Efferent
A raised surface or part.
Elevation
Excessive leanness; a wasted condition resulting in sunken surfaces of the face.
Emaciation
A severe skin irritation due to prolonged exposure to formaldehyde or other embalming chemicals.
Embalmer’s Eczema
Any abnormal mass carried freely in the bloodstream; maybe a blood clot, bubbles of air, mass of fat, or clumps of cells.
Embolus
A prominence or projection, especially of a bone.
Eminence
The layer that lines the inner surface of the heart wall; consists of endothelium and areolar connective tissue.
Endocardium
Secreting into the blood or tissue fluid rather than into a duct; opposite of exocrine.
Endocrine
Mucous membrane lining the uterus.
Endometrium
The simplest squamous epithelium that lines the walls of the heart, blood vessels, and lymphatic vessels.
Endothelium
The removal of an entire mass or part, especially a tumor of the eyeball, without rupture.
Enucleation
An organic catalyst produced by living cells and capable of autolytic decomposition.
Enzyme
The outermost layer of skin.
Epidermis (Cuticle, Scarf Skin)
Bleeding from the nose.
Epistaxis
Comma-shaped structure in the scrotum adjacent to the testis; contains a duct in which the sperm mature.
Epididymis
A leaf-shaped piece of elastic cartilage that extends from the posterior surface of the tongue to the larynx; covers the opening of the larynx during swallowing.
Epiglottis
Ends of a long bone.
Epiphyses
A primary tissue that covers body surfaces and lines body cavities; its cells are arranged in.
Epithelium
When mature, this kind of cell is literally a sac of hemoglobin (oxygen carrying protein) covered by a plasma membrane.
Erythrocyte (Red Blood Cell)
Female sex hormones.
Estrogens
A term applied to the external secretion of a gland.
Exocrine
Glands that secrete onto body surfaces or into body cavities; except for the one-celled goblet cells, all of these glands have ducts.
Exocrine Glands
Loss of blood to the point where life can no longer be sustained.
Exsanguination
Straightening out a body part such as the arm.
Extension
Exterior; the opposite of medial or internal.
External
The lateral, outer opening of the external auditory canal.
External Auditory Meatus
Outside a cell.
Extracellular
Outside the blood vascular system.
Extravascular
Originating outside an organ or part.
Extrinsic
The superficial hairs covering the superciliary arches.
Eyebrows (Supercilium)
Two movable flaps of skin which cover and uncover each eyeball.
Eyelids (Palpebrae)
The bony region containing the eyeball; the orbital cavity.
Eye Socket (Orbital Cavity)
Sheet of connective tissue.
Fascia
Organic compound containing carbon, hydrogen and oxygen; chemically, a triglyceride ester, composed of glycerol and fatty acids.
Fat
A product of decomposition of fats.
Fatty Acids
Fibrous insoluble protein formed during blood clotting; takes the form of a fiber network.
Fibrin
Passage of a solution or suspension through a membrane or filter, with the purpose of holding back the larger particles.
Filtration
Groove.
Fissure
Bending a body part such as the arm.
Flexion
A hold, small opening; example, ______ magnum of the occipital bone.
