An organ that makes hormones that are released directly into the blood and travel to tissues and organs all over the body.

• Hormone

• Hypothalmus

• Endocrine Gland

• Pituitary gland

An extracellular substance (as the hormone epinephrine or the neurotransmitter serotonin) that binds to a cell-surface receptor and initiates intracellular activity.

• First Messenger

• Second Messenger

• Hormone

• Target Cell

An intracellular substance (as cyclic AMP) that mediates cell activity by relaying a signal from an extracellular molecule (as of a hormone or neurotransmitter) bound to the cell's surface.

• First Messenger

• Second Messenger

• Hormone

• Target Cell

A lipophilic hormone that passes through the plasma membrane of a cell, binds to an intracellular receptor, and changes gene expression.

• Water soluble

• First Messenger

• Lipid Soluble

• Second Messenger

Amines and proteins that do not passively diffuse through the cell membrane.

• Lipid Soluble

• First Messenger

• Second Messenger

• Water Soluble

A small gland that makes steroid hormones, adrenaline, and noradrenaline. These hormones help control heart rate, blood pressure, and other important body functions.

• Pituitary gland

• Thyroid gland

• Hypothalamus

• Adrenal gland

The area of the brain that secretes substances that influence pituitary and other gland function and is involved in the control of body temperature, hunger, thirst, and other processes that regulate body equilibrium

• Thymus

• Hypothalamus

• Thyroid

• Parathyroid

A tongue-shaped glandular structure involved in the secretion of fluid containing protease, carbohydrase, and lipase, into the duodenum to aid in food digestion, as well as the secretion of insulin and glucagon into the bloodstream in order to regulate sugar levels in blood.

• Pituitary gland

• Pancreas

• Thyroid

• Parathyroid

Four small glands of the endocrine system which regulate the calcium in our bodies.

• Parathyroid Glands

• Thyroid Glands

• Pineal Glands

• Pituitary Gland

A small endocrine gland shaped like a pinecone, located in the epithalamus, and involved in melatonin production.

• Hypothalamus

• Pineal Gland

• Pituitary Gland

• Thymus gland
