Erection, penile
When the penis fills with blood and is rigid. The penis contains two chambers, called the corpora cavernosa, which run the length of the organ, are filled with spongy tissue, and surrounded by a membrane, called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries. The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa. Erection begins with sensory and mental stimulation. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand. The tunica albuginea helps to trap the blood in the corpora cavernosa, thereby sustaining erection. Erection is reversed when muscles in the penis contract, stopping the inflow of blood and opening outflow channels.

EPA
Eicosapentaenoic acid is a polyunsaturated essential fatty acid. OmegaRx fish oil contains 40 percent EPA. EPA enhances the production of "good" eicosanoids and inhibits the production of Arachidonic Acid (AA). The higher the level of EPA in the diet, the more your cells will be induced to produce more good "eicosanoids"; the high levels of EPA also hinder the production of "bad" eicosanoids. EPA promotes good physical well-being, including increased circulation, and promotes a healthy immune system. EPA is also a powerful anti-inflammatory.
Estrogens

Ependymoma
Ependymal tumors are tumors that begin in the ependyma, the cells that line the passageways in the brain where special fluid that protects the brain and spinal cord (called cerebrospinal fluid) is made and stored. There are different kinds of ependymal tumors, which are defined by how the cells look under a microscope.
Esophageal cancer
Esophageal cancer is cancer of the esophagus. The esophagus is a hollow tube that carries food and liquids from the throat to the stomach. When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach. Glands in the lining of the esophagus produce mucus, which keeps the passageway moist and makes swallowing easier. The esophagus is located just behind the trachea (windpipe). In an adult, the esophagus is about 10 inches (25 cm) long.
Epilepsy
Sudden and recurrent disturbances in mental function, state of consciousness, sensory activity, or movements of the body, caused by paroxysmal malfunction of cerebral nerve cells.
