation

Hypothalamus

Commander in chief

Thyroid gland

Largest gland.

Calcitonin

Reduces calcium

Thyroxin and triiodothyronine

Control catabolic metabolism

Parathyroid hormone

Increases calcium

Glucagon

Raises blood sugar

Insulin

Lowers blood sugar

Estrogen

Stimulates development of female sex characteristics

Melatonin

Regulates body rhythms such as sleep cycles and mood

Thymosin

Stimulates the maturation of thymus lymphocytes

Epinephrine and norepinephrine

Adrenal Medulla. Epinephrine increases heart rate, BPM during flight or fight response to deal with stress. Norepinephrine lowers.

Aldosterone

Adrenal cortex. Sodium and potassium are secreted for body regulation.

Cortisol

Adrenal cortex. Aids body during stress by increasing glucose levels.

Sex hormones (androgens and estrogen)

Stimulate sex cell development

Insulin + glucose

=glycogen

Glucagon + glycogen

= glucose

Pituitary gland

Hypophysis

Anterior lobe

Adenohypophysis

Posterior lobe

Neurohypophysis
