Special Senses (Chemical Senses : Smell And Taste)

Front 1

Chemoreceptors

Back 1

Receptors for taste and olfaction because they respond to chemicals in solution

Front 2

Olfactory receptors

Back 2

Receptors for sense of smell

Front 3

Olfactory receptor cells

Back 3

Neurons equipped with olfactory hairs (long cilia that protrude from the nasal epithelium and bathed with mucus secreted by glands )

Front 4

Olfactory filaments

Back 4

Bundle of axons of olfactory neurons that collectively make up the olfactory nerve

Front 5

Taxare

Back 5

Taste comes from the latin word___ which means to touch, estimate/judge

Front 6

Papillae

Back 6

Dorsal tongue surface is covered with small peglike projections or?

Front 7

Circumvallate papillae

Back 7

Taste buds are found on the sides of the large round vallate papillae or?

On the top of the more numerous fungiform papillae and in the foliate papillae on the sides of the tongue

Hint 7

Front 8

Gustatory cells

Back 8

Located in the taste buds that are epithelial cells (is a specific receptor cell) that respond to chemicals dossolved in the saliva

Front 9

MucUs layer and olfactory hairs

Back 9

Part of the olfactory mucosa include the

Front 10

Gustatory hairs

Back 10

Long microvilli protrude through the taste pore; when stimulated they depolarise and impulses are transmitted to the brain

Front 11

Facial nerve(VII) anterior part of the tongue, Glossopharyngeal nerve and vagus nerve

Back 11

Three cranial nerves that carry taste impulses from the various taste buds to the gustatory cortex.

Front 12

Basal cells

Back 12

Found in the deeper regions of the taste buds they are the cells that replace when tongue is burned by hot food

Front 13

Sweet receptors

Back 13

Taste sensation that respond to substances such as sugar, saccharine, some amino acids and some lead salts

Located on the tip of tongue

Front 14

Sour receptors

Back 14

A taste sensation that respond to hydrogen ions or the acidity of the solution

Located on the sides of the tongue

Front 15

Bitter receptors

Back 15

Responds to Alkaloids

Located at the back of the tongue

Front 16

salty receptors

Back 16

Responds to Metal ions in solution

Located at the tip of the tongue

Front 17

Umami

Back 17

Taste discovered by the Japanese by the amino acid glutamate, respomsible for beef taste of steak and a monosodium glutamate a food additive

Located on the pharynx
