Document Summary

Chemosense one of the sense modalities that detect the presence of particular molecules in the environment. Papilla small bump on the tongue that contains a group of taste buds. Taste buds a small organ on the tongue that contains a group of gustatory receptors cells. Pheromones chemical signals usually detected by smell or taste that regulate reproductive and social behaviours between animals. Olfactory mucosa the mucus membrane lining the top of the nasal sinuses, contains the cilia of the olfactory receptors. Olfactory bulbs stalk like structures located at the base of the brain that contain neural circuits that perform the first analysis of olfactory information. Receptor cells in the olfactory system have axons that pass through small holes in the bone above the olfactory mucosa and form synapses with neurons in the olfactory bulbs. Olfactory information is sent directly to several regions of the limbic system. Sent to the amygdala and limbic cortex of the frontal lobe.
