D004543 |
[Paired ducts in the human male through which semen is ejaculated into the urethra.

El Nino-Southern Oscillation
|
D059000 |
[A climate pattern characterized by unusually warm Pacific Ocean water temperatures.
, A climate pattern characterized by unusually cool Pacific Ocean water temperatures.
, El Nino-Southern Oscillation or ENSO is a cycle of extreme alternating warm El Niño and cold La Nina events which is the dominant year-to-year climate pattern on Earth. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific. ENSO is associated with a heightened risk of certain vector-borne diseases.

Elaeagnaceae
|
D031263 |
[A plant family of the order Rhamnales, subclass Rosidae class Magnoliopsida. The plants have a characteristic silvery or rusty-colored sheen, caused by tiny distinctive scales. Flowers have a tubular structure of four sepals. Root nodules host the Frankia (ACTINOMYCETES) nitrogen-fixing symbionts.

Elafin
|
D053492 |
[A secretory proteinase inhibitory protein that was initially purified from human SKIN. It is found in a variety mucosal secretions and is present at high levels in SPUTUM. Elafin may play a role in the innate immunity (IMMUNITY, INNATE) response of the LUNG.

Elapid Venoms
|
D004546 |
[Venoms from snakes of the family Elapidae, including cobras, kraits, mambas, coral, tiger, and Australian snakes. The venoms contain polypeptide toxins of various kinds, cytolytic, hemolytic, and neurotoxic factors, but fewer enzymes than viper or crotalid venoms. Many of the toxins have been characterized.
, Venoms from snakes of the genus NAJA. They contain many specific proteins that have cytotoxic, hemolytic, neurotoxic, and other properties. Like other elapid venoms, they are rich in enzymes. They include cobramines and cobralysins.
, Venom of the king cobra snake (OPHIOPHAGUS HANNAH) that consists primarily of neurotoxins.
, Venoms of sea snakes (HYDROPHIIDAE) found around Pacific islands. The venoms contain fewer enzymes and more neuro- or myotoxins than land snakes. The neurotoxic proteins are similar to elapid small, short, or type I neurotoxins, some of which have been characterized.

Elapidae
|
D017815 |
[A family of extremely venomous snakes which include coral snakes, cobras and sea snakes. They are widely distributed, occurring in the Southern United States, South America, Africa, Southern Asia, Australia, and the Pacific Islands. Like viperids (VIPERIDAE), they have fangs in the front part of the upper jaw which discharge venom that is neurotoxic.

Elasmobranchii
|
D018940 |
[A subclass of cartilaginous fish comprising the SHARKS; rays; skates (SKATES (FISH);), and sawfish. Elasmobranchs are typically predaceous, relying more on smell (the olfactory capsules are relatively large) than sight (the eyes are relatively small) for obtaining their food.

Elastic Cartilage
|
D051472 |
[A type of CARTILAGE whose matrix contains ELASTIC FIBERS and elastic lamellae, in addition to the normal components of HYALINE CARTILAGE matrix. Elastic cartilage is found in the EXTERNAL EAR; EUSTACHIAN TUBE; EPIGLOTTIS; and LARYNX.
] |
|
Elastic Modulus
|
D055119 |
[Numerical expression indicating the measure of stiffness in a material. It is defined by the ratio of stress in a unit area of substance to the resulting deformation (strain). This allows the behavior of a material under load (such as bone) to be calculated.
] |
|
Elastic Tissue
|
D004547 |
[Connective tissue comprised chiefly of elastic fibers. Elastic fibers have two components: ELASTIN and MICROFIBRILS.

|
Elasticity
|
D004548 |
[Resistance and recovery from distortion of shape.
] |
|
Elasticity Imaging Techniques
|
D054459 |
[Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images - eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.

Elastomers
|
D020724 |
[A generic term for all substances having the properties of stretching under tension, high tensile strength, retracting rapidly, and recovering their original dimensions fully. They are generally POLYMERS.
