False.

The opening to a taste bud is called a __________.

Taste pore

The primary olfactory cortex for interpreting smell is located in the _____________ of the cerebrum.

Temporal lobe

Substances that stimulate taste cells bind with _____________ sites on the surface of taste hairs.

receptor

Salt receptors are mainly stimulated by ionized inorganic _____________.

salts

Olfactory sensations usually fade rapidly as a result of:

sensory adaption.

The ___________ of a taste cell are its sensitive part.

taste hairs

The primary olfactory interpretation center is located in the:

temporal lobe of the cerebrum.

Before gaseous substances can stimulate the olfactory receptors, they must be dissolved in ________ that surrounds the cilia.

Mucus

A chemical would be considered _________ if a person lacks a particular receptor site on the cilia of the olfactory neurons.

odorless

Receptors cells for taste are located:

on the tongue, oral cavity, and pharynx.

Alkaloids usually have a ______________ taste.

Bitter

The axons of olfactory receptors pass through small openings in the _________ of the ethmoid bone.

Cribiform plate

Taste interpretation occurs in the __________ of the cerebrum.

Insula

Chemoreceptors

Modified sensory neurons that are stimulated by various chemicals dissolved in liquids. Olfaction and taste are dependent on this.

True/False The facial, glossopharyngeal, and vagus cranial nerves conduct impulses from taste receptors to the brain.

True

Which of the following is not considered a recognized taste? a. mint b. salty c. sweet d. umami

a. mint

Sour receptors are mainly stimulated by __________.

acids

Sour sensations are produce from:

acids.

Olfactory receptor cells

actually neurons surrounded by pseudostratified columnar epithelial cells (supporting cells). Their apical ends are covered with cilia (olfactory hairs), embedded in the mucus of the superior nasal cavity.

The distal ends of the olfactory neurons are covered with hairlike:

cilia

The facial, _____________, and vagus cranial nerves conduct impulses related to the sense of taste.
