There are 34 terms for the letter 'E'.

Capacity to produce a desired treatment effect.
Electrocardiogram (EKG,ECG)
A graphic record of the heart's action produced by an electrocardiograph and used for diagnostic purposes.
Device that records the electrical activity of the heart over time.
Substance that dissociates into ions (charged particles) in solution, making it capable of conducting electricity.
Cell signaling performed by the secretion of chemicals which are carried by the blood and tissue fluids to target cells.
Endocrine gland
Ductless glands that regulate physiological functions in the body by secreting hormones directly into the bloodstream.
Endocrine system
System of glands that release hormones directly into the circulatory system to help to control metabolic activity. The endocrine system controls slow, long-lasting responses to internal stimuli.
Endocrinologist (Endocrinologists)
Doctor trained in diagnosis of diseases which affect your glands and in treating complex conditions that involve many systems within the body.
The science of hormone function which includes the study of conditions such as: diabetes, thyroid disease, metabolic disorders, menopause, osteoporosis, hypertension, cholesterol (lipid) disorders, and infertility.
Endocytosis (Endocytic)
A process of cellular ingestion by which the plasma membrane folds inward to bring substances into the cell.
Produced or synthesized within the organism or system.
Any of several morphine-like peptides naturally produced in the brain which bind to certain neuron receptors and have the effect of diminishing pain.
Endothelial cells
Cells which line the entire circulatory system, from the heart to the smallest capillary, and reduce turbulence in the blood flow.
Presence of endotoxins in the blood, increasing risk of hemorrhages, necrosis of the kidneys, and shock.
A protein (or protein-based molecule) that speeds up a chemical reaction in a living organism.
Ependymal cell
Cell which lines the ventricles (fluid-filled spaces in the brain).
A rare type of glioma that develops from the ependymal cells in the brain and from the central canal of the spinal cord. Ependymomas can be found in any part of the brain or spine and in children are more common in the cerebellum.
Health-related event affecting many persons at the same time.
Relating to the study of the causes, distribution, and control of disease in populations.
Epidemiological study
Statistical study on human populations in which the aim is to link human health effects to a specified cause.
Scientist who studies the frequency and distribution of disease within populations and environments.
Study of diseases in populations of humans (or other animals) to determine associated risk and protective factors.
The upper (or outer) layer of the two main layers of cells that make up the skin.
Epithelial cells
Cells located throughout the body, a portion of which are used for secretion and make up specific parts of the body referred to as glands.
Tissue composed of a layer of cells.
Having equal effects or capacities.
Ergocalciferol (Calciferol,Vitamin D2)
A vitamin D-like, once-patented drug that is derived from fungal and plant sources by activating ergosterol with ultraviolet light and is not naturally present in the human body.
A device which measures the amount of energy or work performed.
Precursor to ergocalciferol. A component of fungal cell membranes which serves the same function in plants that cholesterol does in animals.
Steroid hormone present in both men and women, usually at higher levels in women of reproductive age.
Cause of a disease or abnormal condition.
Eukaryote (Eukaryotic)
An organism, such as an animal, plant, fungus, or protist, whose cells are organized into complex structures enclosed within membranes.
Exocrine gland
Duct glands that secrete enzymes into ducts. Typical exocrine glands include sweat glands, salivary glands, mammary glands, stomach, prostrate, and liver.
Experimental autoimmune encephalomyelitis (EAE)
An experimental model of brain inflammation that is similar to the inflammation that occurs in multiple sclerosis (MS).
