Other sensory system CHEMICAL SYSTEM Olfactory system Responsible for smell Inhaling molecules into the nasal cavity and dissolve in the mucus lining It later dissolves in the olfactory epithelium The brain and above the nasal cavity and then those messages are sent straight to the The olfactory cortex in the limbic system is the only Sensation that bypasses the thalamus for faster processing this direct pathway allows for faster more immediate processing of smell which can trigger strong emotional memories and emotional responses pheromones pheromones That's behavior and physical states of others in the same species they play a role in communication like mating and social interaction as well as territorial marking pheromones Without our direct awareness gustation It is our sense of taste There are six different distinguishable flavors that humans can detect Sweet Sour bitter salty Umami Augustus The gustatory system The tongue's taste buds and the neurotransmitters that send the taste or the inform Really of taste of the brain Each taste bud contains receptor cells that respond to different chemical molecules So when food molecules bind with those receptors they convert that information into Electrical signals This is called transduction.. That information is brought up to the thalamus. Sensory interaction The interaction is when two or more senses are triggered at the same time like when you eat food it triggers both taste and smell.
