glandSpecialized organ of the body that manufactures and secretes enzymes, hormones, or other chemicals. In animals, glands vary in size from small (for example, tear glands) to large (for example, the pancreas), but in plants they are always small, and may consist of a single cell. Some glands discharge their products internally, endocrine glands, and others externally, exocrine glands. Lymph nodes are sometimes wrongly called glands. How to thank TFD for its existence?

This pea-size "master gland" secretes hormones that control most of the other endocrine glands. These seven centers are located along the spinal cord where there is an increase in volume of nerve ganglia and plexus plus endocrine glands. Endocrine disruptors are chemicals that interfere with the action of hormones produced by the endocrine glands. |
