Conductive deafness. Deafness caused by inadequate conduction of sound into the inner ear. Diseases or obstructions in the outer or middle ear cause conductive hearing losses. Specifically, a conductive hearing loss is the impairment of hearing due to a failure of sound pressure waves to reach the cochlea through normal air conduction channels; at the…

Results from an accumulation of excess ear wax (cerumen) which becomes impacted in the external ear canal preventing sound waves from reaching the ear drum (tympanic membrane), perceptive deafness. Conductive hearing loss occurs when there is an impairment in the transmission of sound from the outer to the inner ear. This can be caused by…

In physiology, blocking of nerve impulses that are needed to produce proper heart action.  

A rubber, latex, or animal skin sheath that is placed over the penis to prevent sperm from reaching the egg and resulting in conception. A rubber sheath worn on the penis during intercourse as a contraceptive and also as a protection against sexually transmitted disease. The form of birth control that uses a thin, stretchable…

The stimulus that is paired with the unconditioned stimulus and subsequently acquires the capacity to evoke a response similar to the one made to the unconditioned stimulus. A stimulus that gives rise to a conditioned response.  

The response (behavior) that is evoked by the conditioned stimulus after conditioning has taken place.  

An initially neutral stimulus that acquires reinforcing properties through association with another stimulus that is already reinforcing.  

The process by which a person is conditioned not to respond to some stimulus that formerly produced a response.  

Perceived stress that results from having learned to fear specific situations.  

In optics and physics, a lens system of one or more elements that gathers light waves, converging them on the subject. An arrangement of lenses beneath the stage of a microscope. It can be adjusted to provide correct focusing of light on the microscope slide. A device used to liquefy gases or vapors, or rarely…
