Endocrine System

System of ductless glands that secrete hormones

Hormones in the Endocrine System are known as

Hormones in the Endocrine System circulate in the

Respond to the hormones for which they have receptors

Pituitary Gland, Pineal Gland, Thyroid Gland, Parathyroid Gland, Adrenal Glands

2 Adrenal Glands

Pancreas, Thymus, Gonads, Hypothalamus

Sits in the hypophyseal fossa; depression in sella turcica or sphenoid bone

Pituitary gland secretes _____

Anterior Pituitary

Posterior Pituitary

TSH, ACTH, FSH, LH, GH, PRL, MSH

ADH, Oxytocin

TSH, ACTH, FSH, LH; Regulate functions of other hormones

a serotonin derived hormone which modulates sleep patterns; a small endocrine gland in the brain; situated beneath the back part of the corpus callosum

Produced by the pineal gland

Produces hormones that regulate the body's metabolic rate, controlling heart, muscle and digestive function, brain development, and bone maintenance

Produced by the Thyroid Gland; Basal metabolic hormone.

Increases blood Ca+++ concentration when it gets too low

Produces hormones including adrenaline and steroids, aldosterone and cortisol

Also known as suprarenal glands

Secretes hormones that regulate the level of glucose in the blood, and prevents the release of insulin and glucagon

Main hormones secreted by endocrine gland in the pancreas

Prevents the release of insulin and glucagon; Works to stop the pituitary gland from releasing certain hormones, including growth hormones and TSH.

Regulate level of glucose in the blood

a hormone that helps regulate the amount of sugar, or glucose, in the blood.

Secretes thymosin, thymopoietin, and thymulin

Hormone that programs T lymphocytes.

The three major thymus hormones are thought to reside in the ____ of the thymus epithelial cell

Produced by human gonads

Testes and Ovaries

Primary hormones produced by gonads

Primary androgen that plays a critical role in the development of the primary and secondary male sex characteristics, as well as in spermatogenesis.

Primary female hormones, which are responsible for egg development, the menstrual cycle, and breast development.

Endocrine Glands that secretes Corticotropin-releasing hormone (CRH), Gonadotropin-releasing hormone (GnRH), Thyrotropin-releasing hormone (TRH), Somatostatin, Oxytocin, and Vasopressin

Involved in the body’s response to both physical and emotional stress. It signals the pituitary gland to produce

Triggers production of cortisol, an important stress hormone

Causes the pituitary gland to produce important reproductive hormones, such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH)

Stimulates the pituitary gland to produce thyroid-stimulating hormone (TSH)

Plays an important role in the function of many body parts, such as the muscles, heart, and gastrointestinal tract; This is one example of a tropic hormone.

This hormone controls many important behaviors and emotions, such as sexual arousal, trust, recognition, and maternal behavior.

Also called antidiuretic hormone (ADH) - regulates water levels in the body. When vasopressin is released, it signals the kidneys to absorb water.; Hypothalamic hormone important in regulating water balance.

Involved in helping to regulate levels of calcium and phosphate in the blood, opposing the action of parathyroid hormone.

Acts antagonistically to insulin; produced by the same endocrine organ. B

Example of short-term stress hormone

Adrenal cortex hormone involved in regulating salt levels of body fluids.

A hormone necessary for milk production.

This hormone plays in the regulation of ovarian cycle.

Adrenocorticotropic Hormone

Thyroid-Stimulating Hormone

Follicle-Stimulating Hormone

Luteinizing Hormone

Growth Hormone

Prolactin

Melanocyte-Stimulating Hormone

Antidiuretic Hormone
