In humans, the sense of taste is conveyed via three of the twelve cranial nerves. The facial nerve (VII) carries taste sensations from the anterior two thirds of the tongue, the glossopharyngeal nerve (IX) carries taste sensations from the posterior one third of the tongue while a branch of the vagus nerve (X) carries some taste sensations from the back of the oral cavity.
There two types of chemoreceptors, direct and distance. Direct focuses mainly on taste, blood, and senosor. Distance focuses on smell and anntannae for some organisms. Peromores would be a type of distance chemoreceptors, smell; a "organic chemical released from one individual that causes a physiological or behavioral changes in another indivial (Perkins 11-24-03)."
For example, the Bombyx mori is a silkworm that uses pheromores in its female in which the male, with two anntannaes that have over 20,000 receptors, detects the location of the female from afar. See also Flavor, Basic tastes.
