• mechanoreceptors

The process by which the brain causes a sensation to seem to come from the stimulated receptors is called _________________.

• perception

• illusion

• sensation

• interpretation

Pain receptors:

• B) adapt rapidly.

• C) are among the most specialized receptors.

• D) are widely distributed in the nerve tissues of the brain.

The following structures that contain pain receptors are:

• meninges on the surface of the brain only.

• blood vessels in the brain only.

• meninges on the surface of the brain and blood vessels in the brain.

• neither meninges on the surface of the brain nor blood vessels in the brain.

• nervous tissue in the brain.

• E) sensory deprivation.

Olfactory receptor cells are best described as
