Taste & Smell

Most taste buds are found between these small bumps across the main surface of the tongue:

• fungiform papillae

• sulcus papillae

• lingual papillae

• acoustic papillae

The bone through which olfactory neurons pass from the nasal cavity to the brain:

• temporal

• ethmoid

• mandible

• frontal

The kind of cell that actually senses molecules dissolved in saliva, but dous not transmit those signals to the brain:

• gustatory epithelial receptors

• fungiform epithelial receptors

• auditory epithelial receptors

• axillary epithelial receptors

The part of the brain that receives some information about smell and associates it with emotional responses:

• hippocampus

• limbic system

• cerebellum

• brain stem

Part of the temporal lobe of the cerebrum that receives and initially processes signals about smell:

• visual cortex

• gustatory cortex

• olfactory cortex

• auditory cortex

Our sense of taste, or transduction of chemical signals in the mouth (mostly) to perceptible action potentials:

• gustation

• audition

• photoreception

• hyperaction

This taste is sensed when hydrogen ions dissolved in saliva enter open proton channels in specific gustatory epithelial receptors:

• sour

• sweet

• starchy

• bitter

Our sense of smell, or transduction of chemical signals in our nasal passage to perceptible action potentials:

• gulation

• photoreception

• olfaction

• audition

This taste is sensed when sodium ions dissolved in saliva enter open sodium channels in specific gustatory epithelial receptors:

• salty

• sour

• umami

• bitter

A small extension of the cell membrane from a gustatory epithelial cell that reaches through the taste pore of a taste bud:

• gustatory hair

• olfactory cilium

• gustatory villus

• auditory hair
