| Question | Answer |
|---|---|
| A ductless gland that secretes hormones directly into the interstitial fluid, from which they diffuse into the bloodstream. | Endocrine glands |
| Referring to a secreted molecule that acts on a neighboring cell. | Paracrine |
| Referring to a secreted molecule that acts on the cell that secreted it. | Autocrine |
| A molecule that is secreted by a neuron, travels in body fluids, and acts on specific target cells, changing their functioning. | Neurohormones |
| The linkage of a mechanical, chemical, or electromagnetic stimulus to a specific cellular response. | Signal transduction |
| One of a group of modified fatty acids secreted by virtually all tissues and performing a wide variety of functions as local regulators. | Prostaglandins |
| A hormone secreted by pancreatic alpha cells that raises blood glucose levels. It promotes glycogen breakdown and release of glucose by the liver | Glucagon |
| A portion of the pituitary that develops from nonneural tissue; consists of endocrine cells that synthesize and secrete several tropic and nontropic hormones. | Anterior pituitary |
| A hormone that has an endocrine gland or cells as a target. | Tropic hormone |
| A tropic hormone that is produced and secreted by the anterior pituitary and that stimulates the production of eggs by the ovaries and sperm by the testes. | Follicle-stimulating hormone (FSH) |
| A hormone that is produced and secreted by the anterior pituitary and that has both direct (nontropic) and tropic effects on a wide variety of tissues | Growth hormone (GH) |
| One of four small endocrine glands, embedded in the surface of the thyroid gland, that secrete parathyroid hormone. | Parathyroid glands |
| A hormone secreted by the parathyroid glands that raises blood calcium level by promoting calcium release from bone and calcium retention by the kidneys. | Parathyroid hormone (PTH) |
| Any of a class of neurotransmitters and hormones, including the hormones epinephrine and norepinephrine, that are synthesized from the amino acid tyrosine. | Catecholamines |
| A steroid hormone secreted by the adrenal cortex that regulates salt and water homeostasis. | Mineralocorticoids |
| Any steroid hormone with progesterone-like activity. | Progestin |
| A hormone that is secreted by the pineal gland and that is involved in the regulation of biological rhythms and sleep. | Melatonin |
